Hello! Has this issue been closed? I am working on a package that uses ReTestItems, and I am able to run unit tests in VsCode. Please let me know of the progress that has been made.

I am inquiring in relation to this issue: #53. Interactive debugging is extremely useful for end-to-end tests. I would like to work on this issue, but it would be good to understand on what the integration with VsCode is as of right now.
