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.

We won't implement 100% of the tests for the project so we don't have to mock all the methods. Please feel free at the end of the chapter to implement tests for all the methods as an exercise.

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...
