// TestFatal is used to do tests which are supposed to be fatal
func TestFatal(t *testing.T) {
    origLogFatalf := logFatalf

    // After this test, replace the original fatal function
    defer func() { logFatalf = origLogFatalf } ()

    errors := []string{}
    logFatalf = func(format string, args ...interface{}) {
        if len(args) > 0 {
            errors = append(errors, fmt.Sprintf(format, args))
        } else {
            errors = append(errors, format)
        }
    }
    if len(errors) != 1 {
        t.Errorf("excepted one error, actual %v", len(errors))
    }
}
