Connecting to Chrome
There are some cases when we need to connect to a ruining instance of chrome instead of starting a new one. For example to bypass reCaptcha we can solve it manually in Chrome and then run the tests on it.
In order to connect we need to start Chrome in command-line with remote-debugging-port parameter.
Next we navigate in the started browser to http://127.0.0.1:9222/json/version. On the page we can see a JSON object.
Obtaining webSocketDebuggerUrl
We shell copy the value of webSocketDebuggerUrl property. Open Run Tests modal window (F6), switch to Browser options tab and paste the saved value into WS Endpoint input.
