The 9 Go test assertions I use (and why) – Alex Edwards

A Go developer shares their preferred set of 9 custom test assertion functions as an alternative to third-party packages like testify/assert. The functions cover basic checks like Equal, NotEqual, True, False, Nil, NotNil, ErrorIs, ErrorAs, and MatchesRegexp. The author argues these minimal helpers provide better developer experience while avoiding the complexity and potential downsides of larger assertion libraries, though acknowledges trade-offs in failure message quality.
