Function TestSpec_PublicAPI_IsGoneError

pkg/errorutil/spec_test.go:87–109

TestSpec_PublicAPI_IsGoneError validates the documented behavior of IsGoneError as described in the errorutil README.md. Specification: - Returns true when err indicates an HTTP-style 410/"gone" response by matching case-insensitive patterns like "HTTP 410" or "410 Gone". - Returns false for nil an

(t *testing.T)

//   - Design note: requires HTTP-style status context so unrelated phrases
//     like "gone away" are not misclassified.
