Shoulda's contexts make it easy to write understandable and maintainable tests for Test::Unit. It's fully compatible with your existing tests in Test::Unit, and requires no retooling to use.
Refer to the shoulda gem if you want to know more about using shoulda with Rails or RSpec.
Instead of writing Ruby methods with lots_of_underscores, shoulda-context adds context, setup, and should blocks…
class CalculatorTest < Test::Unit::TestCase context "a calculator" do setup do @calculator = Calculator.new end should "add two numbers for the sum" do assert_equal 4, @calculator.sum(2, 2) end should "multiply two numbers for the product" do assert_equal 10, @calculator.product(2, 5) end end end
… which combine to produce the following test methods:
"test: A User instance should return its full name." "test: A User instance with a profile should return true when sent #has_profile?."
It also has two additional Test::Unit assertions for working with Ruby's Array:
assert_same_elements([:a, :b, :c], [:c, :a, :b]) assert_contains(['a', '1'], /\d/) assert_contains(['a', '1'], 'a')
