Run Tests only up to a specific stage(GitHub)

I’m interested in recording a demo of my interpreter project at the stage it’s at currently, because honestly, I barely passed this most recent stage with a lot of luck. Is there a way to go back and run tests for a specific stage via the GitHub pushes? I’m on windows, so I can’t use the CLI unfortunately, otherwise I know there’s a feature through that. I don’t want to advance to the next stage and show failing tests in the demo.

Are you able to install WSL? The CLI does work within WSL. With just git unfortunately no way to test previous stages.
