Have always personally seen Gherkin being used with Cucumber, as I believe that they’re two parts of the same whole, but I’m happy to be corrected if wrong :).

My understanding is that Gherkin is the syntax used to write the scenarios / acceptance criteria, whilst Cucumber is the tool that interprets said scenarios and executes them as automated tests.

The snaps on this are giving me major flashbacks, though I can’t put my finger on anything specific. My mum was a seamstress and I’m sure I remember finding and playing with something exactly like this in her room as a kid back in the 80s. Will reply here if it comes back to me :) the fact it’s adjustable to fixed intervals via the snaps seems too purposeful and practical, though - especially with the metal presumably giving rigidity to whatever it’s used for.

I can read text in any orientation, even if mirrored, as easily as if it was right side up / not mirrored. Not sure why, and almost completely useless, but was surprised to discover that supposedly not everyone can do this?
