RSpec 3 is a major release of the Behaviour-Driven Development tool for Ruby programmers.

RSpec 3 introduces many new features and also removes some syntax from RSpec 2. The last release of RSpec 2, RSpec 2.99, deprecates the removed syntax as an aid to upgrading to RSpec 3.

As with all tags with version numbers, please use this tag only for questions which are actually specific to RSpec 3, and always tag such questions with the non-versioned tag as well as with this tag.
