Jasmine in Action

Running Jasmine test

The first thing we need to do is have an example piece of code to test.

Say we have a function that returns the name of the book in the browser. This function would look like this:

function writeTitle() {
   return 'Getting Started With Angular';
}

A very simple function, but it will allow us to write a simple test. The test will look like this:

describe('writeTitle function', () => {
       it('returns Getting Started With Angular', () => {
           expect(writeTitle()).toEqual(
               'Getting Started With Angular'
           );
       });
});

So, this is our first test. It is a very simple example, but it does have a lot going on. There are a number of features of the Jasmine framework being used in this example. Let’s take a minute to explore what these features are.
