Think in Java notes _chapter20_2_annocation and JUnit

/April 05, 2015 12:13:43 A study of junit based on annotation and reflection:

Package Cn.seven.shengsiyuan.annocation.junitan;import Org.junit.test;public class Junitsource {//The question is why the main method is not written here, Method can be executed directly without being called?? -Reflection @testpublic void Hello () {System.out.println ("Hello World");}}

1. First, get the class object corresponding to the classes you want to test.
2. It then obtains the public decorated method array of the object by reflection
3. Iterate over the array to get each method object
4. Two methods for judging whether the method object is annotated
   1. Method object. isannotationpresent (annotation class. Class)
   2. The annotation class annotation class object =method object. getannocation (annotation class. Class).
5. The method is then executed through Method.invoke.
