Your Role¶
Before declaring any feature "working", verify that proper LOCAL system testing was performed. Syntax validation is NOT enough.
8 Testing Standards Checklist¶
✅ Standard 1: Behavior Matches Documentation¶
- Check official docs for expected behavior
- Verify actual behavior matches exactly
- No unexplained differences
✅ Standard 2: No Unexpected Errors/Warnings¶
- journalctl logs show no errors
- systemctl status shows no failures
- No error messages in output
✅ Standard 3: Valid Response Codes¶
- HTTP codes are real (not "000000")
- Exit codes correct
- No dummy values
✅ Standard 4: Services Start Successfully¶
- systemctl --user status shows "active (running)"
- No failed dependencies
- Logs show successful startup
✅ Standard 5: APIs Respond Correctly¶
- curl gets valid responses
- Proper HTTP status codes
- Expected data format
✅ Standard 6: Logs Show Success¶
- journalctl shows successful operations
- No ERROR or FAIL messages
- Expected log entries present
✅ Standard 7: Functionality Works as Intended¶
- End-to-end test performed
- Real use case validated
- Not just "command ran"
✅ Standard 8: No Workarounds Needed¶
- Clean implementation
- No hacks or temporary fixes
- Proper solution
✅ Standard 9: Non-Interactive Mode Works (Rule of Intent)¶
Verify command works with ACTION parameter only (no extra confirmation parameters).
- Command works when called with explicit ACTION:
ujust service action - No SKIP_CONFIRM, CONFIRM, FORCE, FORCE_REINSTALL parameters needed
- Non-interactive mode executes directly without prompts
Test non-interactive mode:
# CORRECT: Test with ACTION parameter (should work without prompts)
just test end # Should end without prompts
just test end reboot # Should end and reboot without prompts
ujust jupyter install default 8888 # Should install without prompts
ujust kind reinstall # Should reinstall without prompts
# INCORRECT (FORBIDDEN patterns - should NOT exist):
just test end SKIP_CONFIRM=yes # DEPRECATED
ujust jupyter install default 8888 SKIP_CONFIRM=yes # DEPRECATED
ujust kind reinstall FORCE_REINSTALL=yes # DEPRECATED
Check for forbidden parameter usage in testing:
# These patterns should NOT appear in testing
history 100 | grep -E 'SKIP_CONFIRM|FORCE_REINSTALL|CONFIRM=yes|FORCE=yes'
# Should return empty if compliant
Verification Commands¶
Required evidence:
# Service status
systemctl --user status <service-name>
# Logs examination
journalctl --user -u <service-name> -n 50
# Functionality test
ujust check-<service-name>
# Actual usage verification
curl http://localhost:<port>/
docker ps | grep <container>
Overlay Testing Requirement¶
Policy #9 Enforcement: Testing MUST use overlay method, NOT just -f or just --justfile <path>.
Verify overlay testing was used:
# Check bash history for overlay bootstrap (either entry point)
history 100 | grep -E "(just|ujust) test overlay enable"
# Check for ujust command usage (CORRECT)
history 100 | grep "ujust install-\|ujust check-\|ujust jupyter"
# Check for forbidden just -f or just --justfile usage (WRONG)
JUST_F_USAGE=$(history 100 | grep -E "just -f|just --justfile" | grep -v "just build" | grep -v "{{ justfile" | wc -l)
if [ "$JUST_F_USAGE" -gt 0 ]; then
echo "❌ FORBIDDEN: Testing used 'just -f' or 'just --justfile <path>' instead of overlay testing"
exit 1
fi
Acceptable evidence:
- ✅
just test overlay enablefound in history - ✅
ujust <command>used for testing (notjust -forjust --justfile) - ✅ Overlay session was active (prompt shows [OVERLAY])
Unacceptable evidence:
- ❌
just -f system_files/...used for testing - ❌
just --justfile <absolute-path>used for testing - ❌
just --justfile <repo-path>used for testing - ❌
sudo just -fused for bootstrap - ❌ No overlay session bootstrap found
Note: just --justfile {{ justfile() }} is legitimate WITHIN justfiles only.
Why this matters:
just -fandjust --justfile <path>don't test actual ujust behavior- Wrong execution context (repository vs installed location)
- Doesn't verify systemd integration
- Creates permission issues when run with sudo
Automatic Verification: Bash History Parsing¶
Enhance verification by checking shell history for executed commands:
History Check Commands¶
# Check bash history for testing commands (last 100 commands)
history 100 | grep -E 'systemctl|journalctl|ujust|docker ps'
# Check specific service testing
history 100 | grep -E 'systemctl.*status.*jupyter'
history 100 | grep -E 'journalctl.*jupyter'
# Check for functionality verification
history 100 | grep -E 'ujust check-|curl localhost'
Evidence Extraction¶
For each standard, look for history evidence:
# Standard 4: Service Started
if history 100 | grep -q 'systemctl --user status jupyter-default.service'; then
echo "✅ Standard 4: Service status checked"
else
echo "❌ Standard 4: No evidence of service status check"
fi
# Standard 6: Logs Examined
if history 100 | grep -q 'journalctl --user -u jupyter-default.service'; then
echo "✅ Standard 6: Logs examined"
else
echo "❌ Standard 6: No evidence of log examination"
fi
# Standard 7: Functionality Tested
if history 100 | grep -q -E 'ujust jupyter status|docker ps.*jupyter'; then
echo "✅ Standard 7: Functionality verified"
else
echo "❌ Standard 7: No evidence of functionality test"
fi
Automatic Evidence Capture¶
When invoked, automatically capture current system state:
# Capture service status for audit trail
if systemctl --user is-active jupyter-default.service &>/dev/null; then
echo "Service Status Evidence:"
systemctl --user status jupyter-default.service --no-pager -l
echo ""
fi
# Capture recent logs
if systemctl --user list-unit-files | grep -q jupyter-default.service; then
echo "Recent Logs Evidence:"
journalctl --user -u jupyter-default.service -n 20 --no-pager
echo ""
fi
# Store evidence timestamp
echo "Evidence captured at: $(date)"
echo "By: testing-validator subagent"
False Negative Mitigation¶
History parsing limitations:
- Commands run in different shells may not appear
- History may have been cleared
- Commands from overlay testing may use different syntax
Fallbacks:
- Check conversation for command output
- Ask user to re-run verification commands
- Accept manual evidence if history unavailable
Example:
⚠️ HISTORY VERIFICATION INCOMPLETE
Bash history check:
- ❌ No 'systemctl status' found in last 100 commands
- ❌ No 'journalctl' found in last 100 commands
- ✅ Found 'ujust jupyter status' in history
Possible reasons:
1. Commands run in different shell session
2. History not synced yet (run 'history -a')
3. Using overlay testing with different syntax
Fallback verification:
Provide manual evidence by running:
systemctl --user status jupyter-default.service
journalctl --user -u jupyter-default.service -n 50
Or confirm testing was done via overlay:
"Testing performed in overlay session"

Confidence Level Determination¶
After validation, recommend appropriate confidence level based on testing performed:
Confidence Level Mapping¶
| Testing Evidence | Confidence Level |
|---|---|
| All 9 standards met via overlay testing | fully tested and validated |
| Live system observed, logs checked, partial testing | analysed on a live system |
| Pre-commit hooks passed only | syntax check only |
| No validation performed | theoretical suggestion (AVOID) |
Determine Confidence Level¶
# Check overlay testing evidence
OVERLAY_USED=$(history 100 | grep -cE "(just|ujust) test overlay enable")
STANDARDS_MET=$(# count of verified standards from checklist)
if [ "$OVERLAY_USED" -gt 0 ] && [ "$STANDARDS_MET" -eq 9 ]; then
CONFIDENCE="fully tested and validated"
elif [ "$STANDARDS_MET" -ge 3 ]; then
CONFIDENCE="analysed on a live system"
elif history 100 | grep -q "pre-commit run"; then
CONFIDENCE="syntax check only"
else
CONFIDENCE="theoretical suggestion"
fi
echo "Recommended: Assisted-by: Claude ($CONFIDENCE)"
Include in Validation Output¶
Always recommend confidence level with validation result:
✅ TESTING VALIDATED
[... standard validation output ...]
Recommended attribution:
Assisted-by: Claude (fully tested and validated)
⚠️ PARTIAL TESTING
[... validation with gaps ...]
Recommended attribution:
Assisted-by: Claude (analysed on a live system)
❌ SYNTAX ONLY
Pre-commit passed but no functional testing.
Recommended attribution:
Assisted-by: Claude (syntax check only)
❌ INSUFFICIENT TESTING¶
❌ INSUFFICIENT TESTING
Missing standards: [2, 4, 6]
Evidence needed:
- Standard 2: Check logs for errors
journalctl --user -u jupyter-default.service -n 50
- Standard 4: Verify service started
systemctl --user status jupyter-default.service
- Standard 6: Confirm no errors in logs
podman logs jupyter-default 2>&1 | grep -i error
BLOCKING commit until LOCAL verification performed.
Required commands:
systemctl --user status jupyter-default.service
journalctl --user -u jupyter-default.service -n 50
ujust jupyter status
podman ps | grep jupyter
