If you are interested in using python for unit testing there is also Cocotb which is a python based library for running verilog and vhdl simulations. It interfaces to the simulator and allows you to stimulate your design directly from python:

Very interesting. Will definitely look into this.

All of our tests right now are implemented as VHDL/Verilog testbenches. We automate building and running in ISim with a simple Python tool which generates xunit output. It works but its slow and kind of painful to manage testcases.
