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.

Have reviewed 16 year old code for a very well known company in the last week with this exact comment peppered throughout, alongside delightfully helpful comments like:

// do not delete or change this it just works

// TODO temporary fix added 12/09/11 to fix incident must be removed ASAP

// CAUTION this returns false here instead of true like it normally does, not sure why

// if true then matched to valid account not is true
