Mocking the API
There are different ways to test our application. Testing the API is beyond the scope of this book, but we still need to test the components, which are dependent on the API. We could spin up the API and test against the API, but in this case, we are only interested in testing the Blazor component.
We can then mock the API or create a fake copy of the API that doesn’t read from the database but reads from a predefined dataset. This way, we always know what the output should be.
Luckily, the interface we created for our API is just what we need to create a mock API.
We won’t implement 100% of the tests for the project, so we don’t have to mock all the methods. Please feel free to implement tests for all methods as an exercise at the end of the chapter.
There are two ways we can implement the mock API. We could spin up an in-memory database, but to keep things simple, we will choose the other option and generate posts when we ask for...
