The statement  
products = find\_all\_by\_category\_id(category\_id)  
in the Product model is returning nil with rspec.  
I am expecting it to to return the stub that I provided it with. It does  
not also work with fixtures.

Product model

def self.find\_all\_meeting\_some\_criteria\_for\_category(category\_id)  
products = find\_all\_by\_category\_id(category\_id)  
products.each do |product|  
…  
end  
end

Product spec

it “should find products given a category” do  
product = mock\_model(Product, :id =\> 1, :category\_id =\> 1)  
Product.stub(!find\_all\_by\_category\_id).with(anything()).and\_return([product])  
Product.should\_receive(:find\_all\_meeting\_some\_criteria\_for\_category).with(product.category\_id)  
end
