Angular 16 Gets Experimental Jest Support

Jest is well-known for its ease of use, quickness, and extensive testing capabilities. Angular hopes to give developers with a more flexible and efficient testing experience by integrating experimental Jest support. This action is a direct response to the developer community, which has embraced Jest for its multiple benefits.

Configuring Jest in Angular 16

Follow these steps to get started with Jest in your Angular 16 projects:

Step 1: Install Jest as a dev dependency in your project using npm:

npm install jest --save-dev

Step 2: Update the angular.json file in your project's root directory. Locate the "test" section under the "architect" section and modify it as follows:

{
  "projects": {
    "my-app": {
      "architect": {
        "test": {
          "builder": "@angular-devkit/build-angular:jest",
          "options": {
            "tsConfig": "tsconfig.spec.json",
            "polyfills": ["zone.js", "zone.js/testing"]
          }
        }
      }
    }
  }
}

By making "builder": "@angular-devkit/build-angular:jest", you told Angular to use Jest as the testing framework for your project.
