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_accumulate_when_block_is_deferred
skip
accumulate_enumerator = [1, 2, 3].accumulate
accumulated_result = accumulate_enumerator.each do |number|
number * number
end
assert_equal [1, 4, 9], accumulated_result
end
```
