Original Pull Request: https://github.com/microsoft/terminal/pull/4429

State: closed
Merged: No

Summary of the Pull Request

When the user tries to duplicateTab with a profile that doesn't exist anymore (like might happen after a settings reload), don't crash.

PR Checklist

  • Closes Install without Windows Store (#2455)
  • I work here
  • Tests added/passed
  • [n/a] Requires documentation to be updated
  • Should we display an error dialog when this situation happens?
    • Should this be a follow-up task?

Detailed Description of the Pull Request / Additional comments

CascadiaSettings::BuildSettings can throw if the GUID doesn't exist. This wraps those calls up with a try/catch.

It also adds a couple tests - a few SettingsTests for try/catching this state. It also adds a XAML-y test in TabTests that creates a TerminalPage and then performs som UI-like actions on it. This test required a minor change to how we generate the new tab dropdown - in the tests, Application::Current() is not a TerminalApp::App, so it doesn't have a Logic() to query. So wrap that in a try/catch as well.

Validation Steps Performed

  • Ran tests - new tests pass!
  • Validated scenario manually
