当我尝试使用 mocha 执行我的 react 测试时,出现以下错误:

/Users/niklaskiefer/Github/adal-fronted/test/CasesSpec.js:49
(0, _chai.describe)('Cases', function () {
^

TypeError: (0 , _chai.describe) is not a function

测试位于 test/CasesSpec:

import * as React from 'react'
import ReactDOM from 'react-dom'
import TestUtils from 'react-addons-test-utils'
import CaseActions from 'actions/CaseActions'
import CaseStore from 'stores/CaseStore'
import FilterStore from 'stores/FilterStore'
import { expect, it, before, describe } from 'chai'
import Immutable from 'immutable'
import Globals from 'config/globals'
import moment from 'moment'

var TestCases = require('./config/TestCases.js')

describe('Cases', function () {
before(function (done) {
this.timeout(1000)

// fetch all data here because
...

我使用以下命令通过“npm test”执行测试

NODE_PATH=./app mocha --compilers js:babel-core/register,css:test/config/css-compiler.js --recursive --require test/config/setup.js

css-compiler.js:

function donothing () {
return null
}

require.extensions['.css'] = donothing
require.extensions['.less'] = donothing
require.extensions['.scss'] = donothing

设置.js:

// this handles setup of the fake DOM when the tests are
// run in Node

import jsdom from 'jsdom'

var FAKE_DOM_HTML = `
<html>
<body>
</body>
</html>
`

function setupFakeDOM () {
if (typeof document !== 'undefined') {
// if the fake DOM has already been set up, or
// if running in a real browser, do nothing
return
}

// setup the fake DOM environment.
//
// Note that we use the synchronous jsdom.jsdom() API
// instead of jsdom.env() because the 'document' and 'window'
// objects must be available when React is require()-d for
// the first time.
//
// If you want to do any async setup in your tests, use
// the before() and beforeEach() hooks.
global.document = jsdom.jsdom(FAKE_DOM_HTML)
global.window = document.defaultView
global.navigator = window.navigator
}

setupFakeDOM()

几周前它工作正常,我们唯一改变的是我们使用 standardJS 作为新的代码风格。我们还将 babel-core 从 6.10.4 更新到 6.11.4。我尝试了这个解决方案:Babel/Mocha: Mocha installed globally but describe() is not defined并删除“--require”。但这只会导致没有执行任何测试

最佳答案

itbeforedescribe 是 Mocha 自动添加到全局空间的符号。因此,无需导入任何内容即可在测试中使用它们。

chai 当然与他们无关。所以:

import { expect } from 'chai'
