When we write large programs, we need to write thousands of methods or functions that may be powerful, but we only use a small subset of the functions of the function in our program, and by debugging we can determine that a small subset of the functionality is correct. However, we should also make sure that each function is completely correct, because if we extend the program in the future and use the other

Elementary analysis of unit test of database program Source: internet/Author: Xu ningning/Published: 2007-02-14///> This article is the author's experience in the database functional testing, examples of which are written in the Java language, but I think these ideas for most programming environments are generally applicable. Of course, I'm still working on finding better solutions. The real problem is this
