Containers are not started when using @ImportTestcontainers

[philwebb]

From @sleepo581 in #38831 (comment)

After migrating to spring-boot v3.2.1 tests with @ImportTestcontainers are failing because container is not started.
E.g.:

***************************
APPLICATION FAILED TO START
***************************

Description:

Failed to bind properties under 'spring.datasource.url' to java.lang.String:

    Reason: java.lang.IllegalStateException: Mapped port can only be obtained after the container is started`

public interface Containers {

    @Container
    PostgreSQLContainer<?> postgresContainer = new PostgreSQLContainer<>("postgres:16.1");

    @DynamicPropertySource
    static void setConnectionProperties(DynamicPropertyRegistry registry) {
        registry.add("spring.datasource.url", postgresContainer::getJdbcUrl);
        registry.add("spring.datasource.password", postgresContainer::getPassword);
        registry.add("spring.datasource.username", postgresContainer::getUsername);
    }
 }

@philwebb I've created a simple project with test setup that fails in v3.2.1, but works in 3.2.0.

https://github.com/sleepo581/testcontainers-bug/blob/master/spring-boot-3_2_0/src/test/java/com/example/springboot3_2_0/SpringBoot320ApplicationTests.java

It's project with 2 submodules (3.2.1/3.2.0) with identical code

Note that this only fails when @DynamicPropertySource is used. If @DynamicPropertySource is replaced by @ServiceConnection on the @Container bean field, then the tests will pass.

I confirm the same behaviour, any plans to fix it? Thanks

@goraxan The issue has a regression label and a milestone assigned, which indicates that we plan to address it in a future 3.2.x release.

Hello,
With 3.2.5 DynamicPropertySource is not being called also, which works in 3.2.0 which blocks us from upgrading as of now.

  @Container
  PostgreSQLContainer<?> dbContainer = new PostgreSQLContainer<>(DockerImageName
      .parse("docker.io/postgres")
      .asCompatibleSubstituteFor("postgres")
      .withTag(DEFAULT_POSTGRESQL_TAG));

  @DynamicPropertySource
  static void postgresProperties(DynamicPropertyRegistry registry) {
    registry.add("spring.datasource.url", dbContainer::getJdbcUrl);
    registry.add("spring.datasource.username", dbContainer::getUsername);
    registry.add("spring.datasource.password", dbContainer::getPassword);
    registry.add("spring.datasource.driverClassName", dbContainer::getDriverClassName);
  }

and if I remove DynamicPropertySource and switch to serviceConnections, it does not see it all and spins up the in memory db.
