shoulda-context Gem Version Build Status

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.


Instead of writing Ruby methods with lots_of_underscores, shoulda-context adds context, setup, and should blocks...

require "test/unit"

class CalculatorTest < Test::Unit::TestCase
  context "a calculator" do
    setup do
      @calculator = Calculator.new

    should "add two numbers for the sum" do
      assert_equal 4, @calculator.sum(2, 2)

    should "multiply two numbers for the product" do
      assert_equal 10, @calculator.product(2, 5)

... 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."

When running a single test method via (example from a Rails context):

ruby -I"lib:test" path_to_test_file -n name_of_the_test_method

you should include a trailing space(!), e.g.,

ruby -I"lib:test" path_to_test_file -n "test: a calculator should add two numbers for the sum. "


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')
