How to parameterize an InjectMock in a junit ParamterizedTest?

[matter-it-does]

I wish to parameterize a mock instance in a junit @ParameterizedTest but getting an exception.

This way I can test my APIs behaviour in various responses conditions without configuring multiple mocks for every test

TEDIOUS WAY:

@Test
condition1(){
    when(serviceA.do()).thenReturn("1");
    when(serviceb.do()).thenReturn("1");
    // ..
}

@Test
condition2(){
    when(serviceA.do()).thenReturn("2");
    when(serviceb.do()).thenReturn("2");
    // ..
}


@Test
condition3(){
    when(serviceA.do()).thenReturn("2");
    when(serviceb.do()).thenReturn("1");
    // ..
}

@Test
condition4(){
    when(serviceA.do()).thenReturn("1");
    when(serviceb.do()).thenReturn("2");
    // ..
}

DESIRED WAY

stream(){
    mockA1 -> when(serviceA.do()).thenReturn("1");
    mockB1 -> when(serviceb.do()).thenReturn("1");
    mockA2 -> when(serviceA.do()).thenReturn("2");
    mockB2 -> when(serviceb.do()).thenReturn("2");
    
    return stream.of(
        arguments(mockA1, mockB1),
        arguments(mockA2, mockB2),
        arguments(mockA1, mockB2),
        arguments(mockA2, mockB1)
    )
}

@ParameterizedTest
@MethodSource("stream")
test(mockA, mockB){
    // ..
}

MY Attempt code:

@QuarkusTest
public class GreetingResourceTest {

    @Inject
    InsertedService insertedService;

    static Stream<Arguments> mockServices() {
        List<Arguments> args = new ArrayList<>();
        {
            Supplier<InsertedService> foo = () -> {
                InsertedService insertedService = Mockito.mock(InsertedService.class);
                Mockito.when(insertedService.doSomething()).thenReturn("Mocked1");
                return insertedService;
            };
            args.add(Arguments.of(foo, "Mocked1"));
        }
        {
            Supplier<InsertedService> foo = () -> {
                InsertedService insertedService = Mockito.mock(InsertedService.class);
                Mockito.when(insertedService.doSomething()).thenReturn("Mocked2");
                return insertedService;
            };
            args.add(Arguments.of(foo, "Mocked2"));
        }
        return args.stream();
    }

    @ParameterizedTest
    @MethodSource("mockServices")
    public void testHelloEndpoint(Supplier<InsertedService> mock, String expected) {

        QuarkusMock.installMockForInstance(insertedService, mock.get());
        given()
                .when().get("/hello")
                .then()
                .statusCode(200)
                .body(is(expected));
    }

}

/cc @Sgitario (kubernetes), @geoand (kubernetes), @iocanel (kubernetes)

[geoand]

This is a known issue we have with parameterized tests which we hope to address some time in the future

[matter-it-does]

Any good approaches with current state @geoand ?

[geoand]

Nope

[matter-it-does]

I resolved it like

getMock1() -> InsertedService

getMock2() -> InsertedService

test1() -> void {
QuarkusMock.installMockForInstance(getMock1(), insertedService)
//
}

test2() -> void {
QuarkusMock.installMockForInstance(getMock2(), insertedService)
//
}

Had to change @InjectMock to @Inject
