Update: 我设法进一步缩小问题范围,并通过更新包含一些无效ascii字符的 httpBackend.when 请求来修复 Unexpected request 错误 .
我已经附加了一个Plunker当前代码块 .
但是我仍然难以有效地测试触发成功和错误方法操作 . 我还需要增加检查消息广播的期望 .
为了测试上面提到的场景,我设计了一个我已经包含在Plunker中的hack,但我相信应该有更好的方法来测试这些场景 .
任何有关如何克服此问题并测试响应消息状态的线索将非常感激 .
Problem
我为我的测试设置了$ httpBackend的预期值/响应,但是当我运行$ httpBackend.flush()时,它无法指示下面提到的错误 .
Error message indicated
Error: Unexpected request: GET https://192.168.1.10:3334/res?t1=CHECK&t2='?'&req={"_msgType":"Login_msg","UserName":"e@e.com","Password":"123"}
我确实找到了一些讨论这个问题域的有用链接,它们确实帮助我缩小了问题范围 . 但我似乎还无法弄清楚这个单元测试失败的具体原因 .

我也尝试了moving the flush() call around并在测试中发出$ http请求时尝试了calling $apply or $digest,如此处所示 .

我知道,这个问题很老,但也许有人在寻找,这可能会有所帮助 .
像这样修改你的beforeEach函数:
这将解决此错误 .
