Instance Method Details

#copy_session_variables!Object

Copy the instance variables from the current session instance into the test instance.

def copy_session_variables! #:nodoc:
  return unless @integration_session
  %w(controller response request).each do |var|
    instance_variable_set("@#{var}", @integration_session.__send__(var))
  end
end

#open_session {|session| ... } ⇒ Object

Open a new session instance. If a block is given, the new session is yielded to the block before being returned.

session = open_session do |sess|
  sess.extend(CustomAssertions)
end

By default, a single session is automatically created for you, but you can use this method to open multiple sessions that ought to be tested simultaneously.

Yields:

  • (session)

end
