How to configure diff tool to not use Vim?

[tony-snoop]

Hi there,

Earlier versions of Verify.Xunit" (e.g. Version "17.8.1") would use a different diff tool (I think it was KDiff).
When upgrading to the latest package - It's now using Vim! :-(

How do I configure the diff tool to revert back to what it was using earlier and not Vim?

KDiff3 should resolve before Vim https://github.com/VerifyTests/DiffEngine/blob/main/docs/diff-tool.order.md

but i cant tell why it is resolving incorrectly on your machine. you will need to debug into it

Ah-ha! Setting the DiffEngine_ToolOrder environment variable to VisualStudio,KDiff3 has done the trick. Thank you @SimonCropp - much appreciated!

still weird that vim was resolving first
