Package description

What is jest-cli?

The jest-cli npm package is the command line interface for Jest, a popular JavaScript testing framework. It allows developers to run tests, configure Jest options, and interact with Jest directly from the command line. Jest is widely used for testing React applications, but it can also be used for testing other JavaScript code.

What are jest-cli's main functionalities?

Running Tests

Run all tests in a project. This is the most basic and commonly used command to start the Jest test runner.

jest

Running Tests in Watch Mode

Run Jest in watch mode. This command will re-run tests when files change, which is useful during development.

jest --watch

Running Specific Tests

Run tests in a specific file or files matching a pattern. This allows for more targeted testing.

jest testFileName

Configuring Jest

Specify a configuration file for Jest. This allows developers to customize how Jest behaves, including setting up test environments, mock implementations, and more.

jest --config=jest.config.js

Coverage Reporting

Generate a test coverage report. This helps developers understand which parts of their codebase are covered by tests.
