| // These tests test WebSocket handshake throttling, which is a feature of |
| // Blink's implementation, not part of the web platform. The special throttle |
| // content::TestWebSocketHandshakeThrottle is used when content_shell is run |
| // with the --run-web-tests option. It detects the |
| // content-shell-websocket-delay-ms query parameter in the URL and applies a |
| // delay of the specified number of milliseconds. |
| // |
| // These tests will not function correctly without the --run-web-tests |
| // option. To debug them interactively you can follow the instructions for a |
| // "legacy test" in |
| // https://chromium.googlesource.com/chromium/src/+/master/docs/testing/web_tests.md#Debugging-DevTools-Tests. |
