Integration with cypress

[mammadataei]

Hi, Does anyone have a solution to integrate jest-dom with cypress? or any alternative? I need some of the assertions like toHaveAccessibleDescription, toHaveAccessibleName and toHaveErrorMessage which are not available in cypress or chai-dom.

I'd love to have something like that.

It'd be great if we could export lower level functions that implement the logic of the checks that each assertion does. Then another library (perhaps a @testing-library/cypress-dom` library) could then implement Cypress-centric chai-like assertions while re-using the same implementation.

Good. just one more thing to ask. Does the project's setup or toolchain matter? Or Are there any conventions I have to follow?

Thanks, @eps1lon for that reply. Indeed, that's a very good approach.

It'd be good if you base your initial repo structure off of copying the way jest-dom is set up. In particular, the way the package json scripts section works, which is mostly based on kcd-scripts, and how it does versioning. This will allow the automated semantic versioning to work, and make it easier to automate releases on PR merges.

Okay, I'll try to set up the structure and the scripts as is in jest-dom, but do you mind if I use typescript, vitest, and probably pnpm (for better developer experience)?

[gnapse]

About TypeScript, definitely.

About vitest and pnpm, I have never used them, so I may be negatively biased here, but I would not want this package to divert too much from the developer experience in all the other packages in testing-library. It is my understanding that we mostly use jest and npm. But feel free to make your case here if you feel strongly about it. Or let's see what others think.

Hey again, It's been quite a while 😁, and eventually, I got some time and wrote a couple of assertions. Here's the repo. There ain't much but I think it's enough for an alpha release to test if the API integrates properly with jest-dom. At the same time, I can continue adding more assertions and start cypress-dom as well.
