javascript - 业力 + Mocha + 应该 v7 不工作 - 应该是未定义的

Question

我正在尝试配置 karma + mocha + Should，但我必须缺少一些东西，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 时，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？

由于 should 7.x.x 中的包更改，插件实现似乎存在问题:

有一个针对此的开放拉取请求: https://github.com/seegno/karma-should/pull/1

当前插件版本(0.0.1)最高可达 6.x.x。

编辑:最新的 karma-should 插件版本 (1.0.0) 纠正了此问题。
