Integration Tests - These tests will call directly into your code. For example, you can use an integration test to call an Angular service. Typically each test will focus on one function. The test calls the target function with a set of parameters and then checks to make sure the results match expected values. Each individual test now only contains the code specific to that test, and not code that is general across all tests. As you expand your tests, keep an eye out for locations where you can use beforeEach to tidy up tests. beforeEach isn't the only function of this sort that Jasmine provides, and the documentation lists the others. Testing Filters. How to use jasmine and karma to write unit tests for your AngularJS apps not just within Visual Studio, but any IDE.
To run our tests, we run the following command in our Angular CLI project: ng run e2e. This will trigger Protractor to open the browser to start our app and run our tests.
