Почему mysql testcontainers требуют для запуска свойства соединения jdb c?

Question

Клонирование проблем c repo

Все, что я хочу сделать, - это использовать testcontainers для создания докеризованного экземпляра mysql для запуска интеграционных тестов. Это слишком много, чтобы спросить?

Высокий уровень, я хочу попасть в конечную точку GET и подтвердить, что ответ соответствует тому, что я вставил в базу данных.

тест рассматриваемый файл:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = RestApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ActiveProfiles({"test"})
public class DemoControllerIT {

    @ClassRule
    public static MySQLContainer<?> mySQLContainer = new MySQLContainer<>();

    @Autowired
    private TestRestTemplate testRestTemplate;

    @Autowired
    private DemoRepository demoRepository;

    @BeforeClass
    public static void classSetUp() {
        mySQLContainer.start();
    }

    @AfterClass
    public static void classTearDown() {
        mySQLContainer.stop();
    }

    @Before
    public void setUp() {
        demoRepository.save(new User("username", "password"));
    }

    @Test
    public void testGetUser() {
        ResponseEntity<User> responseEntity = testRestTemplate.getForEntity("http://localhost:8080/getUser", User.class);

        assertEquals("username", Objects.requireNonNull(responseEntity.getBody()).getUsername());

        assertEquals("password", responseEntity.getBody().getPassword());
    }
}

Не могли бы вы попробовать добавить следующий код в ваш тестовый класс:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = RestApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ContextConfiguration(initializers = DemoControllerIT.Initializer.class)
public class DemoControllerIT {

    @ClassRule
    public static MySQLContainer<?> mySQLContainer = new MySQLContainer<>("mysql:8")
            .withDatabaseName("db")
            .withUsername("test")
            .withPassword("test");



    static class Initializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
        public void initialize(@NotNull ConfigurableApplicationContext configurableApplicationContext) {
            TestPropertyValues.of(
                    "spring.datasource.url=" + mySQLContainer.getJdbcUrl() + "?verifyServerCertificate=false&useSSL=false&requireSSL=false",
                    "spring.datasource.username=" + mySQLContainer.getUsername(),
                    "spring.datasource.password=" + mySQLContainer.getPassword(),
                    "spring.jpa.hibernate.ddl-auto=update")
                    .applyTo(configurableApplicationContext.getEnvironment());
        }
    }
