|
||||
|
||||
## 🔧 How It Works
|
||||
|
||||
### Example: "Open Overworld editor"
|
||||
|
||||
**Step 1: Parse Prompt**
|
||||
```cpp
|
||||
TestWorkflowGenerator generator;
|
||||
auto workflow = generator.GenerateWorkflow("Open Overworld editor");
|
||||
// Result:
|
||||
// - Click(button:Overworld)
|
||||
// - Wait(window_visible:Overworld Editor, 5000ms)
|
||||
```
|
||||
|
||||
**Step 2: Execute Workflow**
|
||||
```cpp
|
||||
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
|
||||
|
||||
```bash
|
||||
# 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
|
||||
|
||||
```bash
|
||||
# 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**
|
||||
```bash
|
||||
z3ed agent test --prompt "Open Overworld editor"
|
||||
```
|
||||
|
||||
2. **Open and Verify**
|
||||
```bash
|
||||
z3ed agent test --prompt "Open Dungeon editor and verify it loads"
|
||||
```
|
||||
|
||||
3. **Click Button**
|
||||
```bash
|
||||
z3ed agent test --prompt "Click Open ROM button"
|
||||
```
|
||||
|
||||
4. **Type Input**
|
||||
```bash
|
||||
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
|
||||
|
||||

|
||||
|
||||
## 📈 Metrics
|
||||
|
||||
### Code Quality
|
||||
- **New Lines**: ~1,350 (660 implementation + 690 documentation)
|
||||
- **Files Created**: 7 (4 source + 1 build + 2 docs)
|
||||
- **Files Modified**: 2 (agent.cc + CMakeLists.txt)
|
||||
- **Test Coverage**: E2E test script + validation guide
|
||||
|
||||
### Time Investment
|
||||
- **Design**: 1 hour (architecture + interfaces)
|
||||
- **Implementation**: 2 hours (coding + debugging)
|
||||
- **Documentation**: 1 hour (guides + comments)
|
||||
- **Total**: 4 hours
|
||||
|
||||
### Functionality
|
||||
- **RPC Methods**: 6 wrapped (Ping, Click, Type, Wait, Assert, Screenshot)
|
||||
- **Pattern Types**: 4 supported (Open, OpenVerify, Type, Click)
|
||||
- **Command Flags**: 4 supported (prompt, host, port, timeout)
|
||||
|
||||

|
||||
|
||||
## 🐛 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
