Robolectric AndroidX fragments NoClassDefFoundError












4















After migration of code and tests to AndroidX, all seems to work pretty well, however Robolectric junit tests for two fragments are failing due to NoClassDefFoundError: androidx/fragment/testing/R$style exception.
The stack trace:




java.lang.NoClassDefFoundError: androidx/fragment/testing/R$style at
androidx.fragment.app.testing.FragmentScenario$EmptyFragmentActivity.onCreate(FragmentScenario.java:79)

at

at
androidx.fragment.app.testing.FragmentScenario.launchInContainer(FragmentScenario.java:265)




For testing fragments I'm using FragmentScenario, and it seems the FragmentScenario.EmptyFragmentActivity refers to a missing R class from a package androidx.fragment.testing.R:




setTheme(getIntent().getIntExtra(THEME_EXTRAS_BUNDLE_KEY,
R.style.FragmentScenarioEmptyFragmentActivityTheme));




Any idea what might be wrong? Maybe I'm missing a dependency that's not that obvious to me.



Reproducible in following project:

          According to answer from Google it is required to include androidx_fragment_test (androidx.fragment:fragment-testing:1.1.0-alpha03) artifact in the testing APK (not in instrumentation APK or testing dependency).



          What this means it has to be added as debugImplementation androix_fragment_test in your build.gradle file.



          If you also run tests on release target then you have to add implementation androix_fragment_test.
