In this weekly livestream series, I pair up with Ted M. Young, aka jitterted, to look at Nullables and A-Frame Architecture as an alternative to Mocks, Spies, and Hexagonal Architecture. Each episode combines a healthy dose of architecture and design discussion with hands-on coding.

Watch us live every Monday! For details, see the event page. For more episode recordings, see the episode archive.

In this episode...

In the last few episodes, we made the adapters for Ted’s scoring service Nullable. These are the “out” or “secondary” adapters in the codebase’s Hexagonal architecture.

Now that the adapters are Nullable, we see an opportunity create a low-level HttpClient adapter that the scoring service adapters can use. This should simplify the Nullability logic in those adapters and open up new opportunities for testing. We start with the get() method and the Nullable’s configurable responses.
