TLDR

In this post I will explain how to use rspec expectations in cucumber project that uses page object gem.

In order to be able to use rspec expectations in cucumber project, you first have to include rspec gem in your Gemfile. After that, you have to put in

When you think about it, this is logical decision. Page object class should represent page that you interact with with methods that interact with page elements.

For me, that was not obvious so I hope that this post would save you some time.
