This patch adds a general-purpose grid framework to parallelize
Playwright across multiple agents.
This patch adds two CLI commands to manage grid:
- `npx playwright experimental-grid-server` - to launch grid
- `npx playwrigth experimental-grid-agent` - to launch agent in a host
environment.
Grid server accepts an `--agent-factory` argument. A simple
`factory.js` might look like this:
```js
const child_process = require('child_process');
module.exports = {
name: 'My Simple Factory',
capacity: Infinity, // How many workers launch per agent
timeout: 10_000, // 10 seconds timeout to create agent
launch: ({agentId, gridURL, playwrightVersion}) => child_process.spawn(`npx`, [
'playwright'
'experimental-grid-agent',
'--grid-url', gridURL,
'--agent-id', agentId,
], {
cwd: __dirname,
shell: true,
stdio: 'inherit',
}),
};
```
With this `factory.js`, grid server could be launched like this:
```bash
npx playwright experimental-grid-server --factory=./factory.js
```
Once launched, it could be used with Playwright Test using env variable:
```bash
PW_GRID=http://localhost:3000 npx playwright test
```
The common pattern today is to have two commands to configure CI:
```sh
npx playwright install-deps chromium
npx playwright install chromium
```
With this patch, this becomes:
```sh
npx playwright install --with-deps chromium
```
Note: `--with-deps` might call `sudo`.
- 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.
