Overview

This class represents a series of requests issued to a Rack app, sharing a single cookie jar

Rack::Test::Session’s methods are most often called through Rack::Test::Methods, which will automatically build a session when it’s first used.

Constructor Details

#initialize(mock_session) ⇒ Session

Creates a Rack::Test::Session for a given Rack app or Rack::MockSession.

Note: Generally, you won’t need to initialize a Rack::Test::Session directly. Instead, you should include Rack::Test::Methods into your testing context. (See README.rdoc for an example)
