De-register all shared workers #3151

@codetheweb codetheweb commented Dec 19, 2022

This fixes the bug introduced in #3149 that I briefly mentioned.

Since we were assigning the launched shared worker to a single variable per test worker, we inadvertently assumed that a test worker would launch a maximum of 1 shared worker.

I tested this patch with two of our internal codebases that heavily use shared workers and everything's working as expected now.

Sorry for the previous buggy PR!

Thanks for the follow-up @codetheweb! I haven't touched a keyboard much these past few weeks but hopefully I can find some time soon. Of course it's back to work so busy busy again 😄

@codetheweb thoughts on the commit I pushed up?

Thanks for adding all these test cases, it's pretty hard to think about the expected behavior.

Looks perfect to me! Much clearer on what's going on.

### Release Notes

<details>
<summary>avajs/ava (ava)</summary>

### [`v6.0.0`](https://togithub.com/avajs/ava/releases/tag/v6.0.0)

[Compare Source](https://togithub.com/avajs/ava/compare/v5.3.1...v6.0.0)

#### Breaking Changes

- AVA now requires Node.js versions 18.18, 20.8 or 21. Versions 14 and
16 are no longer supported.
[#&#8203;3251](https://togithub.com/avajs/ava/issues/3251)
[#&#8203;3216](https://togithub.com/avajs/ava/issues/3216)

- When tests finish, worker threads or child processes are no longer
exited through `proces.exit()`. If your test file does not exit on its
own, the test run will time out.
[#&#8203;3260](https://togithub.com/avajs/ava/issues/3260)

- Changes to watch mode
[#&#8203;3218](https://togithub.com/avajs/ava/issues/3218):
- Watch mode can no longer be started via the `ava.config.*` or
`package.json` configuration.
- The `ignoredByWatcher` configuration has moved to the `watchMode`
object, under the `ignoreChanges` key.
- Watch mode now uses the built-in
[`fs.watch()`](https://nodejs.org/api/fs.html#fswatchfilename-options-listener)
in recursive mode. This is supported on Linux in Node.js 20 or newer,
and MacOS and Windows in Node.js 18 as well. There are
[caveats](https://nodejs.org/api/fs.html#caveats) to keep in mind.

- Failed assertions now throw, meaning that any subsequent code is not
executed. This also impacts the type definitions.
[#&#8203;3246](https://togithub.com/avajs/ava/issues/3246)

- [Only native
errors](https://nodejs.org/api/util.html#utiltypesisnativeerrorvalue)
are now considered errors by the `t.throws()` and `t.throwsAsync()`
assertions. [`Object.create(Error.prototype)` is **not** a native
error](Object.create\(Error.prototype\)).
[#&#8203;3229](https://togithub.com/avajs/ava/issues/3229)

- Changes to modules loaded through the `require` configuration
[#&#8203;3184](https://togithub.com/avajs/ava/issues/3184):
- If such modules export a default function, this function is now
invoked.
    -   Local files are loaded through `@ava/typescript` if necessary.

#### Improvements

##### Rewritten watcher

The watcher has been rewritten. It’s now built on
[`fs.watch()`](https://nodejs.org/api/fs.html#fswatchfilename-options-listener)
in recursive mode.

[`@vercel/nft`](https://togithub.com/vercel/nft) is used to perform
static dependency analysis, supporting ESM and CJS imports for
JavaScript & TypeScript source files. This is a huge improvement over
the previous runtime tracking of CJS imports, which did not support ESM.

Integration with
[`@ava/typescript`](https://togithub.com/avajs/typescript) has been
improved. The watcher can now detect a change to a TypeScript source
file, then wait for the corresponding build output to change before
re-running tests.

The ignoredByWatcher configuration has moved to the watchMode object,
under the ignoreChanges key.

See [#&#8203;3218](https://togithub.com/avajs/ava/issues/3218) and
[#&#8203;3257](https://togithub.com/avajs/ava/issues/3257).

##### Failed assertions now throw

Assertions now throw a `TestFailure` error when they fail. This error is
not exported or documented and should not be used or thrown manually.
You cannot catch this error in order to recover from a failure, use
`t.try()` instead.

All assertions except for `t.throws()` and `t.throwsAsync()` now return
`true` when they pass. This is useful for some of the assertions in
TypeScript where they can be used as a type guard.

Committing a failed `t.try()` result now also throws.

See [#&#8203;3246](https://togithub.com/avajs/ava/issues/3246).

##### `t.throws()` and `t.throwsAsync()` can now expect any error

By default, the thrown error (or rejection reason) must be a native
error. You can change the assertion to expect any kind of error by
setting `any: true` in the expectation object:

```js
t.throws(() => { throw 'error' }, {any: true})
```

See [#&#8203;3245](https://togithub.com/avajs/ava/issues/3245) by
[@&#8203;adiSuper94](https://togithub.com/adiSuper94).

##### The `require` configuration is now more powerful

It now loads ES modules.

Local files are loaded through `@ava/typescript` if necessary, so you
can also write these in TypeScript.

If there is a default export function, it is invoked after loading. The
function is awaited so it can do asynchronous setup before further
modules are loaded. Arguments from the configuration can be passed to
the function (as a \[[structured
clone](https://developer.mozilla.org/en-US/docs/Web/API/structuredClone)]\(https://developer.mozilla.org/en-US/docs/Web/API/structuredClone)).

See [#&#8203;3184](https://togithub.com/avajs/ava/issues/3184) by
[@&#8203;sculpt0r](https://togithub.com/sculpt0r).

##### Other changes worth noting

- Internal events can now be observed (experimentally). See
[#&#8203;3247](https://togithub.com/avajs/ava/issues/3247) by
[@&#8203;codetheweb](https://togithub.com/codetheweb). It’s experimental
and undocumented.
- You can now use `t.timeout.clear()` to restore a previous
`t.timeout()`.
[#&#8203;3221](https://togithub.com/avajs/ava/issues/3221)
- Code coverage is flushed to disk at opportune moments.
[#&#8203;3220](https://togithub.com/avajs/ava/issues/3220)
