Örnek

Şöyle yaparız

datasources:
  default:
    url: jdbc:tc:mysql:8:///db
    driverClassName: org.testcontainers.jdbc.ContainerDatabaseDriver

Ayrıca testleri hızlandırmak için şöyle yaparız

testcontainers:
  reuse:
    enable: true

Açıklaması şöyle

Finally, in order to speed the testing process up, we should try to set a level of isolation in our tests that allow us to reuse the same image, which will reduce our test time dramatically:

MySQLContainer Sınıfı

Örnek

Şöyle yaparız

public static MySQLContainer mySQLContainer = new MySQLContainer("mysql:5.7")
  .withUsername("username")
  .withPassword("password")
  .withDatabaseName("test_db");

Örnek

Şöyle yaparız. Burada normalde container sınıfının start() metodunu çağırmaya gerek yok.

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureWebTestClient
@Testcontainers
class OrderControllerTest {

    static final MySQLContainer MY_SQL_CONTAINER;

    @Autowired
    WebTestClient webTestClient;

    @Autowired
    private OrderEntityRepository  orderEntityRepository;

    static {
        MY_SQL_CONTAINER = new MySQLContainer("mysql:latest");
        MY_SQL_CONTAINER.start();
    }

    @DynamicPropertySource
    static void configureTestProperties(DynamicPropertyRegistry registry){
      registry.add("spring.datasource.url",() -> MY_SQL_CONTAINER.getJdbcUrl());
      registry.add("spring.datasource.username",() -> MY_SQL_CONTAINER.getUsername());
      registry.add("spring.datasource.password",() -> MY_SQL_CONTAINER.getPassword());
      registry.add("spring.jpa.hibernate.ddl-auto",() -> "create");
  }
