How do I obtain the browser context of a window opened by an Electron app using Playwright?

Answer

Obtain the Browser Context of a Window Opened by an Electron App

To get the browser context of a window opened by an Electron app using Playwright, follow these steps:

1. Launch the Electron app: Use the electron.launch() method to launch an instance of your Electron app.

   import { electron } from '@playwright/test';
   
   const electronApp = await electron.launch({ args: ['--app-path', 'path/to/your/app'] });

2. Listen for new windows: Use the on('window') event to listen for new windows created and loaded in your app. This event provides a Page object for Playwright automation.

   let mainWindow: Page;
   electronApp.on('window', async (window: Page) => {
     mainWindow = window;
   });

3. Get the browser context: Use the context() method of the ElectronApplication instance to get the browser context.

   const browserContext = electronApp.context();

Now you have the browser context of the window opened by your Electron app, and you can use it for setting up context-wide routing or other tasks.

Remember to close the Electron app using the close() method when you're done interacting with it:

await electronApp.close();

By following these steps, you can effectively obtain the browser context of a window opened by an Electron app using Playwright.
