Selecting multiple options using Laracasts\Integrated

I am using Laracasts\Integrated library to test my web application. I have a form like this:

<select multiple name="resource[]"> 
<option value="Coal">Coal</option>
<option value="Another">Aluminum</option>
.
.
</select>

My test case is:

$this->select('resource[]' , ['Coal' , 'Another']);

i get error:

Symfony\Component\CssSelector\Exception\SyntaxErrorException:  Expected identifier│ or "*", but <delimiter "]" at 11> found.

Please help me .
