- Add the ability to retry by restarting the worker and
getting a different browser instance, after all
normal retries have been exhausted. This can sometimes
be successful when a refresh is not.

- reuse BrowserStack workers.
- add support for "latest" and "latest-1" in browser version filters
- add support for specifying non-final browser versions, such as beta versions
- more accurate eslint for files in test/runner
- switched `--no-isolate` command flag to `--isolate`. Now that browser instances are shared, it made more sense to me to default to no isolation unless specified. This turned out to be cleaner because the only place we isolate is in browserstack.yml.
- fixed an issue with retries where it wasn't always waiting for the retried test run
- enable strict mode in test yargs command
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 Runner
- 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
- 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.
- cleans up after itself (closes the local tunnel, stops the test server, etc.)
- Requires `BROWSERSTACK_USERNAME` and `BROWSERSTACK_ACCESS_KEY` environment variables.
## Selenium Runner
- 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
Run `npm run test:unit -- --help` for CLI documentation

Node.js 20 started throwing errors when `writeHead` is called twice on
a response. This might have already been invalid before but it wasn't throwing
on Node.js 18.
Compute the headers object and call `writeHead` once to avoid the issue.

- also add the ability to pass VERSION in env to test final builds
- adjust sha regex to account for lack of shas
- set the version on the dist package.json

The `attrHooks` entries for boolean attributes are only defined for jQuery 4+;
jQuery 3.x used a separate mechanism - assigning them to
`jQuery.expr.attrHandle`. That object used to be maintained by Sizzle, since
jQuery 3.7.0 it's kept in the selector module. Because of that, the `isXMLDoc`
check used to be require in this hook.
Now that standard `attrHooks` are used, the `isXMLDoc` check already happens
inside of `jQuery.attr` and there's no need to repeat it in the test. Note that
this repetition is even incorrect - while Sizzle's `jQuery.find.attr` used to
treat an `undefined` output of the hooks from `jQuery.expr.attrHandle` as a way
to opt out of the hook, jQuery's `attrHooks` use `null` to opt out of a getter
hook.
Apart from the size, this patch also avoids unnecessary extra checks.
Closes gh-5398
This fixes custom builds using the `--include` switch that don't include
the `attributes` module.
Fixes gh-5379

There are two main reasons for why some of those dependencies are no longer
needed:
1. `jQuery.contains` which is now a part of `core`.
2. `jQuery.find.attr` no longer exists, native `getAttribute` is used instead.

Use Prettier 3.1.0 to reformat the Yaml files. This makes their format identical
to the one used on `3.x-stable`, making for much easier cherry-picks.
The main difference is the list under `steps:` was not indented while all other
lists were.
Closes gh-5364
Build was already happening in scripts like `test:browser` but those scripts
were missing `pretest`, meaning that running `npm install && npm test:browser`
may have failed if `pretest` wasn't run before or if its results were out of
date.
Even worse, with such stale data some tests may erroneously succeed.
This also removes a separate `pretest` step from GitHub Actions as it's no
longer needed.
Closes gh-5338
The package README used to show examples importing from a regular jQuery file;
this won't work natively. Instead, use module versions of jQuery in these
examples.
Closes gh-5336
Bring some changes from `3.x-stable`:
* rename `rtrim` to `rtrimCSS` to distinguish from the previous `rtrim`
regex used for `jQuery.trim`
* backport one `id` selector test that avoids the selector engine path
Other changes:
* remove the inner function wrapper from `selector.js` by renaming
the imported `document.js` value
* use `jQuery.error` in `selectorError`
* make Selector tests pass in all-modules runs by fixing a sinon mistake
in Core tests - Core tests had a spy set up for `jQuery.error` that wasn't
cleaned up, influencing Selector tests when all were run together
Closes gh-5295
Summary of the changes:
* Core: Simplify code post browser support reduction
* Tests: Remove legacy jQuery.cache & oldIE leftovers
* Tests: Reformat JavaScript in delegatetest.html
* Docs: "jQuery Foundation Projects" -> "jQuery Projects"
* Tests: Drop an unused localfile.html file (modern browsers don't support
the `file:` protocol this way, there's no point in keeping the file around)
* Effects: Remove a redundant `!fn` check (`fn || !fn && easing` is equivalent
to `fn || easing`; simplify the code)
* CSS: Explain the fallback to direct object access in curCSS better
* Tests: Deduplicate `jQuery.parseHTML` test titles
* Dimensions: Add a test for fractional values
* Tests: Fix a buggy WebKit regex
Closes gh-5296
Since versions 1.11.0/2.1.0, jQuery has used a module wrapper with one strange
addition - in CommonJS environments, if a global `window` with a `document` was
not present, jQuery exported a factory accepting a `window` implementation and
returning jQuery.
This approach created a number of problems:
1. Properly typing jQuery would be a nightmare as the exported value depends on
the environment. In practice, typing definitions ignored the factory case.
2. Since we now use named exports for the jQuery module version, it felt weird
to have `jQuery` and `$` pointing to the factory instead of real jQuery.
Instead, for jQuery 4.0 we leverage the just added `exports` field in
`package.json` to expose completely separate factory entry points: one for the
full build, one for the slim one.
Exports definitions for `./factory` & `./factory-slim` are simpler than for `.`
and `./slim` - this is because it's a new entry point, we only expose a named
export and so there's no issue with just pointing Node.js to the CommonJS
version (we cannot use the module version for `import` from Node.js to avoid
double package hazard). The factory entry points are also not meant for the Web
browser which always has a proper `window` - and they'd be unfit for an
inclusion in a regular script tag anyway. Because of that, we also don't
generate minified versions of these entry points.
The factory files are not pushed to the CDN since they are mostly aimed
at Node.js.
Closes gh-5293
