Hello man,
I think you can easily accomplish this task declaring a variable, using
file.open to read a XML from your file system, and stubbing your method
call on your test. This is the most common way of doing some tests with
third party apis. But, if you want a more reliable way to do some test with
API, I would recommended for you to try VCR. I am not a minitest guy, but I
think VCR have setup to works fine with minitest too.
Have a nice day man
