I don't know what the expected way is to add the expect dependency in the test.
So all tests fail with Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'expect' imported from /home/runner/work/ava/ava/test/external-assertions/fixtures/expect-failure.js␊

Nice one @Irvenae!

Fixture packages are not installed, those package.json files are mostly there so that the AVA-under-test does not walk up to the repository root.

It should be fine if you install expect as a dev dependency.


Could you share some screenshots of how these errors are then reported? And could you address the linter errors?

not sure we want to expose that here or place this in a more appropriate file (or duplicate worst case)

It's available as Object.hasOwn() in Node.js 16 which will be the minimal required version soon enough. Repeating it is fine for now, I'm sure https://github.com/sindresorhus/eslint-plugin-unicorn will flag it soon enough 😉

Not sure how I should fix the windows tests. I could remove the snaps, but these give what we want to verify IMHO.

In that screenshot, is the syntax highlighting coming from Jest itself?

### 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.
