Subject: [PATCH 2/2] [tests] Fix ChromeDriver timeouts and restore removed
Selenium tests
This commit addresses the random hangs and crashes in Selenium tests
with websockets on GitHub Actions (issue #582).
Changes:
- Added explicit timeout configuration to ChromeDriver (page load, script, implicit wait)
- Increased WebDriverWait timeout values for CI environments
- Added configurable timeout parameters (webdriver_wait_timeout, websocket_wait_timeout)
- Replaced time.sleep() with explicit WebDriverWait in alert handling
- Restored test_websocket_marker for real-time websocket communication
- Restored test_topology_graph for network topology visualization
- Restored test_create_prefix_users for RADIUS batch operations
- Added comprehensive documentation in tests/SELENIUM_FIXES.md
All restored tests now use increased timeouts and improved error handling
to prevent ChromeDriver hangs and ReadTimeoutError exceptions.

+# Selenium Test Fixes for ChromeDriver Timeouts
+
+## Problem Description
+
+Selenium tests were intermittently failing on GitHub Actions with `ReadTimeoutError` exceptions. The ChromeDriver process would hang without providing feedback, causing tests to timeout and fail. This particularly affected tests involving websockets and complex page interactions.
+
+## Root Causes
+
+1. **ChromeDriver Hangs**: ChromeDriver can hang in headless mode, especially in resource-constrained CI environments
+2. **Insufficient Timeouts**: Default timeout values (3 seconds) were too short for complex operations
+3. **WebSocket Delays**: WebSocket communication requires more time to establish connections and propagate updates
+4. **Hard-coded Waits**: Use of `time.sleep()` instead of explicit waits led to timing issues
+
+## Solutions Implemented
+
+### 1. WebDriver Timeout Configuration (`tests/utils.py`)
+
+Added explicit timeout configuration to ChromeDriver instances:
+
+```python
+def get_chrome_webdriver(cls):
+ driver = super().get_chrome_webdriver()
+ driver.set_page_load_timeout(60) # Max time for page loads
+ driver.set_script_timeout(60) # Max time for async scripts
+ driver.implicitly_wait(10) # Element search timeout
+ return driver
+```
+
+### 2. Configurable Timeout Values (`tests/config.json`)
+
+Added configurable timeout parameters:
+
+- `webdriver_wait_timeout`: 20 seconds (for general WebDriverWait calls)
+- `websocket_wait_timeout`: 30 seconds (for websocket-related operations)
+
+### 3. Improved Alert Handling (`tests/utils.py`)
+
+Replaced hard-coded `time.sleep(2)` with explicit wait:
+
+```python
+def _ignore_location_alert(self, driver=None):
+ try:
+ WebDriverWait(driver, 5).until(EC.alert_is_present())
+ # Handle alert...
+ except (NoAlertPresentException, Exception):
+ pass # Timeout or no alert is okay
+```
+
+### 4. Dynamic Timeout Usage in Tests
+
+Tests now use configurable timeouts instead of hard-coded values:
+
+```python
+timeout = self.config.get("webdriver_wait_timeout", 10)
+WebDriverWait(self.base_driver, timeout).until(...)
+```
+
+### 5. Restored Tests with Improvements
+
+Re-added the following tests that were removed in PR #581:
+
+- `test_websocket_marker`: Tests real-time location updates via websockets
+- `test_topology_graph`: Tests network topology visualization
+- `test_create_prefix_users`: Tests RADIUS batch user creation with PDF generation
+
+All restored tests include:
+- Increased timeout values
+- Explicit waits instead of sleeps
+- Better error handling
+
+## Testing Recommendations
+
+### Local Testing
+
+```bash
+cd /opt/openwisp/docker-openwisp
+make develop-pythontests
+```
+
+### CI Testing
+
+The CI workflow already includes retry logic (5 attempts with 30-second delays). With these fixes, tests should pass consistently on the first attempt.
+
+### Timeout Tuning
+
+If tests still timeout in CI:
+
+1. Increase values in `tests/config.json`:
+ - `webdriver_wait_timeout`: Increase for general operations
+ - `websocket_wait_timeout`: Increase for websocket tests
+
+2. Check ChromeDriver version compatibility
+3. Review GitHub Actions runner resource constraints
+
+## Known Issues and Workarounds
+
+### Issue: ChromeDriver Still Hangs
+
+**Workaround**: The CI workflow uses a retry mechanism. If hangs persist:
+
+1. Check ChromeDriver and Selenium versions for compatibility
+2. Consider adding `--disable-dev-shm-usage` Chrome option
+3. Verify headless mode is properly configured
+
+### Issue: WebSocket Tests Fail Intermittently
+
+**Workaround**: WebSocket connections depend on multiple services:
+
+1. Ensure all containers are healthy before tests
+2. Check Redis container status (used for channels)
+3. Verify WebSocket container logs for connection issues

+
+## Maintenance Notes
+
+When adding new Selenium tests:
+
+1. Use `self.config.get('webdriver_wait_timeout', 10)` for standard waits
+2. Use `self.config.get('websocket_wait_timeout', 30)` for websocket operations
+3. Always use explicit waits (`WebDriverWait`) instead of `time.sleep()`
+4. Test locally with `SELENIUM_HEADLESS=1` to simulate CI environment
+5. Add appropriate timeout parameters to `find_elements()` calls for dynamic content
