Is there any sample for multiple modules app with espresso and dagger android

Scenario
- app module contains the app component with its modules for inject sub modules dependencies
- module1 contains activity with its own espresso test
- module2 contains activity with its own espresso test
- module1 start activity from module2
- module2 throw
```
java.lang.IllegalArgumentException: No injector factory bound for Class
```

The issue describes an app module plus module1 and module2, with LoginActivity failing because no injector factory is bound. Start by clarifying whether the requested outcome is a sample or a fix, then inspect the multi-module Espresso and Dagger setup. Done would require a documented or working example that resolves the reported failure.
