Recommendation 155: Submit unit test code along with production codeLet's start with a question: Are we afraid to change the code? Have you ever faced a messy code, determined to refactor, and then received a report from the beta in Monday, one months later: The new version, with no previous version stability, worse performance, and bugs seem to have changed a lot. In other words, the refactoring code looks
IntroductionThe use of unit testing when running a program is an important indicator of the quality of a programmer. The use of unit testing allows me to check the correctness of the program logic and also let us reduce the program testing bugs, easy to debug can improve our writing program efficiency. We used to use junit when we were doing unit tests, just to i
01 Overview
JUnit is a regression testing framework (regression testing framework) written by Erich Gamma and Kent Beck. The JUnit test is a white-box test. JUnit has its own JUnit expansion biosphere. Most Java development environments have integrated JUnit as a unit test tool. [1] JUnit is an open-source

This can involve, for example, creating a temporary or proxy database, a directory, or starting a server process. The test case test case is the smallest unit

handling exceptions. In unit testing, we should test the error processing logic by simulating exceptions.
However, it must be noted that, if the method itself is not required to handle certain exceptions, it is not necessary to perform a robustness test on the method. only perform robustness tests on the code that really requires exception handling.

new functions are added, the old functions must be re-tested, this results in a lot of time required for regression testing. A lot of repetitive work is generated here, and some of these repetitive work can be completed automatically, at this time, UITests can help solve this problem.Simplest unit test
