Most Java development environments have integrated JUnit as a unit test tool. "      " JUnit is a regression testing framework (regression testing framework) written by Erich Gamma and Kent Beck. JUnit testing is a programmer's test, the so-called white-box test, because the programmer knows how the software being tested (how) accomplishes the function and what it does. JUnit is a set of frameworks that inherit the TestCase class and can be automatically tested with JUnit.

Extreme programming requires testing before writing code, so that programmers can write code before the function and logic of the code, otherwise the test code and the code to be tested in the event of an error, both need to maintain, but more delay time. In terms of code refactoring, testing can reduce the time consumed by regression errors. 1.2.3JUnit assertion function           If the code is wrong, JUnit will tell you which test did not pass and why not. 1.3 Feature  junit is an example of Xunit for the unit Test framework system. 1.3.1JUnit is the assertion used to test the desired result. 1.3.2JUnit is a test runner for graphical and textual testing. 1.3.3JUnit is a test suite for easy organization and running tests.  2.javascript Unit Test Tool--google JSTest2.1 definition and introduction      google JS test is a JavaScript unit test framework running under the V8 JavaScript engine, Google JS Test is responsible for testing Chrome's JS execution speed inside Google, which is now open for everyone to use in open source engineering. 2.2 Feature 2.2.1 does not need to be run in the browser. There is an ultra-fast startup speed and execution speed. 2.2.2 Output results are simple and easy to read. The 2.2.3Google JS test has an optional browser-based tester. The 2.2.4 Matching system allows expression testing and can visually read the error message of the output. 2.2.5 has a number of matching device built-in, users can also add their own.
