TableView cells act as our primary mode of presentation in our application. In this video, learn how to mock a cell, and write tests to make sure that it dequeues from the TableView properly.
We're going to move on to testing our TableView cell right now,…which is normally a no-brainer, right?…We create a cell, we hook it up,…and we configure it with our data.…But because we're starting…to test out the TableView functionality,…we're going to introduce the concept of mocks.…Now, in essence, mocks are exactly what they sound like:…a mock-up or stand-in for the real thing in our app.…We're going to be using mocks pretty heavily from now on,…so it's a good time to get really familiar with the topic.…So while we're still in our library data service tests,…let's add a new pragma mark,…and we're going to call this Cells, and let's start off…with a new func testCell_RowAtIndex_ReturnsMovieCell.…
Now, inside this test,…we're just going to call sut.movieManager.addMovie.…We're going to add in darkComedy,…and we're going to reload our table view,…so libraryTableView.reload, and finally,…we need to pull out the new dequeued cellForRow,…so let cellQueried = libraryTableView.cellForRow,…and it's looking for an index path,…
