Majestic

About Majestic

Majestic is a graphical user interface for Jest, the JavaScript testing framework. It allows users to run all tests or a single file, toggle watch mode, update snapshots, examine test failures as they happen, and view console.log output within the UI for debugging. It includes a built-in coverage report and a test search feature, and supports Flow and TypeScript projects as well as projects created with Create React App.

The tool works with Jest version 20 and above and can be run via npx, or installed globally through Yarn or Npm. It can also be launched as a Chrome app using the --app flag. Configuration is done through a majestic key in package.json, supporting options such as a custom Jest script path, additional arguments, environment variables, and setups for projects with multiple Jest configuration files. It also provides command-line arguments (--config, --debug, --noOpen, --port, --version) and keyboard shortcuts for running tests, watching, and searching.

Majestic is intended for developers using Jest who want a visual interface for running and monitoring tests rather than relying solely on the command line.
