why attr_accessor here instead of attr_reader or attr_writer?

Do your tests pass when you run rspec?

why might grouping your tests into contexts be a good idea?

Take another look at betterspecs.org to see how contexts are used. Remember to run your rspec tests to ensure they run.

I like this. There's a couple of other ways to do this as well.

The documentation spells out your method here.

For things like this, we use let. Refactor any variables used here using let instead.

This works. You could also use .times which would make this cleaner.
