Test database level constraints with ActiveRecord.

require 'test_helper' class PersonTest < ActiveSupport::TestCase test "database blocks duplicate names" do Person.create!( :name => "Test" ) # Assume the people table has a not null constraint on name. The assertion # will pass if a ActiveRecord::StatementInvalid is raised when saving p. # Validations are bypassed by assert_db_rejects as the purpose is to test # the database and not the model assert_db_rejects( Person.new( :name => "Test" ) ) end end
