Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The block chain is a multi-party common maintenance, transmission and access safety is guaranteed by using cryptography, and a data consistent storage, difficult tampering and repudiation prevention accounting technology, namely a distributed accounting book technology, can be realized. A blockchain network based on blockchain technology may be understood as a data sharing system for node-to-node data sharing.

Referring to fig. 1a, a schematic structural diagram of a block chain network according to an embodiment of the present invention is provided. In the blockchain network shown in fig. 1a, 100 denotes a blockchain network, and a plurality of nodes 101 may be included in the blockchain network 100, and the plurality of nodes 101 may be terminal devices or servers in the access blockchain network 100. The terminal can be an intelligent collection device, a tablet computer, a notebook computer, a desktop computer, an intelligent sound box, an intelligent watch, an intelligent vehicle-mounted device and the like. The server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, and can also be a cloud server for providing basic cloud computing services such as cloud service, a cloud database, cloud computing, cloud functions, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN, big data and artificial intelligence platform and the like.

In one embodiment, each node 101 in the blockchain network 100 may receive information input into the blockchain network 100 during normal operation and maintain shared data within the blockchain network based on the received input information. In order to ensure information intercommunication in the blockchain network, information connection may exist between each node 101 in the blockchain network, and information transmission may be performed among the nodes through the information connection. For example, when an arbitrary node 101 in the blockchain network receives input information, other nodes 101 in the blockchain network acquire the input information according to the consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes 101 in the blockchain network are consistent.

Each node 101 in the blockchain network has a corresponding node identifier, and each node 101 in the blockchain network can store the node identifiers of other nodes 101 in the blockchain network, so that the node names and the node identifiers are correspondingly stored in the node identifier list according to a node identifier list which can be maintained in other nodes 101. The node identifier may be an IP (Internet Protocol) address or any other information that can be used to identify the node, and table 1 only illustrates the IP address as an example.

TABLE 1

Node name	Node identification
		Node
1	117.114.151.174
		Node 2	117.116.189.145
…	…
		Node N	119.123.789.258

In one embodiment, each node in the blockchain network stores one identical blockchain. The block chain is composed of a plurality of blocks, and fig. 1b is a schematic structural diagram of a block chain according to an embodiment of the present invention. The block chain shown in fig. 1b may include a plurality of blocks, such as block 1, block 2, and block 3, each block includes the hash value of the block and the hash value of the previous block, and the blocks are connected by the hash values to form the block chain. A block chain (Blockchain), which is essentially a decentralized database, is a string of data blocks associated by using cryptography, and each data block contains related information for verifying the validity (anti-counterfeiting) of the information and generating a next block.

In one embodiment, the structure of the blockchain network may be understood as a P2P network. The P2P network is also called a peer-to-peer network, and the node roles in the network can be either a client or a server. Each device in the P2P network can act as both a requester of network services and provide resources, services, and content in response to requests from other devices. The life cycle of the blockchain is as follows: a node in the blockchain network receives a transaction submitted by a user (i.e., the transaction submitted by the user is the information input into the blockchain network described above), and broadcasts the transaction to other nodes through the P2P network; a consensus mechanism randomly selects a billing node, wherein the billing node is called a block-out node or an endorsement node; the accounting node packs and assembles a plurality of transactions into a block to be verified, and broadcasts the block to be verified to other nodes; after receiving the block to be verified, other nodes verify the transaction in the block, vote the block to be verified, and then broadcast the voting information; a certain node performs consensus verification on the block according to voting information from other nodes; after the consensus verification for the block passes, the block is committed to the blockchain storage tier to cause the blockchain storage tier to add the block to the blockchain, and then the generation and consensus of the next block begins.

In the blockchain network, in order to achieve the purpose of multi-center and non-falsification, multiple nodes in the blockchain network need to satisfy a certain fault-tolerant mechanism, such as a byzantine fault-tolerant mechanism, that is, in the blockchain network formed by multiple nodes, if a certain node is down, and the memory is overflowed or is bad, the entire blockchain network can also normally operate.

Only if the blockchain network operates normally, the blockchain service attached to the blockchain network can operate normally. On the contrary, even if the blockchain network can normally operate, the blockchain service deployed in the blockchain network cannot be guaranteed to normally operate. Therefore, after developing a blockchain service, it needs to be tested in the blockchain network, which can be posted after normal operation in the blockchain network. Currently, in the testing process of the blockchain service, code coverage is generally adopted as one of the evaluation means of the test completeness, and the code coverage is the proportion and the degree of the test execution of the program source code described in the software test. Code coverage is the manner derived from systematic software testing, and the basic code coverage criteria are function coverage, instruction coverage, judgment coverage, conditional coverage, and conditional/judgment coverage.

The traditional collection method for the software program code coverage rate usually adopts a coverage rate collection tool matched with a program language, such as Grov in C + +, Jacoco in Java, and GoCov in Go language. The tools can collect the code coverage rate only by safely exiting the tested program, and cannot realize real-time collection, and the service coverage rate of the stand-alone software is usually collected in the prior art, so that the joint coverage rate of a distributed system such as a block chain cannot be counted.

Based on this, an embodiment of the present invention provides a test scheme in a blockchain network, where the blockchain network includes M nodes, each node is deployed with a blockchain code for providing a blockchain service, the blockchain code carries an stub code, and the stub code runs along with the running of the blockchain code in each node, and the running of the stub code can collect code coverage information of the blockchain code in the corresponding node in real time. In the process of testing the block chain service in the block chain network based on the test case set, when a code coverage information collection event exists, acquiring code coverage information corresponding to each node in M nodes at the current moment; further, determining the joint code coverage rate of the block chain network at the current moment according to the code coverage information corresponding to each node in the M nodes, and performing test management on the block chain service based on the joint code coverage rate.

In the test method, the code coverage rate of the block chain network can be collected at any time in the test process, the running condition of the block chain codes can be checked in real time, and compared with the prior art that the code coverage rate can be checked only after the test safety quit, the test convenience is improved. In addition, because the block chain network is a distributed network, all nodes are related to each other rather than independent, and the joint code coverage rate is determined based on the code coverage information of all nodes in the embodiment of the invention, the running condition of the block chain code in the distributed network can be more accurately reflected, and thus the completeness and the accuracy of the test can be improved.

Based on the above test scheme of the blockchain network, the embodiment of the invention provides a test method in the blockchain network. Referring to fig. 2, a schematic flowchart of a testing method in a blockchain network according to an embodiment of the present invention is provided. The testing method in the blockchain network shown in fig. 2 is applied to a blockchain network, where the blockchain network includes M nodes, and a blockchain code for providing blockchain services is deployed in each node of the M nodes, where the blockchain code includes an stub code.

The testing method shown in fig. 2 may be performed by a testing device, and in particular may be performed by a processor of the testing device. The test device may be a terminal or a server. The terminal can be a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart sound box, a smart watch, a smart car and the like; the server can be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, and can also be a cloud server for providing basic cloud computing services such as cloud service, a cloud database, cloud computing, cloud functions, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN, big data and artificial intelligence platform and the like. The testing method in the blockchain network shown in fig. 2 may include the following steps:

step S201, in the process of testing the block chain service based on the test case set, when a code coverage information collection event exists, code coverage information corresponding to each node in M nodes at the current time is obtained.

In one embodiment, the test case set may include a plurality of test cases, which may be written in advance by a tester and used for testing the blockchain service. The execution of the test case suite is triggered by the execution of a test script. Optionally, referring to fig. 3, a schematic diagram of a test case set starting method provided in the embodiment of the present invention is shown. As can be seen from fig. 3, in the test script placement pipeline for starting the test case set, when the blockchain code is submitted to the code management open source platform git, the execution of the pipeline is triggered, that is, the execution of each test case in the test case set is triggered. A plurality of test cases in the test case set are input into the blockchain network one by one, and one test case may be understood as one service or one transaction submitted into the blockchain network.

In one embodiment, the same blockchain code for providing blockchain services is deployed in each of the M nodes of the blockchain network. The blockchain code in each node may be deployed to each node according to the node attribute information of each node after the test device constructs the blockchain network. In specific implementation, node attribute information corresponding to each node in M nodes is obtained; and deploying the block chain code carrying the stub code in each node according to the node attribute information corresponding to each node. The node attribute information of each node may include an Internet Protocol (IP) address, a port number, a user name, and a user password, where the user password may be stored in an encrypted manner. And the test equipment deploys a block chain code into each node according to the node attribute information of each node.

In one embodiment, as test cases are executed in the set of test cases, each node in the blockchain network executes each test case by running the respective deployed blockchain code. With the execution of the blockchain code in each node, the stub code carried in the blockchain code is also run, and each node can count the code coverage information of the blockchain code in the node in real time by running the stub code. In a specific implementation, the stub code of each node may count the code coverage information corresponding to the node once when execution of one test case is completed, perform union operation on the code coverage information counted at the next time and the code coverage information counted at the previous time, and use the operation result as the latest counted code coverage information. When a code coverage information collection event is detected, each node reports the coverage information counted up to the current moment to the test equipment.

In one embodiment, the code coverage information collection event may refer to the receipt of a code instruction, such as a goc server, for triggering the collection of coverage information. In other words, the embodiment of the present invention is implemented by the coverage tool goc based on go language, which is capable of implementing real-time statistics of code coverage information by each node and reporting the counted code coverage information to the test equipment. In the embodiment of the invention, the go coverage tool goc abandons the old go test-c-cover mode in design, and directly interacts with the go tool, so that a series of defects caused by a go test command are avoided. Goc, it does not choose to do the instrumentation by itself, but also considers the compatibility of go language and the performance problem, after all, go tool, originally adopts the structure body to define the counter collector, each file has a separate structure body, the performance contrast is more reliable.

In one embodiment, some of the functional instructions included in the coverage tool goc may be as shown in FIG. 4. For example, the build in fig. 4 is used to compile the code under test as shown in 400 in fig. 4, a binary program with a instrumented version is generated, and in a specific application, a compiling function for the code under test can be started through a code instruction goc build; for another example, the profile is used for displaying the code coverage information of the node to be tested in real time, as shown in 401 in fig. 4, when the function is applied specifically, the function may be started through a code instruction goc profile; as another example, a server is used to implement the initiating coverage information collection as shown at 402 in fig. 4, and in a specific application, the function may be initiated by a code instruction goc server.

In other embodiments, the code coverage information collection event may further refer to detection of completion of execution of any one of the test cases in the test case set. In specific implementation, the test equipment can be preset, when any test case is executed, the code coverage information of each node is collected, and the joint code coverage rate of the block chain network is counted according to the code coverage information of each node.

In one embodiment, the blockchain code may include at least one code module, and the corresponding code coverage information of each node may include a code module in which the blockchain code deployed in each node has been executed, for example, the blockchain code includes code module 1, code module 2, and code module 3; assuming that code module 1 and code module 2 have been executed in the blockchain code deployed in node 1, and code module 2 and code module 3 have been executed in the blockchain code deployed in node 2; then the code coverage information corresponding to node 1 may indicate that code module 1 and code module 2 have been run, and the code coverage information corresponding to node 2 may indicate that code module 2 has been run.

In other embodiments, the code coverage information corresponding to each node may further include a real-time running report of the blockchain code corresponding to each node. The real-time running report of the blockchain code corresponding to each node may include marked blockchain codes, code content in code modules which have been run in the marked blockchain codes may be marked in a first mark form, and code content in code modules which have not been run may be marked in a second mark form. Wherein the first mark form may refer to a first color and the second mark form may refer to a second color different from the first color, for example, the first mark form is green and the second mark form is red; alternatively, the first markup form may refer to a first font, and the second markup form may refer to a second font, for example, the first markup form may refer to a song style, and the second markup form may refer to a regular font.

Step S202, determining the joint code coverage rate of the block chain network at the current moment according to the code coverage information corresponding to each node in the M nodes, and performing test management on the block chain service based on the joint code coverage rate.

In an embodiment, if the code coverage information corresponding to each node includes a code module in which a blockchain code deployed in each node has been executed, the determining, according to the code coverage information corresponding to each node of the M nodes, a joint code coverage rate of the blockchain network at the current time may include: performing union operation on code modules, deployed in each node, of which the blockchain codes are already operated to obtain the code modules, in which the blockchain codes are already operated, in the blockchain network; determining a joint code coverage rate of the blockchain network at a current time based on the total number of the at least one code module and a first number of code modules in the blockchain network for which the blockchain code has been executed.

In the specific implementation, assuming that the blockchain network includes a node 1 and a node 2, and the blockchain codes deployed in the node 1 and the node 2 have already been run as shown in the above example, performing a union operation on the code modules, in which the blockchain codes deployed in the nodes have already been run, refers to: the code module 1 and the code module 2 which have been operated in the node 2 perform union set operation, and the obtained operation result is: code module 1 and code module 2.

The operation result is used as a code module in which the blockchain code is executed in the blockchain network, that is, the code module in which the blockchain code is executed in the blockchain network includes a code module 1 and a code module 2. Further, if the number of code modules of the blockchain code that have been executed in the blockchain network is obtained as 2, and the total number of code modules included in the blockchain code is obtained as 3, then the joint code coverage rate in the blockchain network is equal to the number of code modules that have been executed divided by the total number of code modules included in the blockchain code, that is, the joint code coverage rate in the blockchain network is equal to 2/3.

In other embodiments, if the code coverage information corresponding to each node includes a real-time running report of a blockchain code corresponding to each node, the determining, according to the code coverage information corresponding to each node of the M nodes, a joint code coverage rate of the blockchain network at the current time includes: counting code modules which are deployed in each node and run the blockchain codes according to the blockchain code real-time running report corresponding to each node; performing union operation on code modules, deployed in each node, of which the blockchain codes are already operated to obtain the code modules, in which the blockchain codes are already operated, in the blockchain network; determining a joint code coverage rate of the blockchain network at a current time based on the total number of the at least one code module and a first number of code modules in the blockchain network for which the blockchain code has been executed.

In one embodiment, after the testing device determines the code coverage rate in the blockchain network, the testing device may perform testing management on the blockchain service based on the code coverage rate. In a specific implementation, the performing test management on the blockchain service based on the code coverage includes: if the combined code coverage rate is greater than or equal to a code coverage rate threshold value, determining that the testing of the block chain service is finished, and stopping the testing of the block chain service; and if the joint code coverage rate is smaller than the code coverage rate threshold value, continuously executing the test case set so as to continuously test the block chain service. It should be understood that the higher the code coverage of the blockchain network is, the more code modules are executed in the blockchain network, the more code modules are executed, and the more services provided by the blockchain code are tested, so that the more the test accuracy is ensured.

In the embodiment of the invention, the blockchain network comprises M nodes, each node of the M nodes is provided with a blockchain code for providing blockchain service, the blockchain code carries an stub code, the stub code runs along with the running of the blockchain code in each node, and the running of the stub code can collect the code coverage information of the blockchain code in the corresponding node in real time. In the process of testing the block chain service in the block chain network based on the test case set, when a code coverage information collection event exists, acquiring code coverage information corresponding to each node in M nodes at the current moment; further, determining the joint code coverage rate of the block chain network at the current moment according to the code coverage information corresponding to each node in the M nodes, and performing test management on the block chain service based on the joint code coverage rate.

Based on the above testing method for the blockchain network, an embodiment of the present invention further provides another testing method for the blockchain network, and referring to fig. 5, a flowchart of the testing method for the blockchain network provided by the embodiment of the present invention is shown. The testing method shown in fig. 5 may be performed by a testing device, which may be an end user or a server. The test method shown in fig. 5 may include the following steps:

step S501, node attribute information corresponding to each node in the M nodes is obtained, and a block chain code carrying a pile code is deployed in each node according to the node attribute information corresponding to each node.

Step S502, in the process of testing the blockchain service based on the test case set, when the target test case in the test case set is executed, a code module in which a blockchain code deployed in each node of the M nodes at the current moment is operated is obtained.

As described in the embodiment of FIG. 2, the test cases in the test case set are input into the blockchain network one by one. And with the operation of the block chain codes in each node, the stub codes included by the block chain codes are also operated, and the operation of the stub codes realizes the real-time statistics of the code coverage information of the block chain codes in each node when each test case is completed.

If the test equipment is preset, when the execution of any test case in the test case set is finished, collecting the code module in which the blockchain code deployed in each node in the blockchain network at the current moment is operated, and counting the joint code coverage rate of the blockchain network at the current moment according to the code module in which the blockchain code deployed in each node is operated. The blockchain network detects the execution of each test case in the test case set, and after the execution of the target test case is detected to be completed, the code module in which the blockchain code deployed in each node is operated is obtained. The target test case may refer to any test case in the test case set.

Step S503, performing union operation on the code modules, in which the blockchain codes deployed in each node have been executed, to obtain the code modules, in which the blockchain codes have been executed, in the blockchain network.

And step S505, generating a coverage rate report corresponding to the block chain network according to the joint code coverage rate.

In one embodiment, the coverage report is used to reflect the running proportion and extent of blockchain codes in the blockchain network at the current time. Optionally, the coverage rate report may include marked blockchain code, in the marked blockchain code, the code content in the executed code module may be marked in a first form, and the code content in the code module that is not executed may be marked in a second form.

Wherein the first form may refer to a first color and the second form may refer to a second color different from the first color, such as green for the first form and red for the second form; alternatively, the first form may refer to a first font, and the second form may refer to a second font, for example, the first form may refer to a font, and the second font may refer to a second font. Alternatively, the first form may refer to framing the code content of a code module that has been executed in a first shape box, such as a dashed rectangle box, and the second form may refer to framing the code content of a code module that has not been executed in a second shape box, such as a solid rectangle box. For example, referring to fig. 6, a schematic diagram of a coverage generation report provided by the embodiment of the present invention is shown, where 601 represents the code content in the code module marked in the first form that has been executed, and 602 represents the code content in the code module marked in the second form that has not been executed.

In one embodiment, code coverage may also be included in the coverage generation report, as shown at 603 in fig. 6. The coverage generation report may also include a code coverage evaluation of the current time, such as 604 in fig. 6, where the code coverage evaluation may be "high coverage", "low coverage", and "medium coverage". Optionally, the evaluation of the code coverage condition may be determined by the test device according to the code coverage and a code coverage threshold, assuming that the test device presets two code coverage thresholds, which are a first code coverage and a second code coverage, respectively, and the first code coverage is smaller than the second code coverage; if the code coverage rate of the block chain network at the current moment is smaller than the first code coverage rate, the code coverage condition is evaluated as low coverage rate; if the test equipment determines that the code coverage rate of the block chain network at the current moment is greater than the first code coverage rate and less than the second code coverage rate, determining that the code coverage condition at the current moment is evaluated as the medium coverage rate; and if the code coverage rate of the block chain network at the current moment is larger than the second code coverage rate, the code coverage condition at the current moment is evaluated as high coverage rate.

Step S506, establishing a corresponding relation between the target test case and the code module in the block chain network, wherein the block chain code is operated, and optimizing the target test case based on the corresponding relation.

After the test device determines the code module in which the blockchain code has been executed in the blockchain network through step S503, it may establish a corresponding relationship between the target test case and the code module in which the blockchain code has been executed in the blockchain network.

As an alternative implementation, the test device may optimize the target test case based on a correspondence between the target test case and the code modules in the blockchain network, where the blockchain code has been executed, so that when the blockchain network is tested based on the optimized target test case, the number of the code modules in the blockchain network, where the blockchain code has been executed, is greater than the first number.

In short, when the target test case is definitely executed, after which code modules of the block chain code are executed, the target test case may be modified and adjusted appropriately, so that the modified test case may be executed to cover more code modules in the block chain code.

As another alternative implementation, the test device may store the correspondence in a reference information set used for constructing test cases, where the reference information set may include a correspondence between multiple groups of test cases and code modules in a blockchain network where blockchain codes have been run; further, a new test case is constructed based on the reference information set, so that when the blockchain network is tested based on the new test case, the target code module in the blockchain code in the blockchain network is operated.

In brief, in the testing process of the blockchain service in the blockchain network, the corresponding relations between a plurality of groups of test cases and the operated code modules are collected, and a basis is provided for accurate testing based on the collected corresponding relations.

It should be understood that the above only states that the correspondence relationship between a group of test cases and the code module in the blockchain network, of which the blockchain code has been executed, is obtained, and the correspondence relationship between a plurality of groups of test cases and the code module in the blockchain network, of which the blockchain code has been executed, can be obtained by repeatedly executing the above steps.

For example, the blockchain code may include code module 1, code module 2, and code module 3, and when the blockchain service is tested in the blockchain network through the first test case, code module 1 that collects the blockchain code in the blockchain network is run; at this time, the first test case has a corresponding relationship with the code module 1; when the blockchain service is tested in the blockchain network through the second test case, the code module 2 which collects the blockchain codes in the blockchain network is operated, and at the moment, the second test case and the code module 2 have a corresponding relation.

Subsequently, if the target code module of the block chain code to be tested is the code module 2, the second test case can be directly used as a new test case; if the target code module of the block chain code to be tested is the code module 1, the first test case can be directly used as a new test case; if the target code modules of the block chain code to be tested are the code modules 1 and 2, a new test case can be constructed according to the first test case and the second test case.

In one embodiment, when the test equipment monitors a code instruction to view the code coverage of the node n, the test equipment may display the code coverage of the node n, which is determined based on the number of code modules of the blockchain code deployed in the node n that have been executed and the total number of at least one code module included in the blockchain code, as can be seen in the foregoing. The code instruction for checking the code coverage of the node n may include address information of the node n, for example, the address information of the node n is http://127.0.0.1:36817, and the code instruction for checking the code coverage of the node n may be represented as "goc profile — center =" http://127.0.0.1:36817 "> cov.out & & go tool cover-html = cov.out-o cov.html". When the test equipment displays the code coverage rate of the node n, the test equipment can also display the address information of the node n.

As can be seen from the foregoing, in the embodiment of the present invention, the collection of the overlay information is implemented based on the go language, so that the code instruction for viewing the code coverage of the node n may be input in the editing window of the go language, and the code coverage of the node n may also be displayed in the editing window of the go language. For example, referring to fig. 7, an editing window in a go language is provided, 701 represents code coverage of a node n and address information of the node n collected at two different times.

In the embodiment of the invention, the test equipment acquires the node attribute information of each node and deploys the block chain code for providing the block chain service in each node according to the node attribute information. In the process of testing the block chain service in the block chain network based on the test case set, if a coverage information collection event is detected when the target test case is executed, the code module in which the block chain code deployed in each node is operated is obtained, so that the test is not required to be quitted, the block chain code operation condition in each node can be collected at any time in the test process, and the test convenience is improved.

Furthermore, the test equipment performs fetch-and-gather operation on the code modules, which are deployed in each node and have been run, to obtain the code modules, in which the blockchain codes have been run, in the blockchain network; the joint code coverage of the blockchain network at the current time is then determined based on the total number of code modules included in the blockchain code and the first number of code modules in the blockchain network for which the blockchain code has been executed. It should be understood that after the code coverage information of each node is collected, secondary statistics is performed based on the code coverage information of each node to obtain the joint code coverage rate of the blockchain network, which can reflect the condition that the blockchain code is operated in a distributed network such as the blockchain network, and thus the completeness of the test is improved.

In order to facilitate the generation of subsequent accurate test cases and the optimization of the test cases, the invention can also establish the corresponding relation between the target test case and the code modules of the block chain codes in the block chain network, and then the test cases can be optimized based on the corresponding relation or more accurate test cases can be generated.

(6) In the testing process, a code instruction for collecting code coverage information can be input through the REQ platform, each node reports the dynamically collected code coverage information at the moment, the REQ platform determines the joint code coverage rate of the block chain network according to the code coverage information reported by each node, and generates a coverage rate report according to the joint code coverage rate.
