pip install -e .

# Install Playwright browsers
playwright install

Linux/macOS

# Clone and setup
git clone https://github.com/your-repo/test-automator.git
cd test-automator

# Create virtual environment
python3.11 -m venv .venv
source .venv/bin/activate

# Install dependencies
pip install -e .

# Install Playwright browsers
playwright install

⚙️ Configuration

1. Get Google API Key

1. Visit Google AI Studio

2. Create a new API key

3. Set environment variable:

# Windows
   set GOOGLE_API_KEY=your_api_key_here
   
   # Linux/macOS/WSL
   export GOOGLE_API_KEY=your_api_key_here

2. Configure Claude Code

Option A: CLI Configuration

claude mcp add test-automator "/path/to/test-automator/.venv/bin/test-automator" -e "GOOGLE_API_KEY=your_api_key"

Option B: Manual Configuration

Add to your Claude Code configuration (`~/.claude.json`):

{
  "projects": {
    "/your/project/path": {
      "mcpServers": {
        "test-automator": {
          "type": "stdio",
          "command": "/path/to/test-automator/.venv/bin/test-automator",
          "env": {
            "GOOGLE_API_KEY": "your_api_key_here"
          }
        }
      }
    }
  }
}

Windows Path Examples

• Windows: `C:/path/to/test-automator/.venv/Scripts/test-automator.exe`
• WSL: `/home/username/test-automator/.venv/bin/test-automator`

🚀 Usage

MCP Tools Available

`generate_tests(code_path, test_type="all")`

Generate intelligent tests for your codebase:

# Generate all test types
generate_tests("/path/to/your/code", "all")

# Generate specific test type
generate_tests("/path/to/your/api.py", "unit")
generate_tests("/path/to/your/project", "integration")
generate_tests("/path/to/your/webapp", "e2e")
generate_tests("/path/to/your/api", "api")

`run_tests(test_type="all", target_path="tests/")`

Execute generated tests:

# Run all tests
run_tests("all", "/path/to/tests")

# Run specific test type
run_tests("unit", "/path/to/tests")

`analyze_test_report(report_path)`

Get LLM-powered insights from test results:

analyze_test_report("/path/to/test_results.xml")

Example Workflow

# 1. Generate comprehensive tests
generate_tests("/home/user/my-project", "all")

# 2. Run the tests
run_tests("all", "/home/user/my-project/tests")

# 3. Analyze results
analyze_test_report("/home/user/my-project/tests/results/unit_results.xml")

🔧 Troubleshooting

Common Issues

"GOOGLE_API_KEY not found"

# Set the environment variable
export GOOGLE_API_KEY="your_api_key_here"

# Or add to shell profile
echo 'export GOOGLE_API_KEY="your_api_key"' >> ~/.bashrc

"Playwright browsers not found"

# Install browsers
playwright install

# Install system dependencies (Linux)
playwright install-deps

Windows Permission Issues

# Ensure script execution is enabled
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

# Check virtual environment activation
.venv\\Scripts\\activate

WSL Display Issues (for E2E tests)

# Install X11 server for Windows
# Add to ~/.bashrc:
export DISPLAY=:0.0
