Writing abstractions in tests can be surprisingly similar to storytelling. The most masterful stories are those where the author has stripped away all of the extra information, and given you just enough knowledge to be immersed and aware of what is going on. But striking that balance can be tricky, both in storytelling and abstractions in tests. Too much information and you risk overwhelming the reader. Too little and they won’t understand why things are operating the way they are. Today, Stephanie and Joël get into some of the more controversial practices around testing, why people use them, and how to strike the right balance with your information. They discuss the most common motivations for introducing abstractions, from improved readability to simplifying the test’s purpose and the types of tests where they are most likely to introduce abstractions. Our hosts also reflect on how they feel about different abstractions in tests – like custom matchers and shared examples – outlining when they reach for them

Explore how riffing enhances collaboration, improves communication with and between teams, identifies alternative code, why “clever code” does not make for good solutions, and much more! Tu

The term ‘nil’ refers to the absence of value, but we often imbue it with much more meaning than just that. Today, hosts Joël and Stephanie discuss the various ways we tend to project extra semantics onto nil and the implications of this before unpacking potential alternatives and trade-offs. Joël and Stephanie highlight some of the key ways programmers project additional meaning onto nil (and why), like when it’s used to create a guest session, and how this can lead to bugs, confusion, and poor user experiences. They discuss solutions to this problem, like introducing objects for improved readability, before taking a closer look at the implications of excessive guard clauses in code. Our hosts also explore the three-state Boolean problem, illustrating the pitfalls of using nullable Booleans, and why you should use default values in your database. Joël then shares insights from the Elm community and how it encourages rigorous checks and structured data modeling to manage nil values effectively.
