Abstract

The invention discloses a method for automatic testing of RMC software mainly based on the expect tool. The specific steps are as follows: 1. Build a HOST server and install a Linux system; connect the HOST to the RMC network of the cabinet through the network; set up the network so that The HOST server and the RMC of the cabinet are connected and record the RMC IP address; 2. Run the automated test script: first create a configuration file, save the setting values of RMC related items into the file, and then log in from the HOST to the Capture and process RMC-related information on the RMC, save it to a temporary file, and finally use a text editing tool to read the setting values of RMC-related items from the temporary file and compare them with the values in the configuration file to obtain the test results. The use of this method greatly simplifies the testing process of RMC software and reduces the input of manpower.

Description

A method for automated testing of RMC software mainly based on the expect tool

technical field

The invention relates to the technical field of computers, in particular to a method for automatic testing of RMC software.

Background technique

With the continuous development of technology in the IT field, the replacement time of technology is getting shorter and shorter. The product development cycle is getting shorter and shorter. In product development, the importance of testing is getting more and more attention. However, because traditional testing requires a lot of manpower input, it poses great challenges to many companies, especially some small and medium-sized companies. At this time, the automation of testing is particularly important.

RMC is the management module of the cabinet belonging to the Scorpio project, and the Scorpio project is a complete set of cabinet server solutions promoted by the cooperation of Alibaba, Baidu, and Tencent, and participated by many server manufacturers. Intel served as a consultant for the project. The project will be dedicated to advancing the technical development of data center infrastructure and developing open industry specifications. The Scorpio project aims to jointly promote industry cooperation, industry innovation and the application of new technologies, promote the industry to unify the server specifications of the entire cabinet, promote industrial chain support and large-scale production, continuously reduce operating costs, and improve server deployment speed and operation and maintenance efficiency.

RMC mainly consists of two parts, RMC management board and RMC management software. The RMC management software mainly follows the "Rack Management Unit RMC CLI Specification Version 1.0", where the RMC CLI definition refers to the SMASH SM_CLP standard for definition, and the specific reference model is the "Modular System Profile" of SM_CLP (reference: DSP1008). As shown in Figure 2, the tree structure definition of SM_CLP is used to facilitate flexible expansion.

Contents of the invention

The technical problem to be solved by the invention is to reduce manual intervention, save manpower input, and improve testing speed.

The whole test process is mainly based on the operation of the network to the HOST end to the RMC unit, mainly based on the expect tool to realize the automatic execution of the test steps, and the automatic saving and processing of the test results.

Among them, Expect is a free programming tool language used to realize automatic and interactive tasks to communicate without human intervention. Use it to create scripts to provide input to commands or programs, and these commands and programs expect input from the terminal (terminal). Generally speaking, these inputs require manual input. Expect can simulate the standard input according to the prompt of the program to provide the input required by the program to realize interactive program execution.

Expect scripts consist of a series of expect-send pairs: expect waits for a specific character in the output, usually a prompt, and then sends a specific response.

The technical scheme that the present invention takes is: a kind of method mainly based on the automatic testing of the RMC software of expect tool, concrete steps are as follows:

1. Build a test environment:

a. Build the HOST server and install the Linux system;

b. Connect the HOST to the RMC network of the cabinet through the network;

c. Set up the network so that the HOST server and the RMC of the cabinet are connected and record the RMC IP address;

2. Run the automated test script:

First create a configuration file, save the setting values of RMC related items into this file, and then log in to RMC from HOST through expect and capture and process RMC related information and save it to a temporary file. Finally, read the setting values of RMC-related items from the temporary file through the text editing tool and compare them with the values in the configuration file to obtain the test results.

The text editing tool is awk, sed, grep or a small program compiled by oneself.

Here are the tests for various functions:

a. Heat dissipation function test

This process mainly uses expect to log in to the RMC from the HOST to make relevant heat dissipation settings, and record the RMC log and fan speed. Depending on the duty cycle, the fan speed should be inconsistent. In order to judge whether the part of the function is tested or not.

b. Power function test

This process mainly uses expect to log in to the RMC from the HOST to make different settings for the power supply, and judge whether the test is passed according to the power supply status and RMC logs.

c. Node management function test

This process mainly uses expect to log in to the RMC from the HOST to do the following tests on the node: change the IP setting, open the joint node, open the node UID, etc. and save the RMC log and node status. Judge whether the test passes according to the RMC log and node status.

d. RMC management function test

This process mainly uses expect to log in to the RMC from the HOST to set the parameters under the RMC system and judge the test results according to the status after the settings.

e. User testing

This process mainly uses expect to execute different users from the HOST to log in to RMC and execute related commands to test whether the functions of different users are as defined by the product.

f. Other functional tests

This process mainly uses expect and linux scripts to execute related commands from the HOST to test the functions in RMC that are not covered by the above content.

The beneficial effects of the invention are: the use of the method greatly simplifies the testing process of the RMC software and reduces the input of manpower. The application of this method in the product development process truly reflects the automation of testing and the advantages of IT technology. This method also has special reference significance for the testing of other products.
