Release Notes

microsoft/playwright-dotnet (Microsoft.Playwright)

v1.48.0

WebSocket routing

New methods Page.RouteWebSocketAsync() and BrowserContext.RouteWebSocketAsync() allow to intercept, modify and mock WebSocket connections initiated in the page. Below is a simple example that mocks WebSocket communication by responding to a "request" with a "response".

await page.RouteWebSocketAsync("/ws", ws => {
  ws.OnMessage(message => {
    if (message.Text == "request")
      ws.Send("response");
  });
});

See WebSocketRoute for more details.

UI updates

• New "copy" buttons for annotations and test location in the HTML report.
• Route method calls like Foute.FulfillAsync() are not shown in the report and trace viewer anymore. You can see which network requests were routed in the network tab instead.
• New "Copy as cURL" and "Copy as fetch" buttons for requests in the network tab.

Miscellaneous

• New method Page.RequestGCAsync() may help detect memory leaks.
• Requests made by APIRequestContext now record detailed timing and security information in the HAR.

Browser Versions

• Chromium 130.0.6723.19
• Mozilla Firefox 130.0
• WebKit 18.0

This version was also tested against the following stable channels:

• Google Chrome 129
• Microsoft Edge 129
