Platform: Ubuntu 20.04.3

Apologies for leaving out this detail

Hey @ShonFrazier, thanks for reaching out & checking out the project. I forgot a .upToNextMinor(...) in the package file. I've updated it now so it should work.

FYI development is now being done in the async branch; it's fully async/await and has been ready for a couple months but I'm waiting to merge it until test discovery is available for swift on Linux.

While the docs aren't fully up to date there, if you're interested in async/await APIs, you might consider giving that branch a try. It should be merged into main soon.

[ShonFrazier]

Thanks, @joshuawright11, for the timely reply. That change fixed my problem.

Looks like Linux test discovery came with 5.4:

Automatic test discovery is now the default on all platforms, removing the need in LinuxMain.swift (which has been deprecated)

from: https://www.swift.org/blog/swift-5-4-released/

[joshuawright11]

Ah, I meant async/await test discovery on Linux. Though it looks like 5.5.2 fixes that!

Still some crashes in expectation on Linux, but was able to refactor tests to avoid those.
