const (

	// EUFrequencyPlanID is a European frequency plan for testing.

Variables

View Source 
var DefaultContext = context.Background()

DefaultContext is the default context.

var Delay = time.Millisecond * func() time.Duration {
	env := os.Getenv("TEST_SLOWDOWN")
	if env == "" {
		return 1
	}

	v, err := strconv.Atoi(env)
	if err != nil {
		return 1
	}
	return time.Duration(v)
}()

Delay is the value, which can be used to slowdown the execution of time-dependent tests. You can assume, that most function calls will return in at most Delay time. It can(and should) be used to construct other time variables used in testing. Value may vary from machine to machine and can be overridden by TEST_SLOWDOWN environment variable.
