示例1: TestRegister

func TestRegister(t *testing.T) {
	graph, _ := tempGraph(t)
	defer nukeGraph(graph)
	archive, err := fakeTar()
	if err != nil {
		t.Fatal(err)
	}
	image := &image.Image{
		ID:      common.GenerateRandomID(),
		Comment: "testing",
		Created: time.Now(),
	}

	if err != nil {
		t.Fatal(err)
	}
	if images, err := graph.Map(); err != nil {
		t.Fatal(err)
	} else if l := len(images); l != 1 {
		t.Fatalf("Wrong number of images. Should be %d, not %d", 1, l)
	}
	if resultImg, err := graph.Get(image.ID); err != nil {
		t.Fatal(err)
	} else {
		if resultImg.ID != image.ID {
			t.Fatalf("Wrong image ID. Should be '%s', not '%s'", image.ID, resultImg.ID)
		}
