"JUnit4概述及利用Annotation简化测试用例编写的教程"

Junit tutorial 1；Junit tutorial 1; JUnit4 Overview JUnit4 is the biggest improvement of the JUnit framework, with its main goal being to simplify the writing of test cases using the Annotation feature of Java 5. Let's first explain what an Annotation is, this word is generally translated as metadata. What is metadata? Metadata is data that describes data. In other words, this thing in Java can be used to modify class names, method names, variable names, just like public, static, etc. The modification describes what the data is used for, similar to how public describes that the data is public. For more details, you can refer to Core Java2. Without further ado, let's get to the point. Let's first take a look at how we write a unit test in JUnit 3. For example, consider the following class: public class AddOperation { public int add(int x,int y){ return x+y; } } We want to test the add method, so we write the unit test like this: import junit.framework.TestCase; import static org.junit.Assert.*; ...
