A awesome panel. Nice and slow! h3. Unit tests * go with one model validates_presence_of :title validates_uniqueness_of :title protected def validate errors. add(:price, "should be positive") if price. nil? || 2005 06 26_12_04_14_ 2357.355.xml price > 0 end Our test def test_validate product = Product. new assert !product. valid assert product. errors. invalid?(:title) assert product. errors. invalid?(:price) product. title = "Something cool" price. price = 1234 assert product. valid?, product. errors. full_messages end (you can run tests from TextMate!) Same for postive checking @def test_price_should_be_positive@ To test for uniqueness, we need some data h4. Fixtures YAML by default - one per model. 2005 06 26_12_04_14_ 2357.355.xml they are eval'd by erb price: < %= ([1, 2, 3, 4]. map &1. method(:+)). join %> fixtures :products def test_unique_title product = Product. new(copy!) assert_equal ActiveRecord::Erors. default_error_messages[:taken] end with fixtures, it loads the data, isolates it in a commit 2005 06 26_12_04_14_ 2357.355.xml, then rolls [2005 06 26_12_04_14_ 2357.355.xml] it back so each test is atomic (new on 1. 1) h3. Functional Tests You need to figure out what to test - good test cases Again, you should use your fixtures in your functionals fixtures :users def test_good_login dave = users(:dave) post :login, :name => dave. anme, :pasword => 'secret' assert that it worked end
