Overview

Package testutil provides many test helpers/assertions used to simplify common testing patterns.

Functions

func DiffErr

func DiffErr(op string, resp interface{}, compare interface{}, t *testing.T, opts ...cmp.Option)

DiffErr compares 2 messages (including optional transforms) and throws a testing Fatal on diff. This assumes they are usually proto messages so will automatically include protocmp.Transform() for the caller. It's harmless for the non-proto case. Reduces 3 lines to 1 for common error checking.

func FatalOnErr

func FatalOnErr(op string, e error, t *testing.T)

FatalOnErr is a testing helper function to test and abort on an error. Reduces 3 lines to 1 for common error checking.

func FatalOnNoErr

func FatalOnNoErr(op string, e error, t *testing.T)

FatalOnNoErr is a testing helper function to test and abort when we get no error. Reduces 3 lines to 1 for common error checking.

func ResolvePath

func ResolvePath(t *testing.T, path string) string

ResolvePath takes a binary name and attempts to resolve it for testing or fatal out.

func WantErr

func WantErr(op string, err error, want bool, t *testing.T)

WantErr is a testing helper for comparing boolean expected error state. Reduces 3 lines to 1 for common error checking.
