Howto disable unit test runs, when building custom Python packages

[Timothy Washington]

I'm trying to figure out "Howto disable unit test runs, when building
custom Python packages".
I am trying to create a custom guix package of maurosoria/dirsearch
<https://github.com/maurosoria/dirsearch>.
Using this config
<https://github.com/twashing/dotfiles/blob/main/guix/packages/dirsearch.scm>,
"guix build" seems to work, except that it runs the project's unit tests.
But iIt fails when running the project's unit tests, with these logs
<https://snippet.host/fzavuc>.

Details are in this SO post
<https://stackoverflow.com/questions/76595986/howto-disable-unit-test-runs-when-building-custom-python-packages>
.
But basically, when building a custom (Github hosted) Python package, how
can we disable unit test runs?

Thanks
Tim
