Summary

  • Split the single CI job into three parallel jobs:
    1. flutter-tools-tests: Runs on ubuntu + macOS (unchanged behavior)
    2. shorebird-android-tests: Runs on Ubuntu only (faster runners)
    3. shorebird-ios-tests: Runs on macOS only (requires Xcode) + Android smoke test

Performance Improvements

Before (sequential on each platform)

  • macOS job: ~21 minutes (flutter tools + all shorebird tests)
  • Ubuntu job: ~12 minutes (flutter tools + all shorebird tests)
  • Total wall-clock: ~21 minutes (limited by slowest)

After (parallel jobs)

  • flutter-tools-tests: ~2-3 min each platform
  • shorebird-android-tests (Ubuntu): ~8 min
  • shorebird-ios-tests (macOS): ~15 min
  • Total wall-clock: ~15 minutes (limited by iOS tests)

Savings

  • ~6 minutes faster wall-clock time (21m → 15m)
  • Android tests run on faster Ubuntu runners instead of macOS
  • Better CI minute efficiency (no duplicate Android testing on macOS, just smoke test)

Other Benefits

  • Parallelism: All jobs run simultaneously
  • Cleaner config: Removed Windows from matrix (nothing was running there anyway)
  • Better failure isolation: Easier to see which platform/test type failed
  • macOS still runs a single Android smoke test to catch platform-specific issues

Test plan

  • CI should now show 4 separate jobs (2 flutter-tools + 1 android + 1 ios)
  • All tests should pass

chore: split CI into parallel jobs

Split the single CI job into three parallel jobs:
1. flutter-tools-tests: Runs on ubuntu + macOS (unchanged)
2. shorebird-android-tests: Runs on Ubuntu only (faster runners)
3. shorebird-ios-tests: Runs on macOS only (requires Xcode)

This improves CI performance by:
- Running all jobs in parallel instead of sequentially
- Moving Android tests off macOS to faster Ubuntu runners
- Removing Windows from the matrix (nothing was running there anyway)

Expected speedup on macOS: ~5 minutes (no longer runs Android tests)
