Manual Setup

This guide covers setting up di-test without the Claude Code plugin system. If you’re using the plugin, dependencies are installed automatically — you don’t need this.

Prerequisites

• Python 3.10+
• Node.js v18+
• CWAC installed at a discoverable location (optional — fallback mode works without it)

Steps

1. Clone the repository:

   git clone https://github.com/cgbarlow/di-test.git
   cd di-test
   

2. Install Python dependencies:

   pip install -r cwac_mcp/requirements.txt
   

3. Install Node.js dependencies (Playwright + axe-core):

   npm install
   

4. Install the Playwright Chromium browser:

   npx playwright install --with-deps chromium
   

5. (Optional) Install CWAC for full mode:

   git clone https://github.com/GOVTNZ/cwac.git ../cwac
   cd ../cwac && pip install -r requirements.txt && npm install && cd -
   

   Or set CWAC_PATH to an existing CWAC installation. Without CWAC, the scanner runs in axe-core only fallback mode.

6. Both MCP servers are configured in .mcp.json. Claude Code will discover them automatically.

Running Tests

pytest tests/

The test suite includes 103 pytest tests across 9 test files covering environment detection, axe-core scanner, config builder, result reader, scan registry, report generation, templates, and plugin manifest.

Verifying the Environment

You can check which scanning mode is available:

from cwac_mcp.environment_check import check_environment
result = check_environment()
print(result["mode"])     # "cwac" or "axe-only"
print(result["message"])  # Human-readable summary
