A first look at PHP unit testing tools: PHPUnit_PHP tutorial

Have you encountered the following situation in the process of program development: After you spent a long time developing a PHP application, you thought it was done. Unfortunately, during debugging, you kept discovering bugs. And the scariest thing is that these bugs appear repeatedly. You may find that these bugs are related, but you can't always find the problem.

When you encounter the above frustrating situations, you will definitely wonder what better way to solve it? Of course there is a way! This is to use unit testing. Unit testing can not only solve the above headaches to a certain extent, but also make the code easier to maintain, and can also allow you to refactor the code more.

Once you write the unit test cases, when you need to modify your code, what you have to do is to re-run your unit test cases and observe whether these unit test cases pass. If they pass, prove that the code is no problem.

People often say: Since unit tests are so good, why are so many people still reluctant to write unit tests? There are the following misunderstandings:

1. Thinking that writing unit tests is a waste of time. Although many IDE tools currently have established frameworks for writing unit tests, developers still need to write some unit test code. Like many best practices in development, using the right method to do the right thing will save a lot of time in development. Whenever a new feature is added, you may click on manual testing by visiting your web page everywhere, and running the created unit test cases is actually faster than testing manually.

2. I think that since the code can run, there is no need to write unit tests. But suppose there are new members in the team. If there are no good unit test cases, the new members are likely to code casually without considering the consequences. If you have well-written unit tests and perform various tests while the program is running, you can avoid bugs to the greatest extent.

3. I think writing unit test code is boring. The nature of programmers is to solve problems, and many programmers think that writing unit test code during intense coding work will be boring. But what you need to know is that if you can find as many errors in the code as possible at a very early stage by writing unit tests, then it will save time and reduce errors, why not?
