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
```
