@After ,@before not working in testcase

问题

I have started testing and now i want to use @After, @Before and @Test but my application only runs the @Before method and gives output on console

before

However, if I remove @After and @Before it runs the @Test. My code is here:

public class TestPractise extends AbstractTransactionalDataSourceSpringContextTests{

    @Before
    public void runBare(){
        System.out.println("before");
    }

    @Test
    public void testingMethod(){
        System.out.println("testing");
    }

    @After
    public void setDirty(){
        System.out.println("after");
    }
}

Why aren't @After, @Test and @before working simultaneously?

回答1:

The AbstractTransactionalDataSourceSpringContextTests class forces the use of the old JUnit 3.x syntax, which means that any of the JUnit 4 annotation will not work.

Your method runBare() is executed not because of the @Before annotation, but because it is named runBare(), which is a method provided by ConditionalTestCase and JUnit TestCase class.

So you have 2 solutions:

Use the AlexR answer to use JUnit 4 tests and Spring;
Keep your inheritance of AbstractTransactionalDataSourceSpringContextTests, but use the onSetUp and onTearDown methods instead of the @Before and @After methods.

回答2:

Use @BeforeEach instead of @Before and @AfterEach instead of @After.

回答3:

It should work... But since you are working with spring framework and JUnit 4 was introduced years ago I's suggest you to use annotations instead of inheritance.

So, annotate you class with @RunWith(SpringJUnit4ClassRunner.class). Remove extends AbstractTransactionalDataSourceSpringContextTests.

Don't forget to make the @Before and @After methods static

Now it should work.

Even if you want to extend Spring abstract test classes at least pay attention that some of them are deprecated. For example class AbstractTransactionalDataSourceSpringContextTests is deprecated.
