The purpose of software test determines how to organize tests. If the purpose of the test is to find the error as much as possible, the test should be directly part of the software complicated or more than the previous error. If the test is to provide end users with quality assessment with certain credibility, the test should be directly for commercial hypotheses that are often used in practical applications. Different institutions will have different test purposes; the same institutions may have different test purposes, which may be testing different levels of different areas or different levels of the same area. When talking about software testing, many people collect GRENFORD J. Myers in the "The Art of Software Testing" book: 1, software testing is to find errors and execute the process of executing the program; 2, test is to prove the program It is wrong, not the procedure has no error. 3, a good test case is that it can discover the mistakes that have not been discovered so far; 4, a successful test is to discover the undisputed testing of the wrong test. This point of view can remind people to test to find errors, rather than demonstrating the correct functionality of software. But only literally understanding, this point may generate misleading. It is considered that the error is the only purpose of software testing. It is not worth testing that there is no error. This is not the case. First, the test is not just to find out the error. By analyzing the causes of errors and errors, the project manager can help the project manager discover the shortcomings of the software process currently used to improve. At the same time, this analysis can also help us design a targeted detection method to improve the effectiveness of the test. Second, no error detection is also valuable, complete testing is a method of assessing test quality. The detailed and rigorous reliability growth model can prove this. For example, Bev Littlewood discovered a test that was tested and n-hour, the system continued to operate n-hours.
