Episode notes
Unified Gradle Test Runner
- Android Studio now runs instrumented tests through a unified Gradle process for consistency.
- This eliminates discrepancies between test results from Studio and command-line Gradle runs.
Emulator Snapshots for Failures
- The emulator automatically captures snapshots when tests fail, letting you debug failures precisely.
- You can load these snapshots later with breakpoints at failure points for detailed inspection.
Limit Snapshot Storage
- Configure a maximum number of snapshots to avoid consuming excessive disk space.
- Defaults to two snapshots, which is ideal for CI environments to balance resource usage.
