How to test module when it needs Application.class and one is ine the other module?

Question

I have multi-modules gradle project which has follows structure:

Module-A
    main
        java
            com.example.project.main
                Application.class
Module-B
    main
        java
            com.example.project.other
                SomeController.class
    test
        java
            com.example.project.other
                SomeControllerTest.class

I want to test the class SomeController within the test SomeControllerTest. SomeControllerTest demands real application context with some replaced classes. How i can get Application's functional for SomeControllerTest configuring?
