Okay, I realised the with() is calling the == method on whatever you pass in, so I did this:

      module EquateAnyHashContainingAllMyElements
        def ==(other)

          self.keys.all? do |key|
            other.has_key?(key)
          end

        end
      end
        ....

          expected_params = {
            :page => "1",
            :city_id => city.id.to_s,
            :name => name_filter }

          expected_params.extend(EquateAnyHashContainingAllMyElements)

Venue::Query.should_receive(:new).with ( expected_params ).and_return(query)


Thoughts? Is there a neater way to do this? Be as brutal as you like ... ;)

cheers,
Matt

Hi folks,

I have an object whose constructor I want to stub, specifying that it should be passed a hash containing an expected set of key / value pairs.

Note that the actual hash might contain more key / value pairs, but I don't care, as long as my expected ones are there

I thought I might be able to write this:

          expected_params = {
            :page => "1",
            :city_id => city.id.to_s,
            :name => "thingy" }

Venue::Query.should_receive(:new).with( include (expected_params) ).and_return(query)

... but it doesn't seem to work.

What's my best approach?

Thanks for your patience and support as I get up to speed with this stuff folks. You're all very kind!

cheers,
Matt
