@marlonjames To extend my [previous comment](https://github.com/cocotb/cocotb/pull/5090#issuecomment-3454038831) about [pytest-xdist](https://github.com/pytest-dev/pytest-xdist), at current moment it can only schedule test functions with [cocotb runners](https://docs.cocotb.org/en/stable/runner.html#building-hdl-and-running-tests).
