How To Mock Bundle Method In Android Unit-test?

I have one controller class that handle Fragment creation. Let's say like below: public class FragmentController { public static Fragment newInstance(String title, int total)

Solution 1:

One way could be to use a powerful mocking framework like PowerMock, which can even intercept the construction of new objects.

This should work for you but mocking "simple" classes like Bundle means some effort - you could also use the real implementation by using the UnMock plugin.

Solution 2:

Use the Unmock plugin to un-mock the Bundle class. You'll need to un-mock with Android 4.4 (unmock 'org.robolectric:android-all:4.4_r1-robolectric-1') since later versions of Android reference non-standard Java methods.

You'll also need to keep ArrayMap and MapCollections.
