Consider adding "testing/expect.ts" module

See original GitHub issue

Jest is arguably the most popular testing framework for Node ecosystem at the moment. It uses expect style assertions, which seems to be very popular way of exercising tests too.

I was prompted to consider it by a recent issue in vitest (which seems to be somewhat compatible with Jest.

To be clear: I prefer to write tests using testing/asserts.ts, but we shouldn’t limit ourselves to only a single style, if the other is also very popular (> 8mm weekly downloads) then we should consider adding it too.

I am currently redesigning the internal interface of expect. The type definition complexity of unitest’s expect was not good, so I am designing it to be as simple as possible.

Hopefully, I may be able to submit a Draft PR in the near future.

You can check this work in progress. https://github.com/TomokiMiyauci/expect.js

@kt3k Thanks for the response.

I will start working on the pull request. It may possibly be different from the current unitest implementation.
