Instrumentation tests

Instrumentation tests

• Add HiltApplicationTestRunner to execute instrumented android tests with hilt
• Introduce ComposeContentActivity in design module, in order to be able to start single screen instrumented tests in non-app modules - see OnboardingScreenTest.kt in onboarding module for example usage
• Introduce test identifier (test tags) on relevant compose nodes of the screens in order to reference in UI tests
• Introduce some extension helper functions on ComposeTestRule and Modifier
• Add OnboardingScreenTest in onboarding module using fake repository (via a test hilt module) and screen display and click interaction
• Simulator - Introduced the concept of simulators. Wrappers around ComposeTestRule with a DSL-like API to interact with a certain composable screen.
• app
  • AppNavigationTest - Several test methods that invoke navigation via Navigator component and ensure display of the expected screen
  • OnboardingFlowTest tests the display of the initial onboarding screens and the navigation to the next expected one
  • Included several simulators that can also be reused in future tests - We can think of extracting all the simulators in a separate module for reusability among modules

TODO:

• Add Github action to run connectedAndroidTest (issue #21) in CI and include in codecov
