Two things I noticed in your code:
The twitter-button should be an a tag, so remove the div .
And I couldn’t find any specific option to retrieve the text inside your JS file. Might want to take a look at it.
I actually encountered a similar problem when I was doing the project. Funny thing is sometimes the test were passing even though my Quotes weren’t showing up.
In my case I defined an Array of Quotes & Authors , then tried to retrieve from that array.
