use less code to improve efficiency. If you are familiar with Java, you will find that annotations is used in a large number of frameworks, such as Java SE 5 and like spring. However, since PHP is not a compiled language like Java, and therefore lacks the mechanism to parse annotations itself, fortunately phpunit to provide such functionality, we take the follo

Unit tests are the most fundamental part of the entire test process, and they require programmers to identify problems as early as possible and to give control, which is one. Also, if there is a problem with the integration test, they can help diagnose. This lays a solid foundation for establishing an efficient event response mechanism in the software development

Integration testing is a test of a unit of work that does not have complete control over the unit being tested and uses one or more of its real dependencies, such as time, network, database, thread, or random number generator. In general, integration testing uses real dependencies, while unit tests isola

its behavior been consistent with what I expected?Writing unit tests, if you only test the correct path of the code, let it go through correctly, not really done. Software development is a very complex project. When testing whether a piece of code is consistent with your expectations, you need to make sure that, in any case, the code is consistent with your expectations: for

What is unit testing?unit testing refers to the inspection and validation of the smallest testable unit in the software. For unit testing in the meaning of the unit, in general, according to the actual situation to determine its specific meaning, such as the C language

In the "programmers who don't write unit tests are not good programmers" principle, I'm sticking with the unit test, not saying that all Java Web applications are based on spring, but at least more than half are spring-based. After discovering bean management through spring, there are a variety of deficiencies in testi
