 It is typical to call [#to_enum](http://ruby-doc.org/core-2.3.1/Object.html#method-i-to_enum) when defining methods for a generic Enumerable, in case no block is passed.
 
 Here is an additional test you could add:
 
 ```ruby
-def test_no_block_is_passed
+def test_accumulate_when_block_is_deferred
   skip
-  result = [1, 2, 3].accumulate
-  assert_instance_of Enumerator, result
+  accumulate_enumerator = [1, 2, 3].accumulate
+  accumulated_result = accumulate_enumerator.each do |number|
+    number * number
+  end
+  assert_equal [1, 4, 9], accumulated_result
 end
 ```
