Hi @scolladon,

Apologies for the delayed reply...I was on vacation all of last week. I just did the following to verify your fix:

1. Followed your instructions to install the plugin from this PR branch
2. Re-ran the command I posted in Jest tests copied to output folder when using --generate-delta #744 against my fork of the sfdx-git-delta-reproduction-playground
3. Verified that the __tests__ folder and its contents are no longer copied to the plugin output folder

Thanks!
