Trying to implement a couple tests for my custom validations and I came across this example.

My validator looks like this

class FutureValidator < ActiveModel::EachValidator
  def validate_each(record, attribute, value)
    if value == nil
      record.errors[attribute] << " can't be nil"
    elsif value < Time.now
      record.errors[attribute] << (options[:message] || "can't be in the past!")
    end
  end
end

And I've gotten as far as this using the above mentioned example as a guideline. 

require 'test_helper'

class FutureValidatorable
  include ActiveModel::Validations
  # validates_with FutureValidator
  attr_accessor :future

  validates :future, future: true
end

class FutureValidator < ActiveSupport::TestCase

  future_value = [nil]
  def obj; @obj ||= FutureValidatorable.new; end

  test 'future validator returns proper error code when nil is passed to it' do
    future_value.each do |value|
      @obj.value = value
      assert_not obj.valid?
    end
  end

At this stage I'm getting the error message I am getting is as follows.

rake aborted! TypeError: superclass mismatch for class FutureValidator

I'm not sure how to proceed from here.

Looks like your model and TestCase have the same class name. Changing the name of your test should fix the issue.

  • Good catch. I just noticed that 5 seconds before you posted this answer. – CheeseFry Apr 08 '16 at 19:35
  • Any suggestions on how to get a workable test on this one? `NoMethodError: undefined method `value=' for nil:NilClass` is my current error message on the test. – CheeseFry Apr 08 '16 at 19:36
  • looks like your `obj` method isn't being called. Either use `obj` instead of `@obj` in your Test Case, or declare it within a `def setup` method of the test. – Anthony E Apr 08 '16 at 19:47
