|
|
|
|
## 📋 Work Completed
|
|
|
|
### 1. Worker Test Executor Implementation
|
|
|
|
**File**: `crates/worker/src/test_executor.rs` (489 lines)
|
|
|
|
Created a comprehensive test executor module with:
|
|
|
|
- **TestExecutor struct**: Core executor for running pack tests
|
|
- **Configuration parsing**: Reads test config from pack.yaml
|
|
- **Multi-runtime support**:
|
|
- Shell scripts (`script` type)
|
|
- Python unittest (`unittest` type)
|
|
- Pytest (`pytest` type - ready for future)
|
|
- **Test suite execution**: Runs each runner type independently
|
|
- **Command execution**: Async command execution with timeout support
|
|
- **Result aggregation**: Combines results from multiple test suites
|
|
|
|
**Key Features**:
|
|
- Timeout handling (configurable per runner)
|
|
- Working directory management (runs tests from pack directory)
|
|
- Exit code detection
|
|
- Stdout/stderr capture
|
|
- Duration tracking
|
|
|
|
### 2. Simple Output Parser
|
|
|
|
**Implementation**: Part of `test_executor.rs`
|
|
|
|
Implemented `parse_simple_output()` method that:
|
|
- Extracts test counts from output text
|
|
- Parses patterns: "Total Tests:", "Passed:", "Failed:", "Skipped:"
|
|
- Falls back to exit code if parsing fails
|
|
- Creates structured `TestSuiteResult` with test cases
|
|
- Handles both success and failure scenarios
|
|
|
|
**Test Coverage**:
|
|
- Unit tests for number extraction
|
|
- Unit tests for output parsing
|
|
- Unit tests for failure scenarios
|
|
|
|
### 3. CLI Pack Test Command
|
|
|
|
**Files Modified**:
|
|
- `crates/cli/src/commands/pack.rs`
|
|
- `crates/cli/Cargo.toml` (added worker dependency)
|
|
- `crates/worker/src/lib.rs` (exported test executor)
|
|
|
|
**Command Syntax**:
|
|
```bash
|
|
attune pack test <pack> # Test a pack
|
|
attune pack test <pack> --verbose # Show verbose output
|
|
attune pack test <pack> --detailed # Show detailed test results
|
|
attune pack test <pack> --output json # JSON output
|
|
attune pack test <pack> --output yaml # YAML output
|
|
```
|
|
|
|
**Features**:
|
|
- Supports both local pack directories and installed packs
|
|
- Loads and parses pack.yaml configuration
|
|
- Validates testing is enabled
|
|
- Executes test executor
|
|
- Multiple output formats (table, JSON, YAML)
|
|
- Colored output with emoji indicators
|
|
- Exit code handling (fails if tests fail)
|
|
- Verbose mode shows individual test cases
|
|
- Detailed mode shows stdout/stderr (truncated)
|
|
|
|
### 4. End-to-End Testing
|
|
|
|
**Test Execution**:
|
|
```bash
|
|
./target/debug/attune pack test packs/core
|
|
```
|
|
|
|
**Results**:
|
|
- ✅ Shell tests: 36/36 passed (12.3s)
|
|
- ✅ Python tests: 38 tests, 36 passed, 2 skipped (13.0s)
|
|
- ✅ Total: 2/2 test suites passed (100% pass rate)
|
|
- ✅ Total duration: ~26 seconds
|
|
|
|
**Output Formats Tested**:
|
|
- ✅ Table format (default, colored)
|
|
- ✅ JSON format (structured data)
|
|
- ✅ YAML format
|
|
- ✅ Verbose mode (shows test case details)
|
|
- ✅ Detailed mode (shows stdout/stderr)
|

## 🔧 Technical Implementation Details
|
|
|
|
### Test Executor Architecture
|
|
|
|
```rust
|
|
TestExecutor
|
|
├── execute_pack_tests() // Main entry point
|
|
│ ├── Load pack configuration
|
|
│ ├── Validate pack directory
|
|
│ └── For each runner:
|
|
│ └── execute_test_suite()
|
|
│ ├── Resolve entry point
|
|
│ ├── Build command
|
|
│ ├── run_command()
|
|
│ │ ├── Spawn process
|
|
│ │ ├── Wait with timeout
|
|
│ │ └── Capture output
|
|
│ └── parse_simple_output()
|
|
│ ├── Extract counts
|
|
│ └── Build TestSuiteResult
|
|
└── Aggregate results
|
|
```
|
|
|
|
### Data Flow

|
|
```
|
|
|
|
### Working Directory Fix
|
|
|
|
**Issue**: Initial implementation used full paths from wrong working directory
|
|
**Solution**:
|
|
- Set working directory to pack directory
|
|
- Use relative paths for entry points
|
|
- Strip prefix from full paths
|
|
|
|
**Before**: `/bin/bash packs/core/tests/run_tests.sh` (from attune dir)
|
|
**After**: `/bin/bash tests/run_tests.sh` (from packs/core dir)
|

## 🎓 Key Learnings
|
|
|
|
1. **Error Handling**: The `Error::NotFound` variant is a struct, not a tuple. Must use `Error::not_found()` helper.
|
|
|
|
2. **Working Directory**: Commands must be executed from the correct working directory. Use relative paths from that directory.
|
|
|
|
3. **Async Process Execution**: Tokio's `Command` API provides clean async subprocess execution with timeout support.
|
|
|
|
4. **Test Output Parsing**: Simple line-by-line parsing is sufficient for basic test runners. More complex parsers (JUnit, TAP) can be added later.
|
|
|
|
5. **CLI Output Formats**: Supporting multiple output formats (table, JSON, YAML) makes the tool scriptable and human-friendly.
|

### 4. **API Endpoints Implementation**
|
|
|
|
**Files**: `crates/api/src/routes/packs.rs`, `crates/api/Cargo.toml`
|
|
|
|
Successfully added three new REST API endpoints:
|
|
|
|
1. **POST `/api/v1/packs/{ref}/test`**
|
|
- Executes all tests for a pack
|
|
- Loads pack.yaml configuration
|
|
- Runs test executor
|
|
- Stores results in database
|
|
- Returns structured test results
|
|
|
|
2. **GET `/api/v1/packs/{ref}/tests`**
|
|
- Retrieves paginated test history
|
|
- Ordered by execution time (newest first)
|
|
- Supports pagination (page, limit)
|
|
|
|
3. **GET `/api/v1/packs/{ref}/tests/latest`**
|
|
- Returns most recent test execution
|
|
- Useful for monitoring and dashboards
|
|
|
|
**Features**:
|
|
- Authentication required (Bearer token)
|
|
- OpenAPI/Swagger documentation
|
|
