This is valid when super_diff is not installed.
expect(ids).to match_array(single_id)
With super_diff installed it fails with
Failure/Error: expect(ids).to match_array(single_id)
NoMethodError:
undefined method `each_with_index' for "my_id":String
Did you mean? each_line
I had to update the test to
- expect(ids).to match_array(single_id)
+ expect(ids).to match_array([single_id])
