There is no doubt that programmers are good at thinking about problems. A program is written through the basic stages of thinking, design, writing, debugging, testing, and running. But most programmers have a problem that they are reluctant to test their own code. After the debugging is completed, they think that the work is over. testing is the work of testers. Theoretically, if there is a problem with the code, the tester and the end user will certainly be able to find these
