The first question I ask myself before I write a unit test is, "what do I want to test?" In this case, I'll test a method called GetDirPath in my Go pkg called image.go.
GetDirPath uses the Go core packages user and path to return a file path.

func (v *ImageClient) GetDirPath(imageName string) (string, string, error) {
home, err := |

v.GetHomeDir() |
...
dirPath := path.Join(home, "images", v.storeName) |
...
filePath := path.Join(dirPath, imageName) |
...
return filePath, dirPath, err |
...
} |
