specta

Documentation - GitHub

A Go testing library that emphasizes composition and reuse through matchers and test data factories.

Build reusable, composable test components instead of duplicating assertions. Matchers compose, factories generate test data, and error messages show exactly what failed.

// Define once
var IsActiveAdmin = specta.AllOf(
    UserMatches().Active(specta.IsTrue()).Matcher(),
    UserMatches().Role(specta.Equal("admin")).Matcher(),
)

// Reuse everywhere
specta.AssertThat(t, user, IsActiveAdmin)
specta.AssertThat(t, anotherUser, IsActiveAdmin)
