Original Pull Request: https://github.com/microsoft/terminal/pull/4382

State: closed
Merged: Yes

Summary of the Pull Request

#4354 is a pretty complicated PR. It's got a bunch of conpty changes, but what it also has was some critical improvements to the roundtrip test suite. I'm working on some other bugfixes in the same area currently, and need these tests enhancements in those branches now. The rest of #4354 is complex enough that I don't trust it will get merged soon (if ever). However, these fixes should be in regardless.

PR Checklist

  • Taken directly from #4354
  • I work here
  • Tests added/passed
  • [n/a] Requires documentation to be updated

Detailed Description of the Pull Request / Additional comments

This is four main changes:

  • Enable conpty to be fully enabled in unittests. Just setting up a VT renderer isn't enough to trick the host into being in conpty mode - it also needs to have some other flags set.
  • Some minor changes to CommonState to better configure the common test state for conpty
  • Move some of the verify helpers from ConptyRoundtripTests into their own helper class, to be shared in multiple tests
  • Add a TerminalBufferTests class, for testing the Terminal buffer directly (without conpty).

This change is really easier than

would suggest, I promise.
