Speaker detail

Now that we have our speakers listing nicely, it would be nice to be able to view a bit more information about a specific speaker. Let's look at the tests involved in retrieving and viewing a speakers-detailed information.

Adding to the mock API Service

In the mock API, we need to add a call to get the details for a specific speaker. We can assume that the speaker has an ID field that we can use to gather that information. As usual, let's start our tests with a simple exists check. We will need to add a new describe inside the After Initialization describe for getting a speaker by ID.

describe('Get Speaker By Id', () => {
   it('exists', () => {
     // assert
     expect(service.getById).to.exist;
   });
 });

To make this test pass, we need to add a method to the mock API.

getById() {
 }

Now, we can write a test to verify the functionality we expect when a matching speaker cannot be found. The functionality we want in this case is for a SPEAKER_NOT_FOUND message to be shown...
