expect package outdated (1.13.0 --> 22.0.3)

In a PR for scrape-it, I'd like to use expect(somehowBuildPromise()).resolves.toEqual(...) in a test. However, .resolves is only available in expect 20.0.0+. (Note that the NPM expect package has been merged with and is now part of Facebook's Jest multitude of packages, see jestjs/jest#1679.)

I have tried simply updating expect, but the new version already breaks tester's test because toBeA is not existent (anymore?) in Jest's expect. So upgrading expect would require bumping tester's major version number.

Interesting! Except the toBeA are the other things working? I see the expect npm package has no content anymore...

Yeah, its NPM site confused me as well! You can find its code here: https://github.com/facebook/jest/tree/master/packages/expect.

For example, toEqual works fine for me in a clean directory with npm install expect, its code is here: https://github.com/facebook/jest/blob/0ce82e6365feb1012a1dd1a6ae230a8012d90679/packages/expect/src/matchers.js#L416
I also saw in the meantime that toBeA is a won't fix: jestjs/jest#2990
