🔧 How It Works

Example: "Open Overworld editor"

Step 1: Parse Prompt

TestWorkflowGenerator generator;
auto workflow = generator.GenerateWorkflow("Open Overworld editor");
// Result:
// - Click(button:Overworld)
// - Wait(window_visible:Overworld Editor, 5000ms)

Step 2: Execute Workflow

GuiAutomationClient client("localhost:50052");
client.Connect();

// Execute each step
auto result1 = client.Click("button:Overworld");  // 125ms
auto result2 = client.Wait("window_visible:Overworld Editor");  // 1250ms
// Total: 1375ms

Step 3: Report Results

[1/2] Click(button:Overworld) ... ✓ (125ms)
[2/2] Wait(window_visible:Overworld Editor, 5000ms) ... ✓ (1250ms)

✅ Test passed in 1375ms

🚀 How to Use

Build with gRPC Support

# Configure
cmake -B build-grpc-test -DYAZE_WITH_GRPC=ON

# Build
cmake --build build-grpc-test --target yaze -j$(sysctl -n hw.ncpu)
cmake --build build-grpc-test --target z3ed -j$(sysctl -n hw.ncpu)

Run Automated GUI Tests

# Terminal 1: Start YAZE with test harness
./build-grpc-test/bin/yaze.app/Contents/MacOS/yaze \
  --enable_test_harness \
  --test_harness_port=50052 \
  --rom_file=assets/zelda3.sfc &

# Terminal 2: Run test command
./build-grpc-test/bin/z3ed agent test \
  --prompt "Open Overworld editor"

Supported Prompts

1. Open Editor

   z3ed agent test --prompt "Open Overworld editor"
   

2. Open and Verify

   z3ed agent test --prompt "Open Dungeon editor and verify it loads"
   

3. Click Button

   z3ed agent test --prompt "Click Open ROM button"
   

4. Type Input

   z3ed agent test --prompt "Type 'zelda3.sfc' in filename input"

📊 Current Status

✅ Complete

• IT-01: ImGuiTestHarness gRPC service (11 hours)
• IT-02: CLI agent test command (4 hours) ← Today's Work
• AW-01/02/03: Proposal infrastructure + GUI
• Phase 6: Resource catalog

📋 Next (Priority 1)

• E2E Validation: Test all systems together (2-3 hours)
• Follow E2E_VALIDATION_GUIDE.md checklist
• Validate 4 phases:
  1. Automated test script
  2. Manual proposal workflow
  3. Real widget automation
  4. Documentation updates

🔮 Future (Priority 3)

• AW-04: Policy evaluation framework (6-8 hours)
• YAML-based constraints for proposal acceptance
• Integration with ProposalDrawer UI

🎓 Key Design Decisions

1. Why gRPC Client Wrapper?

Problem: CLI needs to automate GUI without duplicating logic
Solution: Thin wrapper around gRPC service
Benefits:

• Reuses existing test harness infrastructure
• Type-safe C++ API
• Proper error handling with absl::Status
• Easy to extend

2. Why Natural Language Parsing?

Problem: Users want high-level commands, not low-level RPC calls
Solution: Pattern matching with regex
Benefits:

• Intuitive user interface
• Extensible pattern system
• Helpful error messages
• Easy to add new patterns

3. Why Separate TestWorkflow struct?

Problem: Need to plan before executing
Solution: Generate workflow, then execute
Benefits:

• Can show plan before running
• Enable dry-run mode
• Better error messages
• Easier testing

Time Investment

• Design: 1 hour (architecture + interfaces)
• Implementation: 2 hours (coding + debugging)
• Documentation: 1 hour (guides + comments)
• Total: 4 hours

🐛 Known Limitations

Natural Language Parser

• Limited to 4 pattern types (easily extensible)
• Case-sensitive widget names (intentional for precision)
• No multi-step conditionals (future enhancement)

Widget Discovery

• Requires exact label matches
• No fuzzy matching (could add)
• No widget introspection (limitation of ImGui)

Error Handling

• Basic error messages (could be more descriptive)
• No suggestions on typos (could add Levenshtein distance)
• No recovery from failed steps (could add retry logic)

Platform Support

• gRPC test harness: macOS/Linux only
• Windows: Manual testing required
• Conditional compilation: YAZE_WITH_GRPC required

💡 Lessons Learned

What Went Well

1. Clear Architecture: GuiAutomationClient + TestWorkflowGenerator separation
2. Incremental Development: Build → Test → Document
3. Comprehensive Docs: E2E guide will save hours of debugging
4. Code Reuse: Leveraged existing IT-01 infrastructure

What Could Be Improved

1. More Pattern Types: Only 4 patterns, could add more
2. Better Error Messages: Could include suggestions
3. Widget Discovery: No introspection, must know exact names
4. Cross-Platform: Windows support missing

Future Considerations

1. LLM Integration: Generate patterns from examples
2. Visual Testing: Screenshot comparison
3. Performance: Parallel step execution
4. Debugging: Better logging and traces
