## Test Execution Workflow
|
||||
|
||||
Each test follows this pattern:
|
||||
|
||||
1. **Setup:** Clean state, activate venv
|
||||
2. **Execute:** Run test commands
|
||||
3. **Verify:** Check results and assertions
|
||||
4. **Cleanup:** Stop server, remove resources
|
||||
|
||||
## Running Individual Tests
|
||||
|
||||
```bash
|
||||
# Make test executable (if needed)
|
||||
chmod +x deploy/docker/tests/cli/basic/test_01_start_default.sh
|
||||
|
||||
# Run directly
|
||||
./deploy/docker/tests/cli/basic/test_01_start_default.sh
|
||||
|
||||
# Or use the test runner
|
||||
./run_tests.sh basic 01
|
||||
```
|
||||
|
||||
## Interpreting Results
|
||||
|
||||
### Success Output
|
||||
```
|
||||
✅ Test passed: [description]
|
||||
```
|
||||
|
||||
### Failure Output
|
||||
```
|
||||
❌ Test failed: [error message]
|
||||
```
|
||||
|
||||
### Warning Output
|
||||
```
|
||||
⚠️ Warning: [issue description]
|
||||
```
|
||||
|
||||
## Common Issues
|
||||
|
||||
### Docker Not Running
|
||||
```
|
||||
Error: Docker daemon not running
|
||||
Solution: Start Docker Desktop or Docker daemon
|
||||
```
|
||||
|
||||
### Port Already In Use
|
||||
```
|
||||
Error: Port 11235 is already in use
|
||||
Solution: Stop existing server or use different port
|
||||
```
|
||||
|
||||
### Virtual Environment Not Found
|
||||
```
|
||||
Warning: venv not found
|
||||
Solution: Create venv and activate it
|
||||
```
|
||||
|
||||
### Playwright Not Installed
|
||||
```
|
||||
Error: playwright module not found
|
||||
Solution: pip install playwright && playwright install chromium
|
||||
```
|
||||
|
||||
## Test Development
|
||||
|
||||
### Adding New Tests
|
||||
|
||||
1. **Choose category:** basic, advanced, resource, dashboard, or edge
|
||||
2. **Create test file:** Follow naming pattern `test_XX_description.sh`
|
||||
3. **Use template:**
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Test: [Description]
|
||||
# Expected: [What should happen]
|
||||
|
||||
set -e
|
||||
|
||||
echo "=== Test: [Name] ==="
|
||||
echo ""
|
||||
|
||||
source venv/bin/activate
|
||||
|
||||
# Cleanup
|
||||
crwl server stop 2>/dev/null || true
|
||||
sleep 2
|
||||
|
||||
# Test logic here
|
||||
|
||||
# Cleanup
|
||||
crwl server stop >/dev/null 2>&1
|
||||
|
||||
echo ""
|
||||
echo "✅ Test passed: [success message]"
|
||||
```
|
||||
|
||||
4. **Make executable:** `chmod +x test_XX_description.sh`
|
||||
5. **Test it:** `./test_XX_description.sh`
|
||||
6. **Add to runner:** Tests are auto-discovered by `run_tests.sh`
|
||||
|
||||
## CI/CD Integration
|
||||
|
||||
These tests can be integrated into CI/CD pipelines:
|
||||
|
||||
```yaml
|
||||
# Example GitHub Actions
|
||||
- name: Run CLI Tests
|
||||
run: |
|
||||
source venv/bin/activate
|
||||
cd deploy/docker/tests/cli
|
||||
./run_tests.sh all
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
- **Basic tests:** ~2-5 minutes total
|
||||
- **Advanced tests:** ~5-10 minutes total
|
||||
- **Resource tests:** ~10-15 minutes total (including 5-min stability test)
|
||||
- **Dashboard test:** ~3-5 minutes
|
||||
- **Edge case tests:** ~5-8 minutes total
|
||||
|
||||
**Full suite:** ~30-45 minutes
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Always cleanup:** Each test should cleanup after itself
|
||||
2. **Wait for readiness:** Add sleep after starting servers
|
||||
3. **Check health:** Verify health endpoint before assertions
|
||||
4. **Graceful failures:** Use `|| true` to continue on expected failures
|
||||
5. **Clear messages:** Output should clearly indicate what's being tested
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Tests Hanging
|
||||
- Check if Docker containers are stuck
|
||||
- Look for port conflicts
|
||||
- Verify network connectivity
|
||||
|
||||
### Intermittent Failures
|
||||
- Increase sleep durations for slower systems
|
||||
- Check system resources (memory, CPU)
|
||||
- Verify Docker has enough resources allocated
|
||||
|
||||
### All Tests Failing
|
||||
- Verify Docker is running: `docker ps`
|
||||
- Check CLI is installed: `which crwl`
|
||||
- Activate venv: `source venv/bin/activate`
|
||||
- Check server manager: `crwl server status`
|
||||
|
||||
## Contributing
|
||||
|
||||
When adding new tests:
|
||||
1. Follow existing naming conventions
|
||||
2. Add comprehensive documentation
|
||||
3. Test on clean system
|
||||
4. Update this README
|
||||
5. Ensure cleanup is robust
