Any annotation to mark a class as a testclass?

问题

I am new to Junit4, I am wondering if there is some annotations to mark a class as a test class just like using

@Test to mark a method as a test method.

回答1:

You can use @Category annotation at class level, like:

@Category({PerformanceTests.class, RegressionTests.class})
public class ClassB {

    @Test
    public void test_b_1() {
        assertThat(1 == 1, is(true));
    }

}

I quoted this example from https://www.mkyong.com/unittest/junit-categories-test/

Also if you run Spring tests, Mockito test with JUnit, then you have to use @RunWith annotation at class level.

For example in Spring boot test I use this:

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT)
public class ControllerTest {

In Mockito (without spring test) test I used:

@RunWith(MockitoJUnitRunner.class)
public class ServiceTest {
