Testing strategy pattern Spring Boot

[uneven dragon]

I have a problem, because I have no idea how to properly test map of @Component.

I mean i have a strategy pattern (implements of interface, which are components) . In Service i have a map of these.

Im using mockito, and i dont know, should i Mock this map or add elements to this in @BeforeEach.

For example:

@Component
@RequiredArgsConstructor
public class Service {

    private final Map<String, Strategy> strategies;

Test:

@ExtendWith(MockitoExtension.class)
public class ServiceTest {

    @Mock
    private Map<String, Strategy> strategies;

    private Service service;

    @BeforeEach
    public void init() {
        service = new Service(strategies);
    }

I just need to know how to test strategy pattern in Spring Boot

[fierce plover]

test each strategy individually, and see if the correct strategy is resolved in your servicetest

[uneven dragon]

Im doing this too

But i need test a Service

Just have no idea how to test Service with map of components

I have tests in Service now, they are working. But i have no idea the idea of mocking map is good

BTW if i use Injectmocks on Service field, tests wont be passing

[fierce plover]

don't mock the map, initialize the map in the constructor, because this should be filled with spring's dependency injection

So just add, dunno, one or two strategies, not even real implementations, the strategies can be mocked

And then test if the resolving of those strategies work

I have no idea what the rest of your code in that service does, so I'm just going off with what you're giving me and how I'd test that

[uneven dragon]

In Service im just creating objects, getting the type of strategy and create object with using strategy

But thanks, that what i needed
