shoulda-context

Official Documentation

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.

Contexts

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 calculator should add two numbers for the sum."
"test: a calculator should multiply two numbers for the product."

Assertions

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')
