You indicated pty=True, but your platform doesn't support the 'pty' module!

invocations requires pty.

Ahh, yea. Forget why exactly, IIRC the spec lib doesn't print as nicely without a pty (or didn't at some point).

Some of my other libs run on Windows CI like appveyor and use the same test runner, so it should be solvable. At the very least we can put in an override parameter to the test task.
