Installation

The gem is hosted on http://gemcutter.org.

config.gem 'assert_db_rejects'

Example

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
