# Sprint 1: E2E Test Improvements

*Last Updated: February 2, 2026*

## What We Fixed

During Sprint 1, we resolved critical issues affecting E2E test reliability and performance.

### Problem: Tests Were Timing Out

**What was happening**: Some tests would hang indefinitely or timeout after 30 seconds, especially in CI/CD pipelines.

**Root cause**:

- Config reload overlay was blocking test interactions
- Feature flag propagation was too slow during high load
- API polling happened unnecessarily for every test

**What we did**:

1. Added smart detection to wait for config reloads to complete
2. Increased timeouts to accommodate slower environments
3. Implemented request caching to reduce redundant API calls

**Result**: Test pass rate increased from 96% to 100% ✅

### Performance Improvements

- **Before**: System settings tests took 23 minutes
- **After**: Same tests now complete in 16 minutes
- **Improvement**: 31% faster execution

### What You'll Notice

- Tests are more reliable and less likely to fail randomly
- CI/CD pipelines complete faster
- Fewer "Test timeout" errors in GitHub Actions logs

### For Developers

If you're writing new E2E tests, the helpers in `tests/utils/wait-helpers.ts` and `tests/utils/ui-helpers.ts` now automatically handle:

- Config reload overlays
- Feature flag propagation
- Switch component interactions

Follow the examples in `tests/settings/system-settings.spec.ts` for best practices.
