unable to refer app module classes in dynamic feature module when running unit test cases

Question

Our project has dynamic feature module with a dependency on the app module. The classes in the dynamic feature module have a dependency on app module.

We also have unit test cases in the dynamic module testing individual classes of the dynamic module. The unit tests run fine when run through android studio. Got an error running unit tests using gradlew.

Below is the error:

./gradlew :dynamic_feature1:testDebugUnitTest Getting the following error:

15:40:13.225 [DEBUG] [TestEventLogger]
15:40:13.225 [DEBUG] [TestEventLogger] com.example.dynamic_feature1.DynamicPresenterTest > testXyz FAILED
15:40:13.225 [DEBUG] [TestEventLogger]     java.lang.NoClassDefFoundError: com/example/dynamicfeature/AppBase

Answer 1

To fix the java.lang.NoClassDefFoundError: com/example/dynamicfeature/AppBase issue, try this command:

./gradlew test

see Android jUnit Test java.lang.NoClassDefFoundError: android/database/sqlite/SQLiteOpenHelper
