Testing uniqueness validation

Question

I'm trying to learn rspec and have ran into a problem, I'm trying to test the uniqueness validation on one of my models, but the test keeps failing even though I'm pretty sure it should pass.

Here is my test:

  context "two products with the same title" do
    Given{FactoryGirl.build(:product, title: "Hello test title")}
    Given(:post2){FactoryGirl.build(:product, title: "Hello test title")}
    Then{post2.invalid?}
  end

and here is my validator:

validates :title, uniqueness: true

however when I run the test it comes back failed and I'm not sure why?

any help would be great!

Answer 1

You need to add uniqueness validation on title:

validates :title, uniqueness: true

And also you have to create first product not just build it

context "two products with the same title" do
  Given{FactoryGirl.create(:product, title: "Hello test title")}
  Given(:post2){FactoryGirl.build(:product, title: "Hello test title")}
  Then{post2.invalid?}
end

This will create one product with title = "Hello test title"

And for second product with same title product will be invalid
