Selenium Grid
=====================

As well as JSONWire protocol bindings, Webdriverio also offers a few utility commands for working with the Selenium Grid. It's often useful to know the details of the Grid node which is actually running the current session. Use `getGridNodeDetails()` to get a JSON object with details like ID, hostname and port, configured timeouts, plus any command-line params used to start the node.

```js
client.getGridNodeDetails().then(function(details) {
     console.log(details);
     /**
