> Since we use Python unit tests to test Cosmopolitan Libc.

Does anyone how this is meant?

They leverage Python's unit tests, running them on a cosmopolitan-libc linked Python version?

Author here. We have 364 separate test programs in the Cosmopolitan repository. However most of our testing comes from running the tests of huge existing projects that use libc, e.g. Python. Try running this on Linux:

    git clone https://github.com/jart/cosmopolitan.git
    cd cosmopolitan
    make -j16 o//third_party/python
That command will build Python and all its dependencies from scratch within the hermetic monorepo in addition to running its unit tests. On my $1,000 Core i9-9900 PC this takes 31.078 seconds.
