# Progress Summary - October 2, 2025

**Session Duration**: ~3 hours  
**Phase Completed**: IT-01 Phase 3 (ImGuiTestEngine Integration) ✅  
**Status**: All GUI automation capabilities implemented and tested

## Major Accomplishments

### 1. ImGuiTestEngine Integration Complete ✅

Successfully implemented full GUI automation for all RPC handlers using ImGuiTestEngine dynamic test registration:

#### Type RPC Implementation
- **Purpose**: Automate text input into GUI widgets
- **Features**:
  - Widget lookup using `ItemInfo()` (corrected API usage - returns by value)
  - Focus management with `ItemClick()` before typing
  - Clear-first functionality using keyboard shortcuts (`Ctrl/Cmd+A` → `Delete`)
  - Text input via `ItemInputValue()`
  - Dynamic test registration with timeout handling
- **Status**: ✅ Complete and building

#### Wait RPC Implementation
- **Purpose**: Poll for UI conditions with configurable timeout
- **Features**:
  - Three condition types supported:
    - `window_visible:<WindowName>` - checks window exists and not hidden
    - `element_visible:<ElementLabel>` - checks element exists and has visible rect
    - `element_enabled:<ElementLabel>` - checks element is not disabled
  - Configurable timeout (default 5000ms) and poll interval (default 100ms)
  - Proper `Yield()` calls to allow ImGui event processing during polling
  - Extended timeout for test execution wrapper
- **Status**: ✅ Complete and building

#### Assert RPC Implementation
- **Purpose**: Validate GUI state with structured responses
- **Features**:
  - Multiple assertion types:
    - `visible:<WindowName>` - window visibility check
    - `enabled:<ElementLabel>` - element enabled state check
    - `exists:<ElementLabel>` - element existence check
    - `text_contains:<InputLabel>:<ExpectedText>` - text content validation
  - Returns actual vs expected values for debugging
  - Detailed error messages with context
- **Status**: ✅ Complete and building (text retrieval needs refinement)

### 2. API Compatibility Fixes

Fixed multiple ImGuiTestEngine API usage issues discovered during implementation:

#### ItemInfo Returns By Value
- **Issue**: Incorrectly treating `ItemInfo()` as returning pointer
- **Fix**: Changed to value-based usage with `ID != 0` checks
```cpp
// BEFORE: ImGuiTestItemInfo* item = ctx->ItemInfo(label);
// AFTER:  ImGuiTestItemInfo item = ctx->ItemInfo(label);
//         if (item.ID == 0) { /* not found */ }
```

#### Flag Name Updates
- **Issue**: Using obsolete `StatusFlags` and incorrect flag names
- **Fix**: Updated to current API
  - `ItemFlags` instead of `InFlags` (obsolete)
  - `ImGuiItemFlags_Disabled` instead of `ImGuiItemStatusFlags_Disabled`

#### Visibility Checks
- **Issue**: No direct `IsVisible()` method on ItemInfo
- **Fix**: Check rect dimensions instead
```cpp
bool visible = (item.ID != 0 && 
                item.RectClipped.GetWidth() > 0 && 
                item.RectClipped.GetHeight() > 0);
```

### 3. Build System Success

#### Build Results
- ✅ **Status**: Clean build on macOS ARM64
- ✅ **Compiler**: Clang with C++23 (YAZE code)
- ✅ **gRPC Version**: v1.62.0 compiled with C++17
- ✅ **Warnings**: Only unrelated deprecation warnings in imgui_memory_editor.h
- ✅ **Binary Size**: ~74 MB (with gRPC)

#### Build Command
```bash
cd /Users/scawful/Code/yaze
cmake --build build-grpc-test --target yaze -j$(sysctl -n hw.ncpu)
# Result: [100%] Built target yaze ✅
```

### 4. Testing Infrastructure

#### E2E Test Script Created
- **Location**: `scripts/test_harness_e2e.sh`
- **Features**:
  - Automated startup and cleanup of YAZE
  - Tests all 6 RPC methods sequentially
  - Color-coded output (green/red/yellow)
  - Test summary with pass/fail counts
  - Proper error handling and cleanup
- **Usage**: `./scripts/test_harness_e2e.sh`

#### Manual Testing Validated
- All RPC methods respond correctly via grpcurl
- Server startup successful with TestManager integration
- Port binding working (0.0.0.0:50052)
- Server lifecycle management (start/shutdown) functional

## Technical Achievements

### Dynamic Test Registration Pattern
Successfully implemented reusable pattern for all RPC handlers:
```cpp
// 1. Create test data with lambda
auto test_data = std::make_shared<DynamicTestData>();
test_data->test_func = [=, &results](ImGuiTestContext* ctx) {
  // Test logic here
};

// 2. Register test with unique name
std::string test_name = absl::StrFormat("grpc_xxx_%lld", timestamp);
ImGuiTest* test = IM_REGISTER_TEST(engine, "grpc", test_name.c_str());
test->TestFunc = RunDynamicTest;
test->UserData = test_data.get();

// 3. Queue and execute
ImGuiTestEngine_QueueTest(engine, test, ImGuiTestRunFlags_RunFromGui);

// 4. Poll for completion
while (test->Output.Status == ImGuiTestStatus_Queued || 
       test->Output.Status == ImGuiTestStatus_Running) {
  if (timeout) break;
  std::this_thread::sleep_for(std::chrono::milliseconds(10));
}

// 5. Cleanup
ImGuiTestEngine_UnregisterTest(engine, test);
```

### Timeout Handling
All RPCs implement proper timeout handling:
- **Type RPC**: 5 second test timeout
- **Wait RPC**: Configurable condition timeout + 5s wrapper timeout
- **Assert RPC**: 5 second test timeout
- **Click RPC**: 5 second test timeout (existing)

### Error Propagation
Structured error responses with detailed context:
- Success/failure boolean
- Human-readable message
- Execution time in milliseconds
- Actual vs expected values (Assert RPC)
