Functions

func AssertGolden

func AssertGolden(t testing.TB, path string, update bool, got interface{})

AssertGolden compares what's got and what's in the golden file. It updates the golden file on-demand. It does nothing when the runtime is "windows".

func Exec

func Exec(helper string, envs ...string) (string, error)

Exec executes "go test" on given helper with supplied environment variables. It is useful to mock "os/exec" functions in tests. When succeeded, it returns the result produced by the test helper. The test helper should:

1. Use WantHelperProcess function to determine if it is being called in helper mode.
2. Call fmt.Fprintln(os.Stdout, ...) to print results for the main test to collect.

func Update

func Update(name string) bool

Update returns true if update regex matches given test name.

func WantHelperProcess

func WantHelperProcess() bool

WantHelperProcess returns true if current process is in helper mode.
