Walkthrough

This pull request adds comprehensive test coverage across the Balloon UI library, encompassing build configuration updates, test infrastructure setup, and extensive unit and instrumentation tests for core components including BalloonState, BalloonStroke, TextForm, IconForm, enums, and Compose integration. Approximately 15 new test files and 3 build configuration files were introduced.

Changes

Cohort / File(s)	Summary
Build & Gradle Configuration balloon/build.gradle.kts, balloon-compose/build.gradle.kts, gradle/libs.versions.toml	Added testInstrumentationRunner, Kotlin test compilation opt-in flag for InternalBalloonApi, and expanded test dependencies (JUnit, Truth, Robolectric, MockK, Compose test artifacts, AndroidX Test libraries).
Test Infrastructure & Manifests balloon/src/androidTest/AndroidManifest.xml, balloon/src/androidTest/kotlin/com/skydoves/balloon/TestActivity.kt	Introduced AndroidManifest for instrumentation tests declaring TestActivity as main entry point, and created TestActivity scaffolding extending android.app.Activity.
Balloon Instrumentation Tests balloon/src/androidTest/kotlin/com/skydoves/balloon/BalloonTest.kt	Added comprehensive instrumentation test suite exercising Balloon.Builder configurations including text, arrow, size, background, animation, dismissal, overlay, and event listener properties via ActivityScenario.
Balloon Unit Tests balloon/src/test/kotlin/com/skydoves/balloon/BalloonEnumsTest.kt, BalloonSizeSpecTest.kt, BalloonStrokeTest.kt, IconFormTest.kt, TextFormTest.kt	Added unit tests validating enum values, BalloonSizeSpec wrap behavior, BalloonStroke data class properties, IconForm builder defaults and configuration, and TextForm builder DSL with Robolectric and Truth assertions.
Compose Module Tests balloon-compose/src/androidTest/kotlin/com/skydoves/balloon/compose/BalloonComposeTest.kt, balloon-compose/src/test/kotlin/com/skydoves/balloon/compose/BalloonComposeExtensionTest.kt, BalloonLayoutInfoTest.kt, BalloonStateTest.kt	Added Compose-specific test suites covering BalloonState lifecycle, attachment, builder configurations, visibility control, arrow orientations, overlay behavior, independent state instances, and BalloonLayoutInfo data class semantics.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20–25 minutes

• BalloonComposeTest.kt: Most complex test file with comprehensive UI state and interaction coverage; requires careful review of test logic and assertions.
• Build configuration changes: Verify dependency versions and test runner setup are correct across both modules.
• Pattern consistency: Multiple files follow similar testing patterns (builder validation, data class testing); spot-check a few to confirm consistency, then skim remaining.
• Test infrastructure: Ensure TestActivity and manifest setup properly support instrumentation tests.

Poem

🐰 With test files gathered, so many and bright,
Builders and states now shining in light,
From Compose to core, coverage takes flight,
Each assertion verified, everything right! ✨
