I am testing a page that has a bootstrap progress bar using RSpec. How do I test the different Aria attributes in the Div?

```
<div class="progress-bar progress-bar-success" 
    role="progressbar"  
    aria-valuenow="40"  
    aria-valuemin="0"  
    aria-valuemax="100"  
    style="width: 40%"> 
</div>

```

I appreciate any help you can provide.

Thanks!
