Mocha interfaces: Uncaught ReferenceError: `describe` is not defined

Question

我正在使用 Gulp 与 mocha/sinon/chai 和 jquery

的运行业力

我的 karma.conf.js 有：

// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter
frameworks: ['jquery-2.1.0', 'mocha'],

// Plugin specific config
client: {
  mocha: {
    reporter: 'spec',
    ui: 'tdd'
  }
}

安装的节点模块是

"devDependencies": {
    "chai": "",
    "gulp": "",
    "gulp-jslint": "",
    "gulp-notify": "",
    "gulp-phpunit": "",
    "gulp-util": "",
    "karma": "",
    "karma-chai": "",
    "karma-chrome-launcher": "",
    "karma-cli": "",
    "karma-firefox-launcher": "",
    "karma-ie-launcher": "",
    "karma-jquery": "",
    "karma-mocha": "",
    "karma-opera-launcher": "",
    "karma-safari-launcher": "",
    "karma-sinon": "",
    "mocha": "",
    "sinon": "*"
}

但是当我运行 karma 我得到这个错误

我已经尝试在全球安装 karma-mocha 和 mocha。我尝试在 karma.conf.js

上将 karma-mocha 作为插件

Answer 1

我使用 'tdd' 进行 mocha 配置。应该是 'bdd'.

// Plugin specific config
client: {
  mocha: {
    reporter: 'spec',
    ui: 'bdd'
  }
}

如果设置为 'bdd' 而不是 'tdd'

，则

'describe' 会暴露

Mocha interfaces: Uncaught ReferenceError: `describe` is not defined

Mocha interfaces: Uncaught ReferenceError: `describe` is not defined

mocha.js

karma-runner

karma-mocha
