Description

Technical Field

[0001] The invention relates to the technical field of computer performance testing, in particular to an intelligent computer performance testing system based on Shell scripts. Background Art

[0002] Shell script is a scripting language used for programming and automating tasks in Unix / Linux systems. It can be executed directly in the command line through the interpreter. It can call system commands, manage file systems, perform process control and other operations. Computer use is becoming more and more popular, and corporate office systems are becoming more and more intelligent. If you want to improve the work efficiency of your company, you can make full use of computer systems. With the increase in computer utilization, the performance requirements for computer systems are also increasing, so it is necessary to test the performance of computer systems. However, with the development of computer systems, the types of business are gradually increasing, making system configuration complicated.

[0003] Common computer performance testing systems cannot obtain test information in advance when testing computer systems, and generally use a consistent test sequence and test items for performance testing. The test content cannot be customized according to user needs, resulting in test results that do not meet user needs. In the past, computer performance stress testing often required testers to manually install the compiler environment and configure the mpich2 environment, which required a lot of human-computer interaction. Once operators participated in more testing processes, manual misoperation and other problems may occur, reducing test efficiency and test accuracy, resulting in imperfect computer system performance.

[0004] Therefore, how to improve the automation level of computer performance testing, avoid human-computer interaction, and thus improve testing efficiency and accuracy is a technical problem that needs to be solved urgently. Summary of the invention
