> Is it possible to test this? > Not really, my impression is this wouldn’t be easy to test anyway, hence the question 😛 Yes. We often do a mock-only tests and It's also important. Mock is really a representation of "How the author imagined the code would interact with the external world". Since you tested it, and you have good understanding how it works. Coding that in the form of mock is capturing that knowledge. Imagine somene else making a change to that code 2 months from now. Or even YOURSELF doing the 2 months from now (I always try to picture future-self coming back to the code after I completely forgot what it does). If there is no mock and someone changes the behaviour accidentally, they won't notice and it might stop working accidentally. But when it fails, you will look at your test, and you will be able to quickly recall the intent you had without heavy debugging. I really treat those tests with mocks often as description of what I thought the class in question shoudl be doing - so that I even don't have to remember it. -- This is an automated message from the Apache Git Service.
