DiffEngine

So I built a thing https://github.com/VerifyTests/DiffEngine

It allows for convention based detection and launch of a number of diff tools https://github.com/VerifyTests/DiffEngine/blob/master/docs/diff-tool.md#supported-tools

I was wondering if this would be useful to expecto?

I was thinking expecto could launch and close diff tools when a test fails or succeeds?

Is this something that would interest you? If so i am happy to pair with you to work on. Unfortunately i lack the skill in f# to submit a PR on my own.

So there's an abstraction in Expecto for diffing; it gets invoked with the two bodies to diff; and with Expecto.Diff you get nice output from this.

As such, Expeco doesn't create files by itself. A plugin like you describe would have to create those files.

I'm actually not sure how wanted this would be; I've managed 6 years with a lot of tests written in Expecto without needing a tool like this, but I'm not sure others would agree. Have you done some market research about what people want?

fair enough. if you dont think it is useful, then probably not worth the effort

I may not be your target audience, but I want expecto to cater for many different audiences. If you find it useful or you have a good use case I’m open to discussion. The door to converse about this is always open. 👌
