This is a complete rework of our testing infrastructure. The main goal is to modernize and drop deprecated or undermaintained dependencies (specifically, grunt, karma, and testswarm). We've achieved that by limiting our dependency list to ones that are unlikely to drop support any time soon. The new dependency list includes:
- `qunit` (our trusty unit testing library)
- `selenium-webdriver` (for spinning up local browsers)
- `express` (for starting a test server and adding middleware)
- express middleware includes uses of `body-parser` and `raw-body`
- `yargs` (for constructing a CLI with pretty help text)
- BrowserStack (for running each of our QUnit modules separately in all of our supported browsers)
- `browserstack-local` (for opening a local tunnel. This is the same package still currently used in the new Browserstack SDK)
- We are not using any other BrowserStack library. The newest BrowserStack SDK does not fit our needs (and isn't open source). Existing libraries, such as `node-browserstack` or `browserstack-runner`, either do not quite fit our needs, are under-maintained and out-of-date, or are not robust enough to meet all of our requirements. We instead call the [BrowserStack REST API](https://github.com/browserstack/api) directly.
**BrowserStack**
- automatically retries individual modules in case of test failure(s)
- automatically attempts to re-establish broken tunnels
- automatically refreshes the page in case a test run has stalled
- Browser workers are reused when running isolated modules in the same browser
- runs all browsers concurrently and uses as many sessions as are available under the BrowserStack plan. It will wait for available sessions if there are none.
- supports filtering the available list of browsers by browser name, browser version, device, OS, and OS version (see `npm run test:unit -- --list-browsers` for more info). It will retrieve the latest matching browser available if any of those parameters are not specified. Supports latest and latest-\d+ in place of browser version.
- cleans up after itself (closes the local tunnel, stops the test server, etc.)
- Requires `BROWSERSTACK_USERNAME` and `BROWSERSTACK_ACCESS_KEY` environment variables.
**Selenium**
- supports running any local browser as long as the driver is installed, including support for headless mode in Chrome, FF, and Edge
- supports running `basic` tests on the latest [jsdom](https://github.com/jsdom/jsdom#readme), which can be seen in action in this PR (see `test:browserless`)
- Node tests will run as before in PRs and all non-dependabot branches, but now includes tests on real Safari in a GH actions macos image instead of playwright-webkit.
- can run multiple browsers and multiple modules concurrently
Other notes:
- Stale dependencies have been removed and all remaining dependencies have been upgraded with a few exceptions:
- `sinon`: stopped supporting IE in version 10. But, `sinon` has been updated to 9.x.
- `husky`: latest does not support Node 10 and runs on `npm install`. Needed for now until git builds are migrated to GitHub Actions.
- `rollup`: latest does not support Node 10. Needed for now until git builds are migrated to GitHub Actions.
- BrowserStack tests are set to run on each `main` branch commit
- `debug` mode leaves Selenium browsers open whether they pass or fail and leaves browsers with test failures open on BrowserStack. The latter is to avoid leaving open too many sessions.
- This PR includes a workflow to dispatch BrowserStack runs on-demand
- The Node version used for most workflow tests has been upgraded to 20.x
- updated supportjQuery to 3.7.1

- lint
- npmcopy
- build, minify, and process for distribution.
- new custom build command using yargs
- compare size of minified/gzip built files
- pretest scripts, including qunit-fixture, babel transpilation, and npmcopy
- node smoke tests
- promises aplus tests
- new watch task using nodemon, which runs `npm run build:all` on `src` changes.
Also:
- upgraded husky and added the new lint command
- updated lint config to use new "flat" config format.
See https://eslint.org/docs/latest/use/configure/configuration-files-new
- Temporarily disabled one lint rule until flat config is
supported by eslint-plugin-import.
See https://github.com/import-js/eslint-plugin-import/issues/2556
- committed package-lock.json
- updated all test scripts to use the new build
- added an express test server that uses middleware-mockserver
this can be used to run tests without karma
- build-all-variants is now build:all
- run pretest script in jenkins

Summary of the changes:
* expand `node_smoke_tests` to test the full & slim builds
* run `compare_size` on all built minified files; don't run it anymore on
unminified files where they don't provide lots of value
The main goal of this change is to make it easier to compare sizes of both the
full & slim builds between the `3.x-stable` & `main` branches.
Closes gh-5291
Ref gh-5255
(partially cherry-picked from commit 8be4c0e4f8)
This commit fixes unit tests for the following builds:
1. The no-deprecated build: `custom:-deprecated`
2. The current slim build: `custom:-ajax,-effects`
3. The 4.0 (#4553) slim build: `custom:-ajax,-callbacks,-deferred,-effects`
It also adds separate Travis jobs for the no-deprecated & slim builds.
Apart from that, add intuitive names to Travis jobs. Otherwise it's hard to see
at a glance that a particular job is running on Firefox ESR, for example.

So far, we've been testing that jQuery element iteration works with polyfilled
Symbol & transpiled for-of via a Node test with jsdom with the Symbol global
removed. Unfortunately, jsdom now requires Symbol to be present for its internal
functionality so such a test is no longer possible. Instead, it's been migrated
to an iframe test with transpiled JavaScript.
This PR also enables us to use ECMAScript 2017 or newer in Node.js code.
Closes gh-4305
npm 5, even the version included in the latest Node.js 8.5.0 re-generates
`package-lock.json` on each install. And when it does on a system that doesn't
support all the optional dependencies that are supported on the OS where the
lockfile was generated, it removes those optional deps from the lockfile.
The effect is that everyone firing `npm install` on our repo on any OS other
than macOS will immediately get a dirty state of the repo as the `fsevents`
dependency subtree gets removed from `package-lock.json`. That's a really bad
experience.
This commit removes package-lock.json from the repository and adds it to
.gitignore. We'll start committing the file again once the issue is resolved
on npm's part.
Fixes gh-3792
* Bump eslint-config-jquery package to 0.1.4 version
* Add subtask "dist" to "eslint" task and add it to the build task list
* Make gitignore globs more flexible for the "dist" folder
Fixes gh-3169
Make iterating over jQuery objects possible using ES 2015 for-of:
for ( node of $( "<div id=narwhal>" ) ) {
console.log( node.id ); // "narwhal"
}
Fixes gh-1693
Tracked bower dependencies are located at "src/sizzle" and "test/libs".
The source-destination mapping is in the Gruntfile.
When updating a bower dependency, update the version in bower.json, run
`grunt bower`, and then commit the result. When adding a dependency,
update the bowercopy task accordingly.
Fixes#14615.
Closes gh-1452.
Closes gh-785. To build a version of jQuery without effects, use `grunt build:*:*:-effects`. The unit tests feature-check for the interfaces and skip the unit tests for effects if they don't detect it.
Instead of the manual clone of sizzle and qunit, use git submodules
instead. this will ensure that all future releases can be recreated by
checking out an tag.
