karma + mocha + should v7 不工作 - should 未定义

Question

我正在尝试配置 karma + mocha + should，但我一定遗漏了一些东西，因为 should 在我的测试中未定义。

根据 plugin documentation，唯一需要遵循的步骤是：

1.- Add should to frameworks and karma-should to plugins keys in your karma configuration:

module.exports = function(config) {
  config.set({
    frameworks: ['mocha', 'should'],
    plugins: ['karma-should']
  });
};

All should assertions are available in the tests

这是我的配置：

package.json

"devDependencies": {
    "karma": "^0.13.3",
    "karma-chrome-launcher": "^0.2.0",
    "karma-firefox-launcher": "^0.1.6",
    "karma-mocha": "^0.2.0",
    "karma-phantomjs-launcher": "^0.2.0",
    "karma-requirejs": "^0.2.2",
    "karma-should": "0.0.1",
    "mocha": "^2.2.5",
    "should": "^7.0.2",
  }

karma.conf.js

config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: '',


    // frameworks to use
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    frameworks: ['mocha', 'should'],

    plugins: ['karma-mocha',
              'karma-should',
              'karma-chrome-launcher',
              'karma-firefox-launcher'],

simpleTest.js

describe('theAnswer()', function() {
  it('should be 42', function() {
    theAnswer().should.be.exactly(42);
  });
});


function theAnswer() {
  return 42;
}

当我运行 karma start 我得到：

Firefox 39.0.0 (Windows 7 0.0.0) theAnswer() should be 42 FAILED
    theAnswer(...).should is undefined

知道为什么吗？

Answer 1

由于 should 7.x.x:

中的包更改，这似乎是插件实现的问题

有一个开放的拉取请求： https://github.com/seegno/karma-should/pull/1

当前插件版本 (0.0.1) 应该 6.x.x。

编辑： 最新的 karma-should 插件版本 (1.0.0) 纠正了这个问题。
