Functions

func Ensure

func Ensure(t TestingT, file, params string)

Ensure ensures that parameterized test parameters in a test metadata are up-to-date.

file is a file name of a .go file containing a Tast test definition (i.e. testing.AddTest call). params is a Go literal expression as a string that represents test parameters.

If TAST_GENERATE_UPDATE environment variable is not set, this function checks if parameterized test parameters in file matches with params. If any mismatch is found, it reports a test error with a message prompting users to regenerate parameterized test parameters.

If TAST_GENERATE_UPDATE environment variable is set, this function rewrites the testing.Test literal in file with params.

func Template

func Template(t TestingT, text string, data interface{}) string

Template is a utility function to render a Go template into a string in a single call.

Go's standard template engine is used to render a template string. See https://godoc.org/text/template for the template syntax.

This function also installs a few helper function that can be called inside templates:

fmt(v interface{}) string - Formats v in a Go syntax. Supported types are
  boolean, integer, float, string, slice of supported types, map of
  supported types.

Types

type TestingT

type TestingT interface {
	Helper()
	Logf(format string, args ...interface{})
	Errorf(format string, args ...interface{})
	Fatalf(format string, args ...interface{})
}

TestingT is a subset of testing.T. Exported functions in this package take TestingT instead of testing.T to allow unit-testing.
