  1. I don’t seem to have the .of method on my entity class. I see you use Playlist.of to create an object to test against. What am I missing?

  2. About the Playlist.of method yet, lets say we extend Playlist from a BaseEntity, could we implement it there? If so, how would we deal with the types? Thanks

  3. This is a great article and would have been better if there was a sample Github repository to see all the code examples at once.

  4. This is a great article to know the concept of testing, and how to do it with the nest.
    It helps me a lot to do testing.
    Thank you so much for sharing your knowledge.
