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.
