MUnit: your new favorite Scala testing library?
summary
MUnit positions itself as a fast, cross-platform Scala test framework with a tiny core and only an optional ScalaCheck module, claiming no DSL and a single recommended style. It shows smart code-frame diffs and copy‑pasteable expected values, grays out framework stack frames, supports reusable fixtures as composable values, and manages flaky tests with annotations and CI reporting. Integration uses transforms (value and test transforms) so Cats‑Effect or custom runtimes plug in with a few lines, and tests can be marked expected to fail.
