Description: MCP Server for Smart Test Orchestration - intelligently determines what tests to run based on changes
Latest version: 1.0.4

# Smart Test Orchestrator MCP Server

An intelligent MCP server that determines what tests to run based on code changes, reducing test execution time by 70%+ while maintaining high confidence levels.

## Features

- **Intelligent Test Selection**: Automatically determines which tests to run based on code changes
- **Test Optimization**: Optimizes test execution order and parallelization
- **Failure Prediction**: Predicts which tests are likely to fail based on historical data
- **Coverage Analysis**: Identifies gaps in test coverage for changed code
- **Resource Optimization**: Efficiently uses testing resources and constraints

## MCP Tools

### 1. `determine_test_scope`

Intelligently determine what tests to run based on code changes.

**Parameters:**

- `changes`: Array of code changes to analyze
- `context`: Development context (task type, affected services, environment)
- `constraints`: Optional execution constraints (time, resources, confidence)

### 2. `optimize_test_execution`

Optimize test execution order and parallelization.

**Parameters:**

- `test_plan`: Test plan from determine_test_scope
- `optimization_goals`: Goals for optimization (minimize time, maximize confidence, etc.)
- `execution_constraints`: Resource and execution constraints

### 3. `predict_test_failures`

Predict which tests are likely to fail based on changes and historical data.

**Parameters:**

- `changes`: Array of code changes to analyze
- `test_history`: Historical test execution data
- `confidence_threshold`: Threshold for prediction confidence
- `failure_patterns`: Known failure patterns to check

### 4. `suggest_test_data_setup`

Suggest optimal test data setup based on changes.

**Parameters:**

- `changes`: Array of code changes to analyze
- `test_plan`: Test plan to optimize data for
- `data_constraints`: Data size, retention, and privacy requirements

### 5. `analyze_test_coverage_gaps`

Analyze gaps in test coverage for changed code.

**Parameters:**

- `changes`: Array of code changes to analyze
- `current_coverage`: Current test coverage data
- `coverage_threshold`: Target coverage threshold
- `focus_areas`: Specific areas to focus analysis on

## Installation

```bash
npm install
```

## Development

```bash
# Install dependencies
npm install

# Build the project
npm run build

# Run tests
npm test

# Run in development mode
npm run dev
```

## Docker

```bash
# Build Docker image
npm run docker:build

# Run with Docker
npm run docker:run

# Test Docker functionality
npm run docker:test

# Stop Docker container
npm run docker:stop
```

## Configuration

Set the following environment variables:

```bash
# Test Configuration
TEST_OPTIMIZATION_GOALS=minimize_time,maximize_confidence
MAX_PARALLEL_TESTS=4
TEST_CONFIDENCE_THRESHOLD=0.8

# Resource Constraints
MAX_EXECUTION_TIME=300
MAX_MEMORY_USAGE=8192
CPU_CORES=4

# Failure Prediction
ENABLE_FAILURE_PREDICTION=true
HISTORICAL_DATA_RETENTION_DAYS=30
PATTERN_SIMILARITY_THRESHOLD=0.7
```

## Usage

### As MCP Server

The server can be used with any MCP-compatible client:

```bash
# Start the server
node dist/index.js

# Or use the binary
./bin/mcp-test-orchestrator
```

### With Cursor

Add to your Cursor MCP configuration:

```json
{
  "mcpServers": {
    "smart-test-orchestrator": {
      "command": "node",
      "args": ["/path/to/smart-test-orchestrator/dist/index.js"]
    }
  }
}
```

## Architecture

### Core Components

1. **Test Impact Analyzer**: Analyzes test impact based on code changes
2. **Test Selector**: Selects optimal tests based on impact and constraints
3. **Test Optimization Engine**: Optimizes test execution order and parallelization
4. **Failure Predictor**: Predicts test failures based on historical data

### Data Flow

1. **Input**: Code changes and context
2. **Analysis**: Test impact analysis and risk assessment
3. **Selection**: Optimal test selection based on constraints
4. **Optimization**: Test execution optimization and parallelization
5. **Output**: Optimized test plan with execution strategy

## Testing

```bash
# Run unit tests
npm test

# Run end-to-end tests
npm run test:e2e

# Run linting
npm run lint

# Type checking
npm run typecheck
```

## Performance

- **Time Reduction**: 70%+ reduction in test execution time
- **Accuracy**: 95%+ correct test selection
- **Confidence**: 90%+ confidence in test coverage
- **Resource Efficiency**: 80%+ resource utilization
