Is there any API documentation for Rspec such as Rails?
I would recommend RSpec Book . You can get a beta version of PDF, as the actual book is not yet available at the time of writing.
Of course, it covers BDD, Cucumber and others, but mostly RSpec. Poor documentation started on the official website , saying that RSpec is not so much. What I know from this book, and quick blog posts.
RSpec white papers available at relishapphttp://relishapp.com/rspec/
The documentation is not bad.
There is also clean API documentation, which is a little less useful. He participated inhttp://rubydoc.info/gems/rspec-core/2.6.4/RSpec
All this documentation is extracted from the source code, so if you are interested in looking at the documentation mixed with the code, you can check rspec from github.
They have documentation:http://rspec.info/documentation/
This is not as good as Rails, but it is the beginning.
In addition, some documents can be found here http://apidock.com/rspec
