Resolve Failed E2E Test

Analyze a failed E2E test, fix the underlying issue, and verify the fix.

Variables

  • test_result: $ARGUMENTS - JSON object from /test-e2e command with failed test details

Input Format

Expects a JSON object from the /test-e2e command:

{
  "test_name": "Basic Query Execution",
  "status": "failed",
  "screenshots": [
    "screenshots/01_initial_state.png",
    "screenshots/02_query_input.png"
  ],
  "error": "Step 8 failed: Results did not appear within 5 seconds"
}

Instructions

1. Analyze the E2E Failure

Review the test result:

  • test_name: Which user journey failed
  • error: The specific step that failed
  • screenshots: Visual evidence of state before failure

Extract key information:

  • Which step number failed
  • What was the expected behavior
  • What actually happened
  • Visual clues from screenshots

2. Locate the Test Specification

Read the original test specification to understand:

  • The full user story
  • All test steps
  • Success criteria
  • Context around the failing step

3. Analyze Screenshots

Review captured screenshots to:

  • Understand application state at failure
  • Identify visual anomalies
  • Determine if UI elements are present/missing
  • Check for error messages on screen

4. Identify Root Cause

Common E2E failure causes:

SymptomLikely Cause
Element not foundSelector changed, slow load
Wrong textLogic error, data issue
TimeoutPerformance issue, missing element
Unexpected redirectAuth issue, error state
Missing elementComponent not rendering

5. Fix the Issue

Apply fixes based on root cause:

  • UI issue: Fix component rendering
  • Logic issue: Fix business logic
  • Timing issue: Add proper waits/loading states
  • Data issue: Fix data handling

IMPORTANT: Fix the application, not the test (unless test is genuinely incorrect).

6. Re-run E2E Test

Execute the original E2E test again:

/test-e2e {original_test_file}

Success criteria: Test status is "passed"

7. Verify No Regressions

Run related E2E tests to ensure fix doesn't break other flows.

Output Format

Report your resolution:

## E2E Resolution Complete

### Failure Analysis
- **Test**: {test_name}
- **Failed Step**: [step number and description]
- **Root Cause**: [what caused the failure]
- **Screenshot Evidence**: [observations from screenshots]

### Fix Applied
- **File(s) Modified**: [list of files]
- **Change Summary**: [brief description]
- **Type of Fix**: [UI/Logic/Performance/Data]

### Validation
- **E2E Test**: PASS
- **Related Tests**: PASS/FAIL
- **New Screenshots**: [paths to verification screenshots]

### Notes
[Any observations or recommendations]

Retry Logic

If the fix doesn't work:

  1. Review new screenshots for clues
  2. Consider timing/async issues
  3. Check for environment-specific problems
  4. Apply alternative fix

Maximum 2 retry attempts before escalating (E2E tests are slower).

Integration with Closed Loop

This command is the RESOLVE phase for E2E:

/test-e2e {spec} → [failure JSON] → /resolve-failed-e2e-test {result} → /test-e2e
                                                                            ↓
                                                                     [verify fix]
