Question

好的，在after函数console.log "enter after function"和console.log "exit"中执行，但console.log "WHYYYY"不执行。我无法弄清楚为什么。为了记录，console.log 'insert'确实执行。我在我的一个测试中对mongo进行了类似的调用，所以调用mongo应该可行。

此问题的任何线索或如何解决？

                        console.log "remove?"
                        null
                        return

                db.collection 'tokens', (error, tokensColl) =>

                        return
                return
            console.log "exit after"

Mongo没有足够的时间连接，

尝试在after函数中使用完成回调：

after (done) ->
  console.log "WHYYYY"
  mongo.open (error, db) =>
     ...
     done()
  console.log "exit after"
})

使用after来清理mocha，mongo的问题
