JUNIT4 笔记（四） 测试类——继承关系执行顺序

父类有tearUp和tearDown的代码，如果父类方法被子类覆盖（隐藏了）将不被执行，否则先执行父类的tearUp方法，再执行子类的tearUp方法，先执行子类的tearDown方法，再执行父类的tearDown方法。

不推荐测试类继承另一个测试类。
不推荐测试类有多个@Before，多个@After，多个@ BeforeClass，多个@AfterClass。

ParentTestcase.java

public class ParentTestcase {
	@BeforeClass
	public static void beforeClass(){
		System.out.println("@BeforeClass");
	}
	@AfterClass
	public static void afterClass(){
		System.out.println("@AfterClass");
	}
	@Before
	public void before(){
		System.out.println("@Before");
	}
	@After
	public void after(){
		System.out.println("@After");
	}
	@Test public void test1() {
		System.out.println("@test1");
    	assertTrue(true);
    	}
	@Test public void test2(){
		System.out.println("@test2");
		assertEquals(5,2+3);
	}
}

FirstChildTestcase.java

public class FirstChildTestcase extends ParentTestcase {
	@BeforeClass
	public static void beforeClass(){
		System.out.println("child @BeforeClass");
	}
	@AfterClass
	public static void afterClass(){
		System.out.println("child @AfterClass");
	}
	@Before
	public void before(){
		System.out.println("child @Before");
	}
	@After
	public void after(){
		System.out.println("child @After");
	}
	@Test public void test1() {
		System.out.println("child @test1");
    	assertTrue(true);
    }
	@Test public void test2(){
		System.out.println("child @test2");
		assertEquals(5,2+3);
	}
}

SecondChildTestcase.java

public class SecondChildTestcase extends ParentTestcase {
	@BeforeClass
	public static void childBeforeClass(){
		System.out.println("child @BeforeClass");
	}
	@AfterClass
	public static void childAfterClass(){
		System.out.println("child @AfterClass");
	}
	@Before
	public void childBefore(){
		System.out.println("child @Before");
	}
	@After
	public void childAfter(){
		System.out.println("child @After");
	}
	@Test public void childTest1() {
		System.out.println("child @test1");
    	assertTrue(true);
    	}
	@Test public void childTest2(){
		System.out.println("child @test2");
		assertEquals(5,2+3);
	}
}

执行FirstChildTestcase

1. child @BeforeClass
2. child @Before
3. child @test1
4. child @After
5. child @Before
6. child @test2
7. child @After
8. child @AfterClass

执行SecondChildTestcase

1. @BeforeClass
2. child @BeforeClass
3. @Before
4. child @Before
5. child @test1
6. child @After
7. @After
8. @Before
9. child @Before
10. child @test2
11. child @After
12. @After
13. @Before
14. child @Before
15. @test1
16. child @After
17. @After
18. @Before
19. child @Before
20. @test2
21. child @After
22. @After
23. child @AfterClass
24. @AfterClass
