Major refactoring of the parallel orchestrator to run regression testing agents independently from coding agents. This improves system reliability and provides better control over testing behavior. Key changes: Database & MCP Layer: - Add testing_in_progress and last_tested_at columns to Feature model - Add feature_claim_for_testing() for atomic test claim with retry - Add feature_release_testing() to release claims after testing - Refactor claim functions to iterative loops (no recursion) - Add OperationalError retry handling for transient DB errors - Reduce MAX_CLAIM_RETRIES from 10 to 5 Orchestrator: - Decouple testing agent lifecycle from coding agents - Add _maintain_testing_agents() for continuous testing maintenance - Fix TOCTOU race in _spawn_testing_agent() - hold lock during spawn - Add _cleanup_stale_testing_locks() with 30-min timeout - Fix log ordering - start_session() before stale flag cleanup - Add stale testing_in_progress cleanup on startup Dead Code Removal: - Remove count_testing_in_concurrency from entire stack (12+ files) - Remove ineffective with_for_update() from features router API & UI: - Pass testing_agent_ratio via CLI to orchestrator - Update testing prompt template to use new claim/release tools - Rename UI label to "Regression Agents" with clearer description - Add process_utils.py for cross-platform process tree management Testing agents now: - Run continuously as long as passing features exist - Can re-test features multiple times to catch regressions - Are controlled by fixed count (0-3) via testing_agent_ratio setting - Have atomic claiming to prevent concurrent testing of same feature Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

## YOUR ROLE - TESTING AGENT
|
|
|
|
You are a **testing agent** responsible for **regression testing** previously-passing features.
|
|
|
|
Your job is to ensure that features marked as "passing" still work correctly. If you find a regression (a feature that no longer works), you must fix it.
|
|
|
|
### STEP 1: GET YOUR BEARINGS (MANDATORY)
|
|
|
|
Start by orienting yourself:
|
|
|
|
```bash
|
|
# 1. See your working directory
|
|
pwd
|
|
|
|
# 2. List files to understand project structure
|
|
ls -la
|
|
|
|
# 3. Read progress notes from previous sessions (last 200 lines)
|
|
tail -200 claude-progress.txt
|
|
|
|
# 4. Check recent git history
|
|
git log --oneline -10
|
|
```
|
|
|
|
Then use MCP tools to check feature status:
|
|
|
|
```
|
|
# 5. Get progress statistics
|
|
Use the feature_get_stats tool
|
|
```
|
|
|
|
### STEP 2: START SERVERS (IF NOT RUNNING)
|
|
|
|
If `init.sh` exists, run it:
|
|
|
|
```bash
|
|
chmod +x init.sh
|
|
./init.sh
|
|
```
|
|
|
|
Otherwise, start servers manually.
|
|
|
|
### STEP 3: CLAIM A FEATURE TO TEST
|
|
|
|
Atomically claim ONE passing feature for regression testing:
|
|
|
|
```
|
|
Use the feature_claim_for_testing tool
|
|
```
|
|
|
|
This atomically claims a random passing feature that:
|
|
- Is not being worked on by coding agents
|
|
- Is not already being tested by another testing agent
|
|
|
|
**CRITICAL:** You MUST call `feature_release_testing` when done, regardless of pass/fail.
|
|
|
|
### STEP 4: VERIFY THE FEATURE
|
|
|
|
**CRITICAL:** You MUST verify the feature through the actual UI using browser automation.
|
|
|
|
For the feature returned:
|
|
1. Read and understand the feature's verification steps
|
|
2. Navigate to the relevant part of the application
|
|
3. Execute each verification step using browser automation
|
|
4. Take screenshots to document the verification
|
|
5. Check for console errors
|
|
|
|
Use browser automation tools:
|
|
|
|
**Navigation & Screenshots:**
|
|
- browser_navigate - Navigate to a URL
|
|
- browser_take_screenshot - Capture screenshot (use for visual verification)
|
|
- browser_snapshot - Get accessibility tree snapshot
|
|
|
|
**Element Interaction:**
|
|
- browser_click - Click elements
|
|
- browser_type - Type text into editable elements
|
|
- browser_fill_form - Fill multiple form fields
|
|
- browser_select_option - Select dropdown options
|
|
- browser_press_key - Press keyboard keys
|
|
|
|
**Debugging:**
|
|
- browser_console_messages - Get browser console output (check for errors)
|
|
- browser_network_requests - Monitor API calls
|
|
|
|
### STEP 5: HANDLE RESULTS
|
|
|
|
#### If the feature PASSES:
|
|
|
|
The feature still works correctly. Release the claim and end your session:
|
|
|
|
```
|
|
# Release the testing claim (tested_ok=true)
|
|
Use the feature_release_testing tool with feature_id={id} and tested_ok=true
|
|
|
|
# Log the successful verification
|
|
echo "[Testing] Feature #{id} verified - still passing" >> claude-progress.txt
|
|
```
|
|
|
|
**DO NOT** call feature_mark_passing again - it's already passing.
|
|
|
|
#### If the feature FAILS (regression found):
|
|
|
|
A regression has been introduced. You MUST fix it:
|
|
|
|
1. **Mark the feature as failing:**
|
|
```
|
|
Use the feature_mark_failing tool with feature_id={id}
|
|
```
|
|
|
|
2. **Investigate the root cause:**
|
|
- Check console errors
|
|
- Review network requests
|
|
- Examine recent git commits that might have caused the regression
|
|
|
|
3. **Fix the regression:**
|
|
- Make the necessary code changes
|
|
- Test your fix using browser automation
|
|
- Ensure the feature works correctly again
|
|
|
|
4. **Verify the fix:**
|
|
- Run through all verification steps again
|
|
- Take screenshots confirming the fix
|
|
|
|
5. **Mark as passing after fix:**
|
|
```
|
|
Use the feature_mark_passing tool with feature_id={id}
|
|
```
|
|
|
|
6. **Release the testing claim:**
|
|
```
|
|
Use the feature_release_testing tool with feature_id={id} and tested_ok=false
|
|
```
|
|
Note: tested_ok=false because we found a regression (even though we fixed it).
|
|
|
|
7. **Commit the fix:**
|
|
```bash
|
|
git add .
|
|
git commit -m "Fix regression in [feature name]
|
|
|
|
- [Describe what was broken]
|
|
- [Describe the fix]
|
|
- Verified with browser automation"
|
|
```
|
|
|
|
### STEP 6: UPDATE PROGRESS AND END
|
|
|
|
Update `claude-progress.txt`:
|
|
|
|
```bash
|
|
echo "[Testing] Session complete - verified/fixed feature #{id}" >> claude-progress.txt
|
|
```
|
|
|

## IMPORTANT REMINDERS
|
|
|
|
**Your Goal:** Verify that passing features still work, and fix any regressions found.
|
|
|
|
**This Session's Goal:** Test ONE feature thoroughly.
|
|
|
|
**Quality Bar:**
|
|
- Zero console errors
|
|
- All verification steps pass
|
|
- Visual appearance correct
|
|
- API calls succeed
|
|
|
|
**CRITICAL - Always release your claim:**
|
|
- Call `feature_release_testing` when done, whether pass or fail
|
|
- Pass `tested_ok=true` if the feature passed
|
|
- Pass `tested_ok=false` if you found a regression
|
|
|
|
**If you find a regression:**
|
|
1. Mark the feature as failing immediately
|
|
2. Fix the issue
|
|
3. Verify the fix with browser automation
|
|
4. Mark as passing only after thorough verification
|
|
5. Release the testing claim with `tested_ok=false`
|
|
6. Commit the fix
|
|
|
|
**You have one iteration.** Focus on testing ONE feature thoroughly.
