[Co-Hosting]: London Scala Talks: Gabriele Petronella and Jacob Wang

I talk:

Gabriele Petronella: MUnit: your new favorite Scala testing library?

MUnit is a testing library for Scala built. “Another one?!”, you may say? In this talk we’ll explore
together the most notable features of MUnit and see what makes this
little library unique!

Via a series of live code examples, we’ll answers questions like “Why
does MUnit not have a DSL?”, “How do we integrate MUnit with other
libraries?” and “How can MUnit help dealing with flaky tests?”.

At the end the presentation, MUnit may become your new favorite testing library!

Jacob Wang: Time-warping in tests with Cats Effect

How do you test time‑sensitive application logic? In this talk, we will explore what lives under `ExecutionContext` and `cats.effect.Timer` and how these abstractions allow us “warp” forward in time. Armed with our new knowledge, we will then look at how time‑sensitive tests are structured to make them fast and reliable.

This talk uses cats-effect in its examples but a lot of the concepts are shared across all effect libraries in Scala, so if you use ZIO or even just plain Scala Futures, you too can learn the secrets behind time-warping and perform the magic yourself :)
