- @Before @After annotations
- Run before and after every test method in the class
- @BeforeClass @AfterClass annotations
- Static methods which are executed once before and after a test class
@Before works with Junit4.class, not with @SpringBootTest
@BeforeEach works with @SpringBootTest
| Junit4 | SpringBootTest | |
|---|---|---|
| before each test | @Before | @BeforeEach |
| after each test | @After | @AfterEach |
| before the class | @BeforeClass |
Example (Junit)
@Slf4j
@RunWith(JUnit4.class)
public class TestJunit {
private List<String> list;
@Before
public void init() {
log.info("[Shark] startup");
list = new ArrayList<>(Arrays.asList("test1", "test2"));
}
@After
public void teardown() {
log.info("[Shark] teardown");
list.clear();
}
@Test
public void middle() {
log.info("[Shark] middle");
}
}
It works
Example (SpringBoot)
@Slf4j
@SpringBootTest
public class TestSpringBoot {
private List<String> list;
@Before
public void init() {
log.info("[Shark] startup-springboot");
list = new ArrayList<>(Arrays.asList("test1", "test2"));
}
@After
public void teardown() {
log.info("[Shark] teardown-springboot");
list.clear();
}
@Test
public void middle() {
log.info("[Shark] middle-springboot");
}
}
It doesn’t work
