Review suggestions for #613

[jayaddison]

• Add some test coverage
• ...partly to explain omitting elements with attribute class (I was trying to figure this out during code review)
• Code style fixups

This made me think that it feels less straightforward than it should be to add multiple test cases per scraper.

This made me think that it feels less straightforward than it should be to add multiple test cases per scraper.

to be honest I just ran out of time and forgot about it afterwards, there are plenty of examples of having multiple test cases. Its just a bit renaming.

I like the changes, feel free to merge them and just close my PR as yours contains my changes already. If want to do me a favor add a label called hacktoberfest-accepted to my PR as I am participating in hacktoberfest and it would be great if it counts :)
Btw. hacktoberfest is really cool, I have been participating the last 6 years or so and its always a welcome occasion to work on something completely different and they send out a really nice shirt https://hacktoberfest.com/
