Thank you! That's perfect.

Uh tests failed I'll check 🤔

[charliermarsh]

It looks like something frustrating with the filters. Maybe try running without context.filters() to see what's happening?

[blueraft]

It's an issue with path.user_display() function stripping off the temp dir path, what do you think of using path.simplified_display() function here instead? The test passes on both MacOS and Ubuntu then (haven't tested on Windows yet).

[charliermarsh]

That seems ok to me... user_display just truncates if it's relative, which is rare for these cases (and probably not desired anyway).

[charliermarsh]

Can you change cache dir as well for consistency?

[blueraft]

Done
