Which command starts the test runner?

Explanation:
Tests are started by the script named test in your project's package.json. Running npm test tells npm to execute that script, which launches the test runner (often Jest) configured for the project. In typical React setups, this runs the tests in watch mode and keeps watching for changes. This is different from starting the development server, ejecting configuration, or building for production. So the command to start the test runner is npm test.
