Shoulda::ActiveRecord::Assertions

Public Instance Methods

assert_bad_value(object_or_klass, attribute, value, error_message_to_expect = nil) click to toggle source

Asserts that an Active Record model invalidates the passed value by making sure the error_message_to_expect is contained within the list of errors for that attribute.

assert_bad_value(User.new, :email, "invalid")
assert_bad_value(User.new, :ssn, "123", /length/)

If a class is passed as the first argument, a new object will be instantiated before the assertion. If an instance variable exists with the same name as the class (underscored), that object will be used instead.

assert_bad_value(User, :email, "invalid")

product = Product.new(:tangible => true)
assert_bad_value(product, :price, "0")
# File lib/shoulda/active_record/assertions.rb, line 59
def assert_bad_value(object_or_klass, attribute, value,
                     error_message_to_expect = nil)
  object = get_instance_of(object_or_klass)
  matcher = allow_value(value).
              for(attribute).
              with_message(error_message_to_expect)
  assert_rejects(matcher, object)
end
assert_good_value(object_or_klass, attribute, value, error_message_to_avoid = nil) click to toggle source

Asserts that an Active Record model validates with the passed value by making sure the error_message_to_avoid is not contained within the list of errors for that attribute.

assert_good_value(User.new, :email, "user@example.com")
assert_good_value(User.new, :ssn, "123456789", /length/)

If a class is passed as the first argument, a new object will be instantiated before the assertion. If an instance variable exists with the same name as the class (underscored), that object will be used instead.

assert_good_value(User, :email, "user@example.com")

product = Product.new(:tangible => false)
assert_good_value(product, :price, "0")
# File lib/shoulda/active_record/assertions.rb, line 35
def assert_good_value(object_or_klass, attribute, value, error_message_to_avoid = nil)
  object = get_instance_of(object_or_klass)
  matcher = allow_value(value).
              for(attribute).
              with_message(error_message_to_avoid)
  assert_accepts(matcher, object)
end
assert_save(obj) click to toggle source

Asserts that the given object can be saved

assert_save User.new(params)
# File lib/shoulda/active_record/assertions.rb, line 7
def assert_save(obj)
  assert obj.save, "Errors: #{pretty_error_messages obj}"
  obj.reload
end
assert_valid(obj) click to toggle source

Asserts that the given object is valid

assert_valid User.new(params)
# File lib/shoulda/active_record/assertions.rb, line 15
def assert_valid(obj)
  assert obj.valid?, "Errors: #{pretty_error_messages obj}"
end
