Testing
This project uses Jest for testing. The tests are located in the src/__tests__ directory.
Running Tests
You can run the tests using one of the following commands:
# Run tests using the custom script (with coverage)
node run-tests.cjs
# Run tests using npm scripts
npm test # Run tests without coverage
npm run test:coverage # Run tests with coverage
npm run test:custom # Run tests with custom script (same as node run-tests.cjs)
The test coverage report will be generated in the coverage directory.
Running evals
The evals package loads an mcp client that then runs the index.ts file, so there is no need to rebuild between tests. You can load environment variables by prefixing the npx command. Full documentation can be found here.

Contributing
When adding new tools, please be mindful of the tool name length. Some clients, like Cursor, have a 60-character limit for the combined server and tool name (server_name:tool_name).
Our server name is playwright-mcp. Please ensure your tool names are short enough to not exceed this limit.
