The flow of the test method is described below with reference to fig. 1:

step 101: the client acquires the test script.

Specifically, the client has a data input interface through which a user can import a manually written test script, and the client obtains the test script. The test script is computer readable instructions in the testing process.

Step 102: the client transmits an excitation signal to the operation simulation device according to the test script.

Specifically, the client executes each instruction in the test script, generates an excitation signal corresponding to the instruction, and sends the excitation signal to the operation simulation device. The client is provided with a test platform access interface which is used for executing signal setting instructions of test cases and realizing data excitation based on interface call of a test verification environment.

Step 103: and running the simulation device to simulate the cabin display system to execute the test operation corresponding to the excitation signal and display a test display interface comprising the test operation result.

Specifically, the operation simulation device is used for simulating the cockpit display system, the cockpit display system comprises a CDS end and a UA end, and the operation simulation device comprises a display component which is used for displaying pictures in the simulated UA end. The operation simulation device receives the excitation signal, the CDS end in the operation simulation device is triggered by the excitation signal to execute the test operation corresponding to the excitation signal, and the operation simulation device displays the display state of each UA in the cabin display system, namely, the display interface in the operation simulation device displays the test display interface of the test operation result. The client may send an indication to the server after sending the excitation signal, where the indication is used to instruct the server to collect a test display interface of the running simulation device. The client may also instruct the server to monitor the test display interface of the running simulation device within a preset period of time.

Step 104: and the server acquires a test display interface for running the simulation device according to the instruction of the client.

Specifically, the server is deployed in a high-performance computer with a graphics card and an image acquisition card. The client is also provided with a server communication interface, and the server communication interface realizes data interaction with the server based on http, and comprises the following steps: and detecting the state of the server, testing the identification result and the like. The line between the server and the client for transmitting data may be an ethernet line. The server receives the indication and collects a test display interface of the running simulation device, which in this example may be collected by a camera.

Step 105: and the server identifies the test display interface to obtain a test identification result.

And identifying the identifiable objects in the test display interface according to the image identification network trained to be converged in advance. The recognizable objects in the test display interface may be text, images of controls, etc.

The neural network combined mode is adopted to construct a related recognition model library aiming at the characteristics of different controls in the cabin display system, and a better recognition effect is achieved by preprocessing images through a computer vision technology. The training that uses in the training process is that the server stores the image of sample display interface that 3 sets at least different image acquisition equipment gathered, and wherein, the neural network model that the system used has in the aspect of the deep learning: the convolutional neural network CNN, CNN network is to utilize convolutional operation based on convolutional kernel and multi-layer (convolutional layer, pooling layer, full-connection layer) structure to realize the high-efficiency classification of the image; the network FASTER RCNN and the network RCNN can be adopted to position the specified characteristic images in the test display interface based on the network obtained by training, such as pointers, characters and the like; and calling other algorithms or network models after the positioning is finished to realize further content identification. The LSTM network can be adopted, is a special cyclic neural network, can control the transmission state through the gating state, is more beneficial to memorizing information which needs to be memorized for a long time and forgetting some unimportant information, and is used for identifying a text related model.

Step 106: and the server transmits the test identification result to the client.

Step 107: and the client determines the test result according to the received test recognition result and a prestored recognition result of the expected display interface.

Specifically, the client may store the identification result of the tested expected display interface in advance, compare the test identification result with the identification result of the expected display interface, if the state of each control in the identification result is the same as the state of each pre-stored control, determine that the test is qualified, and if the states are different, determine that the test is unqualified. After obtaining the test results, a test report may be generated that the client supports exporting into pdf or txt formats.

It should be noted that, the test script includes a plurality of test cases to be tested, the client supports adding the test script into the execution list, and executes all the test cases in the script, and the execution process includes data excitation, waiting, result determination, etc.

The embodiment of the application realizes the testing method which comprises the steps of obtaining the testing script, executing the testing script and recording the testing result; realizing the full-automatic execution of the test case; in the process of testing the script, the server controls the industrial camera to complete image acquisition and execute information (such as text content, color, control state and the like) extraction of the appointed identification target and identification result return.

In one embodiment, the acquisition test script in the test method is generated by a client, and a schematic diagram thereof is shown in fig. 2.

Step 1011: and receiving configuration information of each test item determined by a user, and generating a test script.

Specifically, the configuration information may be input by a user, for example, a test case editor may be displayed on a display interface on the client, and the client edits a test case according to a selection instruction, where the selection instruction is used to instruct a test control or instruction in the test case editor selected by the user, and the selection instruction may be a click. For example, the display interface receives an instruction from a user to select a SET control or other command control related to parameters in an interface definition file (INTERFACE CONTROL DOCUMENT, ICD), and the client dynamically provides selectable parameter prompts according to the currently selected control of the user in combination with ICD parameter configuration when the parameters are input; the user can input parameters based on the optional parameter prompt; a test script is automatically generated.

The test method further includes the client querying parameters in the interface definition file.

Specifically, the client receives a query request from a user, queries parameters in the interface definition file according to the query request, and queries ICD parameters so as to quickly generate the test script. For example, the query result is displayed, an input selection instruction is received, single or multiple parameters in the query result are obtained, and the client terminal completes automatic generation of the test script corresponding to the test item based on the selected parameters. The test script comprises the execution sequence of each test case.

It should be noted that, the testing method adopts an asynchronous execution mechanism, and adopts an asynchronous testing mechanism, so as to reduce occupation of the main thread and avoid the problems that the occupation time of the main thread is too long and the testing speed is affected. An asynchronous test execution mechanism is adopted, namely, process control is performed when a test is executed, and the problem of overlong response time caused by occupation of a main thread is avoided.

In the embodiment, the test script does not need to be written manually, so that the test efficiency is improved.

In one embodiment, the client verifies the test script, a schematic diagram of which is shown in FIG. 3.

Step 102-1: and detecting the validity of the test script according to a pre-stored interface definition file.

In the traditional mode, all test cases of a user are written based on Excel, and ICD parameter configuration of an SSDL platform cannot be timely and effectively obtained in the writing process, so that errors which cannot be identified by signals in actual operation of a finally completed test script, namely CVT invalid errors, are easy to occur. Meanwhile, due to the fact that the update frequency of the SSDL platform is high in a production environment, a tester often needs to consume a great deal of time and effort in verifying the correctness of the test script.

Before executing the test script, the validity of the test script is checked, and the checked content comprises the validity of the parameters and the validity of the parameter values, so that the accuracy of the test script can be ensured.

The process of validity verification of the parameters may be: and acquiring an interface definition file of the test item, and acquiring parameters in the interface definition file. And acquiring the test script, and detecting whether the test script comprises all parameters in the interface definition file of the test item, if not, indicating that the current test script has missing parameters.

The method can also be realized by detecting whether the pre-stored parameter value is the same as the corresponding parameter value in the test script.

Step 102-2: and if the invalid information exists in the test script, indicating the position of the invalid information.

And after the verification is finished, outputting all error reasons and position information for a user to check.

In this embodiment, since the test script includes a plurality of test cases, if the test script is manually detected, the workload is large, and the manual detection is not required in this embodiment, so that the detection efficiency is improved, and meanwhile, the accuracy of the test is improved.

In one embodiment, the client stores each version of the test script in a database for viewing by a tester, a schematic diagram of which is shown in FIG. 4.

Step 102-3: the client saves the test script of each version into a database, and the test script corresponds to the respective identification information.

Specifically, the client is further provided with a database access interface, the database access interface is used for storing and reading data in a database, and the database can be a MySQL database. Because of the update of the test scripts, each version of the test scripts can be stored in the database, and meanwhile, the identification information of each version of the test scripts is stored in the database. The procedure for saving the test script is as follows:

When the test script is executed, the client generates a unique turn number according to the content and version of the test script; and storing all relevant test processes and result data including the acquired images under the turn in the test execution process for the test personnel to check.

The test system in this example may also monitor parameters selected by the user, who may select parameters from the input/output of the client; the numerical value of each parameter is monitored, the monitoring duration can be set according to the needs, and the monitored parameters can be refreshed manually or refreshed at regular time by the system so as to adapt to different testing scenes.

The client supports the importing of Excel format user test scripts, and can perform operations such as searching, updating, checking and deleting on the test scripts of the importing system.

In this embodiment, each version of the test script is saved and the test script is queried later for study by the tester.

In one embodiment, the client provides at least two test modes, a schematic of which is shown in FIG. 5.

Step 104-1: the client displays at least two preset test mode options so that a user can select a test mode through a display interface.

Step 104-2: and the client responds to the selected test mode and tests the simulated cabin display system according to the test mode.

The test mode includes two modes, an adaptive mode and a full-automatic mode. The self-adaptive mode refers to a mixed test which is supervised by people, and can be automatically switched between a semi-automatic execution mode and a full-automatic execution mode according to the type of the test step; the full-automatic test step will be skipped automatically; the full-automatic mode refers to an unsupervised long-time full-automatic test, and the semi-automatic test steps will be skipped automatically, and for possible errors in operation, such as: the use case contains illegal signals or SSDL call errors, etc., the user confirmation dialog box is popped up, and error information is recorded.

In this embodiment, multiple test modes are provided for the user to select, so as to improve the flexibility of the test.

In one embodiment, the client may also process the on-board data, a schematic diagram of which is shown in fig. 6.

Step 102: and the client sends an excitation signal to the operation simulation device according to the test script.

Step 104-2: and the client responds to the selected test mode, and tests the simulated cabin display system according to the test mode.

Step 108: and the client acquires the airborne data of the airborne equipment.

The on-board data indication refers to data collected by on-board equipment, such as an aircraft. The on-board data may be imported to the client by other devices.

Step 109: the client analyzes the airborne data and obtains all parameters in the airborne data.

Step 110: and the client draws a curve corresponding to the airborne data according to each parameter in the airborne data and a prestored airborne interface definition file.

Specifically, the airborne data is analyzed, and each parameter in the airborne data is acquired so as to simulate the airborne data or analyze and process the airborne data. And a pre-stored airborne interface definition file can be allocated for the airborne data, and a curve corresponding to the airborne data is drawn according to allocation time sequencing.

It should be noted that, the test system in this embodiment performs deployment test in a laboratory environment, and can continuously run automatic test for more than 10 hours in an unsupervised laboratory environment, so as to ensure continuous working time; the average operation response time is less than 1 second, and the heavy load operation response time is less than 2 seconds; when the length of the airborne data file to be analyzed is tested, the prototype system can analyze the airborne data file with the size of more than 2GB, and meanwhile, the number of parameters of a single airborne data file can realize the analysis of the airborne data file with the size of more than 200 parameters; recording the data processing time of a single record file during testing, wherein the time for actually measuring and analyzing the airborne data file with the size of 2GB is about 6 minutes; in the image processing module of the server, the pictures with different test display interfaces are used for testing, so that numerical information, english sentences and linetypes in the pictures can be successfully identified. Wherein the numerical information includes: the content, color, position and duration of the numerical values, the english sentence includes: the appearance (Appear) and Disappearance (DISAPPEAR) of English sentences, the color, position and duration of the sentences; the line type includes: the state of the line (combination of color, length and thickness) and duration.
