# Testing

# Unit test

# Installation

Ts.ED support officially two unit test frameworks: Jest and Mocha. It's also possible to use your preferred frameworks. Your feedback are welcome

    # Usage

    Since Platform Api is available, Ts.ED provides two way to test your code. If you use , look on the Legacy tab. If you use Platform API, look on v5.56.0+ tab.

      # Async / Await

      Testing asynchronous method is also possible using Promises (async/await):

        # Mock dependencies

        PlatformTest API provides an invoke method to create a new instance of your component with mocked dependencies.


          PlatformTest.invoke() executes automatically the $onInit hook!

          # Test your Rest API

          # Installation

          To test your API, I recommend you to use the supertest module.

          To install supertest just run these commands:

            # Example


              If you use the PlatformTest, you'll probably get an error when you'll run the unit test:

              Platform type is not specified. Have you added at least `import @tsed/platform-express` (or equivalent) on your Server.ts ?

              To solve it, just add the import @tsed/platform-express on your Server.ts. PlatformTest need this import to know on which Platform your server must be executed for integration test.
