Summary

“Run/Debug Tests” Pester code lense no longer work in latest extension preview. Caused by InvokePesterStub.ps1 being called with parameters with embedded single quotes.

@fflaten I saw the same issue in my Pester Tests extension, something about the double quoting of the first arg got “fixed” whereas before it was being removed. https://github.com/pester/vscode-adapter/issues/88
