- Source now lives at `src/test`.
- Former folio tests live at `tests/playwright-test`.
- We use `src/test/internal.ts` that exposes base test without
Playwright fixtures for most tests (to avoid modifications for now).
- Test types live in `types/testFoo.d.ts`.
- Stable test runner is installed to `tests/config/test-runner` during `npm install`.
- All deps including test-only are now listed in `package.json`.
Non-test deps must also be listed in `build_package.js` to get included.
This changes the root object from RemoteBrowser to Playwright,
similar to local driver connection. This way, any remote connection
gets a Playwright object.
This also starts reusing PlaywrightServer class, and introduces
`cli run-server` hidden command that runs ws server on the
specified port.
Previous structure:
```
RemoteBrowser
- browser (using ConnectedBrowser for remote-specific behavior)
- selectors (special instance for this remote connection)
```
New structure:
```
Playwright
- ...
- selectors (special instance for this remote connection)
- preLaunchedBrowser (using ConnectedBrowser for remote-specific behavior)
```
This patch adds support for `technology preview` webkit channel, which
we will keep close to the actual Safari Technology Preview releases.
This channel does not install by default. It is supposed to be installed
with the following CLI command:
```sh
$ npx playwright install webkit-technology-preview
```
Once the channel is installed, it can be used the following way:
```js
const browser = await playwright.webkit.launch({
channel: 'technology-preview',
});
```
**NOTE:** if clients attempt using the channel without installing it,
it'll throw an error with a copyable instructions to install via CLI.

This makes dialogs disappear and prevents stalling.
Pros:
- No need to worry about dialogs for most users.
- Those that wait for a specific dialog still get to control it.
Cons:
- Those who use Playwright to show interactive browser will have
to add an empty 'dialog' handler to prevent auto-dismiss.
We do this in cli.
Everything but attributes in the light dom is manually compared during
DOM traversal, for example child nodes or scroll offset.
This way we get a bullet-proof solution that works with input values,
scroll offsets, shadow dom and anything else web comes up with.
We also restore scroll only on the document scrolling element, for
performance reasons. We should figure out the story around scrolling.
Changes stationary snapshots from ~0.5ms to ~2.5ms due to DOM traversal.
- Intercept CSSOM modifications and recalculate overridden css text.
- When css text does not change, use "backwards reference" similar
to node references.
- Set 'Cache-Control: no-cache' for resources that could be overridden.
- Switch from html to json ml format.
- Allow node reuse between snapshots with `[nSnapshotsBefore, nodeWithIndexM]`.
- Service worker now lazily serializes snapshot chunks into a single html.
This decreases total snapshot size on random scripts ~10x.
This also decreases snapshot collecting time on mostly static pages to ~0.3ms.
Unfortunate downside for now is that we have to intercept
`Element.prototype.attachShadow` to invalidate nodes. This
also temporary breaks scroll restoration. Needs more research.
- Move service worker under /snapshot/ instead of /.
- Fix stylesheet base uri bug, where we inherited the wrong base url.
- Introduce TraceServer and routes there, split the actual routes
between snapshot, ui and action previews.
