How can this be possible: I have two tests: def find_all_active_and_inactive assert_equal Concept.find_all_active_and_inactive.size, @concepts.size end and def test_find_all_inactive assert_equal Concept.find_all_inactive.size, (@concepts.size - Concept.find_all.size) end Concept.find_all returns 2 concepts (I overwrote the method to return only the active concepts) Concept.find_all_inactive returns 1 concept Concept.find_all_active_and_inactive returns 3 concepts And @concepts.size returns 3 When I run the first test, there is no error. When I run the second test, I get this error: 1) Error: test_find_all_inactive(ConceptTest): NoMethodError: You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occured while evaluating nil.size concept_test.rb:36:in `test_find_all_inactive' I dont understand! Why is @concepts.size working in the first test and not in the second?
