UI Testing with Jetpack and AndroidX

Take your knowledge of UI testing to the next level by writing real UI tests for a demo app that uses:

• Kotlin
• Dagger2
• Navigation Components
• MVI Architecture (repository pattern)
• A real network layer
• Flows and Channel

We'll be using the newest testing tools from androidx including:

• Espresso Idling Resource
• ActivityScenario
• FragmentScenario
• Navigation Testing Artifact

Target Audience:

Those who have some experience writing UI tests. In this course I'll be using the newest tools available so if you think your knowledge of UI testing is getting a bit dated, this will be the perfect course.

WARNING:

There is no database caching in this course. No Room Persistence Library.

What you'll learn:

• Building Test FAKES for any class
• Do not mistake this for mocks. That is something different.
• Custom AndroidJUnitTestRunner
• ActivityScenario
• ActivityScenarioRule
• Types of Mocking and test fakes:

1. Dagger Components
2. Dagger Modules
3. Application class
4. Fragment Factory
5. Glide ImageLoader
6. Retrofit network requests

• Navigation Components:
• Testing navigation (both fragments in isolation and end to end testing)
• Navigation Testing Artifact
• Glide (Setting images in test)
• RecyclerView Testing:
• Scrolling and list item verification
• Clicking items to trigger event
• Stubbing a Test Data Source (Network)
• End-to-end tests with ActivityScenario
• Isolation tests with FragmentScenario
• Configuration changes (activity/fragment recreation)
• Test assets for providing fake network data
• Test Orchestrator:
• Each test runs in its own Instrumentation instance (no/minimal shared state!)
