callback from selFunc on .end(cb) doesn't work with latest webdriverio

[jyoungqu]

Hi there,

Recently installed this package and the example script didn't work out of the box. The issue is with the webdriverio package and the apparent change to the .end() method not supporting a callback being passed to it.

I modified the code:
browser .init() .url(url) .end(cb);

to this:
browser .init() .url(url) .end() .call(cb);
