Angularjs 单元测试角度ui路由器最大调用堆栈

我是angular ui router的新手，我一直在尝试对基本身份验证进行一些单元测试，在遇到最大调用堆栈错误之前，它工作正常

我已将错误缩小到app.run部分中的$state.go调用。 我去掉这个，测试就开始了。但是它破坏了我的应用程序

我能做些什么来解决这个问题？所以我可以测试这个部分，使它也工作？ 为什么这项工作正常，但会导致测试错误

错误：

RangeError: Maximum call stack size exceeded

代码：

---

超过最大调用堆栈表明正在递归地发生某些事情。我猜您将要启动的状态也未被授权，因此您会被重定向到重新启动，等等

---

您需要使AuthService.IsAuthorized在某个点返回true，以便确定它似乎是ui路由器的错误

这里有一个解决方案

上面的代码将在不破坏浏览器或单元测试的情况下处理该问题。 使用此修复程序时请小心。

使用$state.gomain，{}，{notify:false}；用于通知$stateChangeStart事件

先生，您说得对，我在$state前面放了一个控制台日志。去获取当前状态，当前状态总是空的！console.logJSON.stringify$state；日志：{params:{}，当前：{name:}，url:^，视图：null，抽象：true}，$current:{self:{name:，url:^，视图：null，抽象：true}，解析：{}，url:{segments:[]，params:{}，sourcePath:，sourceSearch:，regexp:{}，前缀：}，可导航：null，参数：{}，视图：{}，ownParams:[]，路径：]，包括：{true}，局部：{resolve:null，全局：{states:}，transition“嗯，但是如果有一个循环，那么为什么我仍然可以实际使用该站点并转换到其他状态，而不让浏览器不断输出日志条目呢？因为在真实的网站上，您的auth服务工作正常，但在测试中，您伪造authservice以始终返回false:spyOnAuthService，isAuthorized.andCallFakefunction状态{return false；}
