Question

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

这是一个失败的余烬单元测试，错误是这个问题的标题。

Answer 1

如果您使用的是Ember，请尝试在Ember.run =＆gt;中包装异步调用。 read this

我理解的是，如果您在单元测试中将@set(..,..)设置为@store()并获得此错误，那么您应该使用Ember.run =>

此外，请记住箭头必须是一个胖箭头（我使用->而不是=>犯了一个错误）这是因为javascript范围，如果你感兴趣，请阅读它

解决方案：观察我刚刚添加第2行

 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

确保在此测试中调用done（）回调
