Testing the reactive output adapters

We need to implement unit tests to ensure the methods from output adapters are working as expected. Here is an example of how we can create unit tests for RouterManagementMySQLAdapter:

@QuarkusTest
public class RouterManagementMySQLAdapterTest {
    @InjectMock
    RouterManagementMySQLAdapter  
    routerManagementMySQLAdapter;
    @Test
    public void testRetrieveRouter() {
        Router router = getRouter();       
        Mockito.when(
        routerManagementMySQLAdapter.
        retrieveRouter(router.getId())).thenReturn(router);
        Router retrievedRouter =     
 ...
