Golang New Examples

Example #1

File: papertrail_test.go Project: elleFlorio/gru

func TestWritingToUDP(t *testing.T) {
	port := 16661
	udp.SetAddr(fmt.Sprintf(":%d", port))

	hook, err := NewPapertrailHook("localhost", port, "test")
	if err != nil {
		t.Errorf("Unable to connect to local UDP server.")
	}

	log := logrus.New()
	log.Hooks.Add(hook)

	udp.ShouldReceive(t, "foo", func() {
		log.Info("foo")
	})
}

Example #2

File: syslog_test.go Project: elleFlorio/gru

func TestLocalhostAddAndPrint(t *testing.T) {
	log := logrus.New()
	hook, err := NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")

	if err != nil {
		t.Errorf("Unable to connect to local syslog.")
	}

	log.Hooks.Add(hook)

	for _, level := range hook.Levels() {

			t.Errorf("SyslogHook was not added. The length of log.Hooks[%v]: %v", level, len(log.Hooks[level]))
		}
	}

	log.Info("Congratulations!")
}

Example #3

File: bugsnag_test.go Project: elleFlorio/gru

	msg := make(chan string, 1)
	expectedMsg := "foo"

	ts := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
