In my controller spec I am doing this:

it "should create new message" do
  Client.should_receive(:create).with({:title => 'Mr'})
  post 'create' , :client => {:title => "Mr" }
end

... and in my controller I am doing ...

def create
  client = Client.create(params[:client])
end

However this is failing with the following error message :

  expected: ({:title=>"Mr"})
       got: ({"title"=>"Mr"})

I'm wondering why this is happening and how to get it to work
