In the unit test in Java: @BeforeClass, @Before, @Test, @After, problems in @AfterClass

Some of the test notes in JUNIT4 are: @BeforeClass, @Before, @Test, @After, @AfterClass

1, which: @BeforeClass, @AfterClass is JUNIT4 in the new add in

2. If run as--->junit Test, running the method containing the @test annotation is, then all annotation methods will be executed, including the Order of execution:

@BeforeClass, @Before, @Test, @After, @AfterClass

3, in JUNIT4, if the test class inherits the TestCase class, then all annotation will not work.

4, Case:

Package cn.edu.hactcm.testjunit;

Import Java.util.UUID;

Import Org.junit.After;

Import Org.junit.AfterClass;

Import Org.junit.Before;

Import Org.junit.BeforeClass;

Import Org.junit.Test;

The result of only executing the Testtest () method is:

public static void Testbeforeclass ()

-------------------------------------

public void Testbefore ()

-------------------------------------

public void Testtest ()
