# CI Remediation Summary
|
|
|
|
**Date**: February 5, 2026
|
|
**Task**: Stabilize E2E testing pipeline and fix workflow timeouts.
|
|
|
|
## Problem
|
|
The end-to-end (E2E) testing pipeline was experiencing significant instability, characterized by:
|
|
1. **Workflow Timeouts**: Shard 4 was consistently timing out (>20 minutes), obstructing the CI process.
|
|
2. **Missing Dependencies**: Security jobs for Firefox and WebKit were failing because they lacked the required Chromium dependency.
|
|
3. **Flaky Tests**:
|
|
- `certificates.spec.ts` failed intermittently due to race conditions when ensuring either an empty state or a table was visible.
|
|
- `crowdsec-import.spec.ts` failed due to transient locks on the backend API.
|
|
|
|
## Solution
|
|
|
|
### Workflow Optimization
|
|
- **Shard Rebalancing**: Reduced the number of shards from 4 to 3. This seemingly counter-intuitive move rebalanced the test load, preventing the specific bottlenecks that were causing Shard 4 to hang.
|
|
- **Dependency Fix**: Explicitly added the Chromium installation step to Firefox and WebKit security jobs to ensure all shared test utilities function correctly.
|
|
|
|
### Test Logic Improvements
|
|
- **Robust Empty State Detection**: Replaced fragile boolean checks with Playwright's `.or()` locator pattern.
|
|
- *Old*: `isVisible().catch()` (Bypassed auto-waits, led to race conditions)
|
|
- *New*: `expect(locatorA.or(locatorB)).toBeVisible()` (Leverages built-in retry logic)
|
|
- **Resilient API Retries**: Implemented `.toPass()` for the CrowdSec import test.
|
|
- This allows the test to automatically retry the import request with exponential backoff if the backend is temporarily locked or busy, significantly reducing flakes.
|
|
|
|
## Results
|
|
- **Stability**: The "Empty State OR Table" flake in certificates is resolved.
|
|
- **Reliability**: CrowdSec import tests now handle transient backend states gracefully.
|
|
- **Performance**: CI jobs now complete within the allocated time budget with balanced shards.
