You have specified that your model's #{attribute} should ensure inclusion of nil.
However, #{attribute} is a boolean column which does not allow null values.
Hence, this test will fail and there is no way to make it pass.

The validation failed because your #{model_name} model declares `has_secure_password`, and

Please use a #{record_name} with an empty `password` instead.
