Is it possible to stop reuse test containers after all integration tests finished-CodePudding

I am using singleton test-container for running multiple integration tests like this :

@SpringBootTest(webEnvironment = RANDOM_PORT)
public abstract class BaseIT {
 
  static final PostgreSQLContainer<?> postgreSQLContainer;
 
  static {
    postgreSQLContainer = 
     new PostgreSQLContainer<>(DockerImageName.parse("postgres:13"))
      .withDatabaseName("test")
      .withUsername("duke")
      .withPassword("s3cret")
      .withReuse(true);
 
    postgreSQLContainer.start();
  }
 
  @DynamicPropertySource
  static void datasourceConfig(DynamicPropertyRegistry registry) {
    registry.add("spring.datasource.url", postgreSQLContainer::getJdbcUrl);
    registry.add("spring.datasource.password", postgreSQLContainer::getPassword);
    registry.add("spring.datasource.username", postgreSQLContainer::getUsername);
  }
}

And then extending from the test the base it

    @SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
class SecondApplicationIT extends BaseIT{
 
  @Autowired
  private TestRestTemplate testRestTemplate;
 
  @Autowired
  private TodoRepository todoRepository;
 
  @AfterEach
  public void cleanup() {
    this.todoRepository.deleteAll();
  }
 
  @Test
  void contextLoads() {
    this.todoRepository.saveAll(List.of(new Todo("Write blog post", LocalDateTime.now().plusDays(2)),
      new Todo("Clean appartment", LocalDateTime.now().plusDays(4))));
 
    ResponseEntity<ArrayNode> result = this.testRestTemplate.getForEntity("/todos", ArrayNode.class);
    assertEquals(200, result.getStatusCodeValue());
    assertTrue(result.getBody().isArray());
    assertEquals(2, result.getBody().size());
  }
 
}

but now the container is runing even after the SecondApplicationIT is finished, how can i stop the container after finishing all test classes which is extending the BaseIt

P.S: i tried with @AfterEach and stopping the container there but it did not work

CodePudding user response：

You can use JUnit extension Testcontainers provides.

Mark the class with @Testcontainers, and the container fields with @Container.

Containers in instance fields will be initialized and stopped for every test case. Static fields will be started once for a class and stopped after.

So something like:

@SpringBootTest(webEnvironment = RANDOM_PORT)
@Testcontainers
public abstract class BaseIT {
 
  @Container
  static final PostgreSQLContainer<?> postgreSQLContainer = 
     new PostgreSQLContainer<>(DockerImageName.parse("postgres:13"))
      .withDatabaseName("test")
      .withUsername("duke")
      .withPassword("s3cret");
 
 
  @DynamicPropertySource
  static void datasourceConfig(DynamicPropertyRegistry registry) {
    registry.add("spring.datasource.url", postgreSQLContainer::getJdbcUrl);
    registry.add("spring.datasource.password", postgreSQLContainer::getPassword);
    registry.add("spring.datasource.username", postgreSQLContainer::getUsername);
  }
}

Note that you're also specifying withReuse(true), which can make the container to not be registered for automatic lifecycle management (if the environment you're running tests opts in for that with testcontainers.reuse.enabled = true in ~/.testcontainers.properties)

CodePudding user response：

Solved it by my own, the .withReuse(true); is not needed there in order to allow the ryuk container to start. the ryuk container will then remove all running containers which is ran by the IT.
