npm:test:run

The command "npm test" is a command that is used within Node Package Manager (NPM) to run the tests of a project. It is typically used in projects that utilize automated testing frameworks, such as Mocha, Jest, or Karma.

When you run "npm test" in the command line, NPM looks for a predefined "test" script in the package.json file of your project. This script could be any command that you want to execute to run your tests.

Typically, the "test" script will run a test runner, which is responsible for executing the tests inside your project. The behavior of the test runner depends on the specific testing framework used in your project. For example, if you're using Jest, the "test" script might execute the "jest" command, which in turn runs the tests defined in your project.

By running "npm test", you can easily execute your tests and check the results in the command line. The command is often used in continuous integration pipelines or as a part of development workflows to ensure that the code changes or updates do not break existing functionality.
