instance method
test_errors_aref
Ruby on Rails 5.1.7
Since v3.0.20Signature
test_errors_aref()Passes if the object’s model responds to errors and if calling [](attribute) on the result of this method returns an array. Fails otherwise.
errors[attribute] is used to retrieve the errors of a model for a given attribute. If errors are present, the method should return an array of strings that are the errors for the attribute in question. If localization is used, the strings should be localized for the current locale. If no error is present, the method should return an empty array.
