[Bug]: URLSearchParams#get(k, v) is not implemented and uses URLSearchParams#get(k) instead

[kvndrsslr]

Version

29.7.0

Steps to reproduce

Prepare

git clone https://github.com/kvndrsslr/jest-bug-urlsearchparams-has-k-v.git
cd jest-bug-urlsearchparams-has-k-v
npm ci

Test

npm run test

This fails only on ./jsdom-test-env.test.js.
Now try to comment out line 3 in ./jest.config.js and run again:

npm run test

This time all the tests pass.

Expected behavior

URLSearchParams.has(k,v) works as expected.

Actual behavior

Instead of URLSearchParams.has(k,v), only URLSearchParams.has(k) is implemented and hence returns false positives in tests that contain .has(k,v)

Additional context

URLSearchParams#has(k,v) seems to be not correctly implemented in jest only when using testEnvironment: 'jsdom'.
I have no idea where this goes wrong, as it works in node by default and it works when testing jsdom and whatwg-url in isolation too.

Environment

System:
    OS: macOS 14.4
    CPU: (12) arm64 Apple M2 Pro
  Binaries:
    Node: 18.19.1 - ~/.volta/tools/image/node/18.19.1/bin/node
    npm: 10.2.4 - ~/.volta/tools/image/node/18.19.1/bin/npm
    pnpm: 8.15.0 - ~/.volta/bin/pnpm
    bun: 1.0.30 - /opt/homebrew/bin/bun
  npmPackages:
    jest: ^29.7.0 => 29.7.0

That's because you're using jsdom@24 in your test, which is the newest version. If you install jsdom@20 (which is what ships with Jest) you can see the test failing in the same way with the builtin test runner.

jest-environment-jsdom@next (v30 alpha) ships with jsdom@22. You can setup a version with jsdom@24 using https://www.npmjs.com/package/@jest/environment-jsdom-abstract
