context – The testing library you’ve been looking for

github.com/jeremymcanally/context

DESCRIPTION:

If you’ve ever wanted contexts in your Test::Unit tests, then context is for you. Your tests will be easier to read and write without all the magic and extra code smell!

FEATURES/PROBLEMS:

• Add contexts to Test::Unit tests
• Small DSL for specifying tests that are pretty
• Ability to chain context lifecycle methods (coming soon)

SYNOPSIS:

• Add contexts using familiar syntax:

      class UserTest < Test::Unit::TestCase
        context "A new User" do
          # Before/after lifecycle blocks
          before do
            @user = User.first
          end
  
          # Specify tests using DSL
          test "should have the right full_name" do
            assert_equal "Dude Man", @user.full_name
          end
  
          test "should be able to set parts of the name" do
            @user.first_name = "Mad"
            @user.last_name = "Max"
            @user.save
            assert_equal "Mad Max", @user.full_name
          end
  
          after do
            @user.first_name = "Dude"
            @user.last_name = "Man"
            @user.save!
          end
        end
      end
  

• It also has aliases that match other library’s syntaxes (all of which can be mixed and matched):

      class UserTest < Test::Unit::TestCase
        context "A new Account" do
          test "should be new" do
            Account.new.new_record?
          end
        end
  
        # RSpec-esque
        describe "A new User" do
          it "should do things" do
            User.first.do_things!
          end
        end
  
        # Shoulda-esque
        context "Another User" do
          should "do things that are fun" do
            User.first.do_things!(:fun)
          end
        end
      end
  

• Contexts can also be nested:

    class UserTest < Test::Unit::TestCase
      context "A new User" do
        context "with clown shoes" do
          test "should squeak" do
            assert_true User.find_by_shoes("clown").squeak?
          end
        end
  
        context "without clown shoes" do
          test "should not squeak" do
            assert_false User.find_by_shoes("dressy").squeak?
          end
        end
      end
    end
  

• You can also share behavior among contexts:

    class UserTest < Test::Unit::TestCase
      shared "shared things" do
        test "things are shared" do
          # test logic here...
        end
      end
  
      context "the first thing" do
        uses "shared things"
  
        test "other things..." do
          # More testing...
        end
      end
    end
  

• Shared behaviors can also use RSpec syntax

    class UserTest < Test::Unit::TestCase
      share_examples_for "shared things" do
        it "things are shared" do
          # test logic here...
        end
      end
  
      describe "the first thing" do
        it_should_behave_like "shared things"
  
        it "other things..." do
          # More testing...
        end
      end
    end
