Yes, that's correct. I followed README and ran all below steps to create virtualenv. Attached is the output of all commands I ran successfully except the last one i.e. pytest.
Could you please let me know if you see anything wrong or missing?

See: > File "/usr/local/lib/python2.7/dist-packages/_pytest/assertion/ > rewrite.py", line 213, in load_module Are you using virtualenv to create a python 3 environment to use with the tests? From README.md: **Note**: While virtualenv isn't strictly required, using virtualenv is almost always the quickest path to success as it provides common base setup across various configurations. 1. Install virtualenv: ``pip install virtualenv`` 2. Create a new virtualenv: ``virtualenv --python=python3 --no-site-packages ~/dtest`` 3. Switch/Activate the new virtualenv: ``source ~/dtest/bin/activate`` 4. Install remaining DTest Python dependencies: ``pip install -r /path/to/cassandra-dtest/requirements.txt`` Regards, Ariel On Mon, Mar 26, 2018, at 11:13 AM, Tyagi, Preetika wrote: > I was able to run requirements.txt with success.
