You may want to add parameters like vcl_dir if like me you split your
VCL in multiple files. I usually put at least the backend(s)/director(s)
in a separate file, so that I can include the actual policy in test cases,
or share the same policy for different environments (QA, preprod)
without duplicating code (avoids divergence).

But if you want to test your cache policy (namely your VCL) you can do
so by mocking the backends and clients behaviors. Et voilà, you can run
your varnishtest suite in parallel :-)
