Getting issues with unit tests on Windows while running the script; any help would be appreciated. I will look into it.

Hey @Peefy, @zong-zhe,
I'm getting stuck on this error when running unit tests on Windows, specifically when executing the script. Is there any way to reproduce and fix this issue locally(in macOS)?
Thanks!

Is WithCheckers more appropriate ?

[NishantBansal2003]

Since the intent was to add checkers to DepChecker one by one, I named it WithChecker to emphasise that it includes a single checker at each step. Let me know if you think another name would be more suitable!

Try adding a WithCheckers method, one array at a time.
