Setting Up and Tearing Down Jasmine Tests
Explore how to set up and tear down Jasmine tests using beforeEach, afterEach, beforeAll, and afterAll functions. Understand the structure of test suites with describe and it blocks, and learn to use fit and xit for focused testing. This lesson helps you write cleaner, more maintainable unit tests in Angular applications.
The beforeEach and afterEach functions
In the example below, we have two tests. In each case, we create a book object and then call a function on it. On line 1, the getShortSummary function uses string interpolation to combine the title and year values. On line 6, the getLongSummary function uses string interpolation to combine the title, author, and year values.
We use the beforeEach function on line 14. The beforeEach function takes an anonymous function as its argument and runs it before each test. In the example, we use the beforeEach function to reset the value of the book object. This makes our test code cleaner and also protects us from accidentally changing the value of the book ...
