确保此测试中调用了done（）回调

问题描述

it 'computes correctly when on & off have a list at cronRange[4]', ->
    @component.set('cronRanges', [Ember.Object.create({
      on: "* * * 3 3,1,5"
      off: "* * * 3 3,1,5"
    })])
    @component.set('dayOfWeek', 2)
    expect(@component.get('inRange')).to.be.false
    @component.set('dayOfWeek', 5)
    expect(@component.get('inRange')).to.be.true
    @component.set('dayOfWeek', 1)
    expect(@component.get('inRange')).to.be.true
    @component.set('dayOfWeek', 3)
    expect(@component.get('inRange')).to.be.true

这是炭烬单元测试，但由于错误是该问题的标题。

this is an ember unit test that fails with the error that is the is the title of this question.

推荐答案

如果您使用的是Ember，请尝试将异步调用包装在Ember.run =>

If you're using Ember, try wrapping async calls in Ember.run => read this

我了解的是，如果您在单元测试中将 @set（..，..）设置为 @store（） ，并收到此错误，则应使用 Ember.run =>

What I understood is, if you're setting something @set(..,..) to the @store(), in the unit tests, and get this error, then you should use Ember.run =>

此外，请记住箭头成为粗箭头，（我曾经使用-> 而不是 => 犯了这个错误），由于JavaScript的范围，如果您有兴趣，请继续阅读。

Also, remember the arrow has to be a fat arrow, (i made that mistake once of using -> instead of =>)it's because of javascript scope, read up on it if you are interested.

解决方案：请注意，我刚刚添加了第2行

Solution: observe that I just added line # 2

 it 'computes correctly when on & off have a list at cronRange[4]', ->
  Ember.run =>
    @component.set('cronRanges', [Ember.Object.create({
      on: "* * * 3 3,1,5"
      off: "* * * 3 3,1,5"
    })])
    @component.set('dayOfWeek', 2)
    expect(@component.get('inRange')).to.be.false
    @component.set('dayOfWeek', 5)
    expect(@component.get('inRange')).to.be.true
    @component.set('dayOfWeek', 1)
    expect(@component.get('inRange')).to.be.true
    @component.set('dayOfWeek', 3)
    expect(@component.get('inRange')).to.be.true
