Errors are the properties of the software and cannot be changed. Testing is the inspection and evaluation of the quality of software products. The basic principles of software Testing: ① Software testing as early as possible, ② avoid checking their own programs, ③ test cases include reasonable input conditions and unreasonable input conditions; ④ test cases should include testing the input data and corresponding expected output, ⑤ pay attention to the cluster phenomenon in the test, ⑥ rigorously execute the test plan, Eliminate the randomness of the test; ⑦ a thorough examination of each test result; ⑧ Save the test process documentation for ease of maintenance. Test documentation includes: test plans, test specifications, test cases, defect reports, and more. Testers must have communication skills, empathy, technical skills, self-confidence, diplomatic skills, a sense of humor, a strong memory, patience, skepticism, self-supervision, insight. Software testing takes several steps, including unit testing, integration testing, validation testing, and system testing. The software test method has static and dynamic test (whether the software needs to be executed), black-and-white box testing (whether for the internal structure of the system and the implementation algorithm). Junit (Supports white-box testing, relatively independent of the code being written), LoadRunner is a common software testing tool.
