Riot.js:快速的JavaScript单元测试框架

Riot是一个快速，富有表现力，上下文驱动 的单元测试框架。最初是用于Ruby的单元测试，最近作者Alex Young又实现了Riot的JavaScript版- Riot.js。

示例：

context "a new user" do
  setup { User.new }
  asserts("that it is not yet created") { topic.new_record? }
end

Riot.run(function() {
  context('basic riot functionality', function() {
    given('some simple equality tests', function() {
      asserts('a simple truth test should return true', true).isTrue();
      asserts('isNull is null', null).isNull();
    });
 
    given('another context', function() {
      asserts('equals should compare strings as expected', 'test string').equals('test string');
    });
 
    given('a context concerned with functions', function() {
      asserts('asserts() should allow functions to be compared', function() {
        return 'test string';
      }).equals('test string');
    });
  });
 
  given('yet another context', function() {
    asserts('equals should compare strings as expected', 'test string').equals('test string');
  });
});
