+# Datest Implementation Summary
+
+## 🎯 Overview
+
+Successfully implemented all three phases of the Datest MVP - a Dana-native testing framework that integrates with the existing Dana runtime and pytest infrastructure.
+
+## ✅ Completed Phases
+
+### Phase 1: Foundation ✅
+- **Basic file discovery** (`datest/discovery.py`)
+- **Dana runtime integration** (`datest/executor.py`) 
+- **Result reporting** (`datest/reporter.py`)
+- **CLI structure** (`datest/cli.py`)
+- **Test fixtures** (`tests/fixtures/`)
+- **Unit tests** (`tests/unit/test_discovery.py`)
+
+### Phase 2: Dana Integration ✅
+- **Data models** (`datest/models.py`)
+  - `DanaTestFile`, `DanaAssertion`, `DanaTestResult`
+- **Assertion parsing** (`datest/assertions.py`)
+  - Parses Dana output for assertions, logs, and errors
+  - Supports both text and JSON output formats
+- **Enhanced executor** with assertion parsing
+- **Improved reporter** with structured output
+- **Comprehensive unit tests** for all new modules
+- **Integration tests** (`tests/integration/`)
+
+### Phase 3: Polish & Integration ✅
+- **pytest plugin** (`datest/pytest_plugin.py`)
+  - Automatic .na file discovery in pytest
+  - Custom test items and reporting
+  - Dana-specific CLI options
+- **Configuration support** (`datest/config.py`)
+  - TOML configuration files
+  - Support for datest.toml and pyproject.toml
+  - Command-line override support
+- **Enhanced CLI** with new options:
+  - `--config`: Specify configuration file
+  - `--json`: Use JSON output format
+  - `--timeout`: Set execution timeout
+  - `--no-color`: Disable colored output
+- **End-to-end tests** (`tests/e2e/`)
+- **Sample configuration** (`datest.toml`)

+
+## 🔧 Key Features
+
+1. **Test Discovery**
+   - Configurable file patterns
+   - Recursive directory traversal
+   - Exclude patterns support
+
+2. **Dana Execution**
+   - Subprocess-based execution
+   - Timeout support
+   - JSON output option
+   - Proper error handling
+
+3. **Assertion Parsing**
+   - Parses Dana assertions, logs, and errors
+   - Supports both text and JSON formats
+   - Line number extraction
+   - Pass/fail detection
+
+4. **Rich Reporting**
+   - Colored console output
+   - Detailed assertion display
+   - Summary statistics
+   - Configurable verbosity
+
+5. **pytest Integration**
+   - Seamless .na file discovery
+   - Custom test items
+   - Dana-specific markers
+   - CLI option integration
+
+6. **Configuration**
+   - TOML-based configuration
+   - Hierarchical settings
+   - Command-line overrides
+   - Auto-discovery of config files
+
+## 🚀 Usage Examples
+
+```bash
+# Basic usage
+datest tests/
+
+# Discovery only
+datest --discover-only tests/
+
+# Verbose with custom pattern
+datest -v --pattern "spec_*.na" tests/
+
+# With configuration file
+datest --config myconfig.toml tests/
+
+# JSON output with timeout
+datest --json --timeout 60 tests/
+
+# pytest integration
+pytest tests/  # Will discover and run .na files
+
+# pytest with Dana options
+pytest --dana-json --dana-timeout 45 tests/
+```
+
+## 📊 Test Coverage
+
+- **Unit Tests**: Comprehensive coverage for all modules
+- **Integration Tests**: Full pipeline testing with mocked Dana
+- **End-to-End Tests**: CLI and configuration testing
+- **Test Fixtures**: Example Dana test files
+
+## 🔄 Exit Codes
+
+- `0`: All tests passed
+- `1`: Test failures detected
+- `2`: Error (Dana not available, configuration error, etc.)
+
+## 📝 Configuration Example
+
+```toml
+[discovery]
+patterns = ["test_*.na", "*_test.na"]
+exclude = [".*", "__pycache__"]
+recursive = true
+
+[execution]
+command = "dana"
+timeout = 30.0
+json_output = false
+
+[output]
+verbose = false
+color = true
+timings = true
+
+[pytest]
+enable = true
+```
+
+## 🎉 Summary
+
+The Datest MVP is now complete with all three phases implemented. The framework provides:
+
+- ✅ Dana test file discovery and execution
+- ✅ Rich assertion parsing and reporting
+- ✅ Full pytest integration
+- ✅ Flexible configuration system
+- ✅ Comprehensive test coverage
+- ✅ Production-ready error handling
+
+The implementation follows the KISS principle while providing a solid foundation for future enhancements like parallel execution, coverage analysis, and Dana-specific assertions.
