unit-testing - How to write jasmine test to check update

Question

I'm trying to write jasmine test to check is view changing time or not

it 'ticks the time', ->
  @time = parseInt($('#timer h1').text())
  setTimeout (->
    @after = parseInt($('#timer h1').text())
    expect(@time).toBeLessThan(@after)
  ), 1000

The problem is that when time of setTimeout is up the jasmine is already finished his job, no html code on page related to this test at that moment.

Jasmine 已经为此类任务提供了解决方案：

it 'ticks the time', ->
  runs ->
    @time = parseInt($('#timer h1').text())
  waits(1000)
  runs ->
    @after = parseInt($('#timer h1').text())
    expect(@time).toBeGreaterThan(@after)
