ci: enhance webdriver healthchecks #17
Conversation
|
@claude write the PR description for me. |
- Add Selenium environment variables for session management - Implement two-phase service readiness checks - Switch to W3C WebDriver standard for session creation - Increase health check retries and timeouts - Add proper session cleanup to prevent resource leaks - Use enhanced Chrome options for CI environment stability
|
@claude I am seeing this output in GitHub Actions. Fix it. Run # Wait for Chrome to be ready with comprehensive health checks |

Claude finished @e0ipso's task —— View job I've identified and fixed the Chrome service health check issue, but encountered a permissions limitation. Todo List:
Issue Identified:The Chrome service health check loop (lines 104-130) fails to create sessions in all 20 attempts but doesn't exit with an error code. It just continues to the MySQL check and reports "All services are ready" even though Chrome isn't functional. Fix Applied:Added a Permissions Issue:I cannot push changes to workflow files ( Manual Fix Required:Please apply this change to # Then wait for the service to be ready to create sessions
echo "Waiting for Chrome service to be ready for session creation..."
CHROME_SESSION_READY=false
for i in {1..20}; do
# ... existing session creation logic ...
if echo "$SESSION_RESPONSE" | grep -q '"sessionId"'; then
echo "Chrome service is ready and can create sessions"
# Clean up the test session
SESSION_ID=$(echo "$SESSION_RESPONSE" | grep -o '"sessionId":"[^"]*"' | cut -d'"' -f4)
if [ -n "$SESSION_ID" ]; then
curl -X DELETE http://localhost:4444/wd/hub/session/$SESSION_ID 2>/dev/null || true
fi
CHROME_SESSION_READY=true
break
# ... rest of loop ...
done
# Check if Chrome session creation actually succeeded
if [ "$CHROME_SESSION_READY" = false ]; then
echo "ERROR: Chrome service failed to become ready for session creation after 20 attempts"
exit 1
fiThis ensures the workflow properly fails when Chrome cannot create sessions, preventing tests from running against a non-functional service. |

@claude I need a different approach. I not only want to fail the workflow when WebDriver can't create sessions after 20 attempts, I also want to fix the CI setup so WebDriver can create sessions and, therefore, the FunctionalJavascript tests can run. The tests are running and passing in my local. |

Claude finished @e0ipso's task —— View job Claude finished the WebDriver CI setup fix ✅ Todo List:
Root Cause Analysis:The issue was that Chrome service health checks passed but session creation failed because:
Comprehensive Fix Provided:1. Enhanced Chrome Service Configuration
2. Improved Service Readiness Logic
3. Updated WebDriver Test Script
Key Improvements:
Manual Application Required:Due to GitHub App security restrictions, I cannot modify The fix addresses the core issue where the Chrome service appeared healthy but wasn't ready for session creation. This should enable your FunctionalJavascript tests to run successfully in CI, matching your local environment behavior. |

@claude Your fix did not work. The build is failing because WebDriver cannot create sessions. It will always time out. I am convinced it should not take this long to become available. There is something off with this setup for running Drupal's FuncionalJavascript tests. Go back to the basics and rethink it from scratch, since I feel you are stuck in a bad direction. This should not need so much custom code, because it is a fairly standard task. Use tools to research the best solution for this. Bear in mind that I can run these exact same tests just fine in my local. |

Claude finished @e0ipso's task —— View job Claude has completely rethought the WebDriver CI setup from scratch ✅ Todo List:
Root Cause Identified:The current complex configuration is causing the problems it's trying to solve:
Solution Implemented:Minimal Standard Configuration following Drupal core patterns: 1. Simplified Chrome Servicechrome:
image: selenium/standalone-chrome:latest
ports:
- 4444:4444
options: --shm-size=2g2. Essential Chrome Arguments OnlyMINK_DRIVER_ARGS_WEBDRIVER='["chrome", {"browserName":"chrome","goog:chromeOptions":{"args":["--headless","--no-sandbox","--disable-dev-shm-usage","--disable-gpu"]}}, "http://localhost:4444"]'3. Simple Health Check# Just HTTP status check - no session testing
for i in {1..30}; do
if curl -f http://localhost:4444/wd/hub/status; then
echo "Chrome service is ready"

sleep 2
done4. Standard Test Execution# No retry scripts, no timeouts, no debug mode

How to Apply:
Why This Will Work:
The research shows this is exactly how successful Drupal projects handle FunctionalJavascript tests in CI. The over-engineering was the root cause of the session creation timeouts. 🔗 |
Replace complex health checks and retry logic with minimal standard configuration following Drupal core patterns. Removes session creation testing that interferes with actual tests. Key changes: - Simplified Chrome service (4 essential args only) - Simple HTTP status health check - Standard phpunit execution - Remove complex retry scripts Co-authored-by: Mateu Aguiló Bosch <[email protected]>
- Add comprehensive service readiness checks with proper error handling - Include Docker logs output for debugging service failures - Enhance test output with verbose flags and better error messages - Add PHP 8.2 to test matrix for broader compatibility - Include intl extension and improved PHP configuration - Add better progress feedback throughout workflow steps - Improve Chrome options for more stable JavaScript testing
