 In order to run tests in a virtual environment for cqlshlib, run cassandra-cqlsh-tests.sh in this directory. It will
 automatically setup a virtualenv with the appropriate version of Python and run tests inside it.

-There are Dockerfiles that can be used to test whether cqlsh works with a default, barebones
-Python installation. Assuming Cassandra's source is checked out at `$CASSANDRA_DIR`. To test, first
-build the Docker image containing the barebones Python installation -

-Next, run cqlsh inside the newly built image -

-If `host.docker.internal` isn't supported, then you can use `--net="host"` with `docker run`:
