Complete Workflow Example

1. Start Test Harness

  --enable_test_harness \
  --test_harness_port=50052 \
  --rom_file=assets/zelda3.sfc &

2. Automated GUI Testing (NEW)

# Click button
grpcurl -plaintext -import-path src/app/core/proto -proto imgui_test_harness.proto \
  -d '{"target":"button:Overworld","type":"LEFT"}' \
  127.0.0.1:50052 yaze.test.ImGuiTestHarness/Click

# Wait for window
grpcurl -plaintext -import-path src/app/core/proto -proto imgui_test_harness.proto \
  -d '{"condition":"window_visible:Overworld Editor","timeout_ms":5000}' \
  127.0.0.1:50052 yaze.test.ImGuiTestHarness/Wait

# Assert window visible
grpcurl -plaintext -import-path src/app/core/proto -proto imgui_test_harness.proto \
  -d '{"condition":"visible:Overworld Editor"}' \
  127.0.0.1:50052 yaze.test.ImGuiTestHarness/Assert

3. Run E2E Test Script (NEW)

./scripts/test_harness_e2e.sh

Output:

=== ImGuiTestHarness E2E Test ===

✓ Server started successfully

Test 1: Ping (Health Check)
✓ PASSED

Test 2: Click (Button)
✓ PASSED

Test 3: Type (Text Input)
✓ PASSED

Test 4: Wait (Window Visible)
✓ PASSED

Test 5: Assert (Window Visible)
✓ PASSED

=== Test Summary ===
Tests Run:    6
Tests Passed: 6
Tests Failed: 0

All tests passed!

Active Priorities

Priority 1: End-to-End Workflow Testing (Oct 3-4) 📋 NEXT

1. Manual Testing:

   • Start YAZE with test harness
   • Test all RPCs with real YAZE widgets
   • Validate error handling
   • Document edge cases

2. Workflow Validation:

   • Test complete workflows (Click → Wait → Assert)
   • Test text input workflows (Click → Type → Assert)
   • Test timeout scenarios
   • Test widget not found scenarios

Priority 2: CLI Agent Integration (Oct 5-8)

1. Create z3ed agent test Command:

   • Parse natural language prompts
   • Generate RPC call sequences
   • Execute workflow via gRPC
   • Capture results and screenshots

2. Example:

   z3ed agent test --prompt "Open Overworld editor and verify it loads" \
     --rom zelda3.sfc
   
   # Generated workflow:
   # 1. Click "button:Overworld"
   # 2. Wait "window_visible:Overworld Editor" (5s)
   # 3. Assert "visible:Overworld Editor"
   # 4. Screenshot "full"
   

Priority 3: Policy Evaluation Framework (Oct 9-12)

1. YAML Policy Configuration:

   • Define constraint schemas
   • Implement PolicyEvaluator service
   • Integrate with ProposalDrawer

2. Policy Types:

   • Change constraints (byte limits, allowed banks)
   • Test requirements (pass rate, coverage)
   • Review requirements (approval count)

---

Known Limitations

Non-Blocking Issues

1. ProposalDrawer UX:

   • No keyboard navigation
   • Large diffs truncated at 1000 lines

2. Test Harness:

   • Screenshot RPC not implemented
   • text_contains assertion uses placeholder
   • Windows/Linux testing pending

3. Test Coverage:

   • Need end-to-end workflow validation
   • Need real widget interaction testing

Future Enhancements

1. Screenshot capture with image encoding
2. Advanced text retrieval for assertions
3. Keyboard shortcut automation
4. Recording/playback of test sequences
