Android Applicationtestcase Using A Mockcontext

I'm new to Android testing and I'm trying to create an ApplicationTestCase using a MockContext (well actually I'm trying to use a Renaming Mock Context). But I keep getting an Asse

Solution 1:

As a workaround for that book sample, check the android developer guide to ApplicationTestCase: "If simply run your tests as-is, your Application will be injected with a fully-functional Context" (http://developer.android.com/reference/android/test/ApplicationTestCase.html).

A few lines of the Setup method must be commented to get the test working:

protectedvoidsetUp()throws Exception
    {
        super.setUp();
        // final RenamingMockContext mockContext = new RenamingMockContext(// getContext());// setContext(mockContext);

        createApplication();
        mApplication = getApplication();
    }

Solution 2:

I've used AndroidTestCase to mock a simple context.

classExampleTestextendsAndroidTestCasepublicvoidsetUp() {
      Contextc=newDelegatedMockContext(getContext())
    }

    classDelegatedMockContextextendsMockContext {

    private Context mDelegatedContext;
        privatestaticfinalStringPREFIX="test.";

        publicDelegatedMockContext(Context context) {
             mDelegatedContext = context;
        }

        @Overridepublic String getPackageName(){
            return PREFIX;
        }

        @Overridepublic SharedPreferences getSharedPreferences(String name, int mode) {
            return mDelegatedContext.getSharedPreferences(name, mode);
        }
    }
} 

Its just a bog standard Context, but will get you going
