Problems solved by technology

[0002] Software testing is to describe a process used to promote the correctness, integrity, security and quality of software identification. It is to operate the program under specified conditions to find program errors, measure software quality, and whether it can The process of evaluating to meet the design requirements, software testing is the process of using manual or automatic means to run or test a system, the purpose is to verify whether it meets the specified requirements or to clarify the difference between the expected results and the actual results, it It is a software process that helps to identify the correctness, completeness and quality of computer software (whole or part) that has been developed (intermediate or final version); it is an important aspect of SQA (software quality assurance) Sub-domain, when the intermediate version of the developed software is tested on the test host, due to the imperfection of the software, it may cause the CPU and hard disk of the test host to overclock or run at high speed, and may also cause a sudden increase in power consumption of the test host. The change of voltage will affect the CPU and hard disk of the test host to varying degrees, which may lead to inaccurate tests
