Is there a way to rollback a Transaction in Quarkus Unit Tests?

I'm trying to learn some new things using Quarkus, and I kinda got stuck on something: I want to create some tests that are self sustained, I mean, I should be able to run each one independently of each other. I'm using Testcontainers(PostgreSQL) to run some component tests, but I would like to each @Test be able to run on a 'clean database', but I don't think that stoping the container and starting it once again for each @Test would be a good idea. I could have a @BeforeEach(container.dropColumn()) or @BeforeEach(container.truncateColumn()) but: 1 - I don't know if this is the better way, 2 - I don't know how to do this.

Given an hypothetical test scenario:

Scenario 1 - Pass

• Register new User
• Find User by its id
• assert(one_user_on_db)

Scenario 2 - Fail

• Try to Register new User with invalid data
• Find all users
• assert(zero_users_on_db)

The second test fail because the data from the first scenario is still on the database. Here, some code to help.

resources

    @Inject      UserService userService;            @POST      @Transactional      public Response saveUser(@Valid UserDto user){          return Response.status(Response.Status.CREATED)                  .entity(userService.saveUser(user, user.getPassword())).build();      }            @GET      public Iterable<User> findAll(){          return userService.findAll();      }  

tests

@Test  void shouldSuccessfullyCreateUser(){      User mockUser = MockUser.onlyMandatoryFields() //MockUser        given()              .body(mockUser)              .contentType(ContentType.JSON)              .when()              .post("/users").prettyPeek()              .then()              .statusCode(Response.Status.CREATED.getStatusCode());    @Test  void shouldHaveAnEmptyDatabase(){      User[] userList = given()              .contentType(ContentType.JSON)              .when()              .get("/users").prettyPeek()              .then()              .extract()              .response()              .as(User[].class);        assertEquals(0, userList.length);  }  

I've already tried @TestTransaction as described in Quarkus Docs but no success.

I was looking for something like @DirtiesContext from Spring.

Anyway, I've got an open repository, if you want to look further into the code. The tests can be found here.
