Testing an options hash receives certain parameters

This method is very useful for testing methods that use the ruby idiom of accepting a hash with configurable options.

class Example
  def self.find(options = {})

We can use hash_including to ensure that certain options are passed in when mocking it.

Example.should_receive(:find).with(hash_including(:conditions => 'some conditions'))

Example.find(:conditions => 'some_conditions', :order => 1)
# => Passes expectation

Example.find(:order => 1)
# => Fails expectation

This can also be used to great effect with the anything matcher. For example:

hash_including(:key => anything)

hash_including(anything => 'value')
