How to use Testcontainers and Dependencie Injection ?

[Samyssmile]

I try to migrate my Integration Test Class to use @testcontainers.

Original Test Class was like

@QuarkusTest
class GameResourceTest {

    @Inject
    TeamService teamService;

    @Test
    void shouldLeadTheRankLadder() {
     teamService.doCrazyStuff();  // PASS

After rewrite it looks like this

@Testcontainers
class GameResourceTest {

    @Container
    private MariaDBContainer mariaDBContainer = new MariaDBContainer("mariadb:10.5.16").withDatabaseName("test").withUsername("test").withPassword("test");
    
    @Inject
    TeamService teamService;

    @Test
    void test() {
     assertTrue(mariaDBContainer.isRunning()); // PASS
    }

    @Test
    void shouldLeadTheRankLadder() {
     teamService <-----------------------IS NULL HERE

So after removing the @QuarkusTest annoation, dependency injection of my service not work anymore.

@QuarkusTest is a Quarkus JUnit extension which takes care of Quarkus startup and provides the test instance which is injected into.
If you remove this extension and replace it with @Testcontainers (which is provided by JUnit and not related to Quarkus in any way), then Quarkus functionality will disappear.

Also, I don't see any tests in Quarkus that would use @Testcontainers ATM so I'd say this isn't supported.
Am I right @geoand?

That is correct.

I have answered the same question on SO BTW

I think that you'll need a custom QuarkusTestLifecycleManager, see https://quarkus.io/guides/getting-started-testing#launching-containers for more info. FYI I've found this video from Alex Soto Bueno about Quarkus and Testcontainers: https://www.youtube.com/watch?v=xtQ1GmVpPP0 . It might be outdated though - made in 2019 ;-).

Ok, I solved it with QuarkusTestLifecycleManager. I missundertood the @testcontainers Annotation. For me it was like 'add @testcontainers and define MariaDB will force the test automaticly use the Testcontainer for all transactions.

With QuarkusTestLifecycleManager it works as expected. This is closed. Thank you
