+## Continuous Integration
+
+### Automated Testing
+
+To run tests automatically on each deployment:
+
+```bash
+# Example CI script
+#!/bin/bash
+
+echo "Running System Hub Profile Tests..."
+
+# Deploy to test router
+./deploy.sh test-router
+
+# Run tests via SSH
+ssh root@test-router "cd /usr/share/system-hub/tests && ./test-profiles.sh"
+TEST_RESULT=$?
+
+ssh root@test-router "cd /usr/share/system-hub/tests/integration && ./test-diagnostic-workflow.sh"
+INTEGRATION_RESULT=$?
+
+# Check results
+if [ $TEST_RESULT -eq 0 ] && [ $INTEGRATION_RESULT -eq 0 ]; then
+    echo "✅ All automated tests passed"
+    exit 0
+else
+    echo "❌ Tests failed"
+    exit 1
+fi
+```
+
+---
+
+## Troubleshooting
+
+### Unit Tests Failing
+
+**Problem**: `ubus call` commands fail
+
+**Solutions**:
+- Verify rpcd is running: `/etc/init.d/rpcd status`
+- Restart rpcd: `/etc/init.d/rpcd restart`
+- Check ACL permissions are deployed
+- Verify user has luci-app-system-hub ACL
+
+### Integration Tests Failing
+
+**Problem**: Archive creation fails
+
+**Solutions**:
+- Check `/tmp/system-hub/diagnostics/` directory exists
+- Verify disk space: `df -h`
+- Check system logs: `logread | grep system-hub`
+
+### Frontend Tests Failing
+
+**Problem**: Profile buttons not found
+
+**Solutions**:
+- Clear browser cache (Ctrl+Shift+R)
+- Verify diagnostics.js is deployed
+- Check browser console for JavaScript errors
+- Ensure LuCI cache is cleared: `rm -rf /tmp/luci-*`
+
+### Manual Tests Failing
+
+**Problem**: UI doesn't match expected results
+
+**Solutions**:
+- Logout and login again (ACL refresh)
+- Clear browser cache completely
+- Verify all files deployed correctly
+- Check browser compatibility (use latest Chrome/Firefox)
+
+---
+
+## Test Maintenance
+
+### Adding New Tests
+
+1. **Unit Tests**: Add new test functions to `test-profiles.sh`
+2. **Integration Tests**: Create new script in `integration/`
+3. **Frontend Tests**: Add new test functions to `test-diagnostics-ui.js`
+4. **Manual Tests**: Add new test case to `MANUAL_TESTS.md`
+
+### Updating Tests
+
+When adding new profiles or features:
+1. Update test expectations (profile count, names, etc.)
+2. Add tests for new functionality
+3. Run full test suite to ensure no regressions
+4. Update this README if test procedures change
+
+---
+
+## Contributing
+
+When contributing tests:
+- Follow existing patterns and conventions
+- Add comments explaining what is being tested
+- Include both positive and negative test cases
+- Update documentation
+- Test on actual hardware before submitting
+
+---
+
+## Support
+
+For questions about testing:
+- Check test output for specific error messages
+- Review router logs: `logread`
+- Check RPC backend: `ubus call luci.system-hub list`
+- Verify deployment: `opkg list-installed | grep system-hub`
