[FIXED] annotations not working when migrating to java 11

Issue

Is there anything i can do to get the @Mock and @InjectMocks annotation to work with java 11?

Solution

Not sure why this worked for you in Java7, but you clearly use @InjectMocks in a wrong way.

@InjectMocks
private ByVehicleIdRequest request = new ByVehicleIdRequest(
   locale,
   additionalInfo,
   permissions,
   switches,
   vehicleId, 
   aftermarketDescriptions, 
   enhancedStringMatchingSettings);

If you use Mockito runner (or extension in JUnit5), you should not initialize the field yourself:

@InjectMocks
private ByVehicleIdRequest request;

As described in MockitoJUnitRunner documentation:

Mocks are initialized before each test method.

If you use the mock values in the field initialization of request object, you are passing not-yet-initialized values to the constructor, and hence null values you observe.

Note

The answer refers to question version 3.
