Calling instance_of will cause all instances of the passed in Class to have the Double defined.
The following example mocks all User’s valid? method and return false.
mock.instance_of(User).valid? {false}
The following example mocks and proxies User#projects and returns the first 3 projects.
mock.instance_of(User).projects do |projects| projects[0..2] end
