Setup

When you create a new Android project using Android Studio, the below dependencies are already added to the build.gradle file.

// Test rules and transitive dependencies:
androidTestImplementation("androidx.compose.ui:ui-test-junit4:$compose_version")

// Needed for createComposeRule(), but not for createAndroidComposeRule<YourActivity>():
debugImplementation("androidx.compose.ui:ui-test-manifest:$compose_version")

1. Create a new test class inside the package androidTest.

2. Example test code MainActivityTest:

• Verifies that both List and Calendar tabs are displayed and selectable.
• Confirms that each tab displays the correct title when selected.
