Question

我正在尝试使用与Xamarin集成的SpecFlow。在测试期间，我能够安装应用程序（* .apk）并çanch它进入登录页面，但后来我得到错误：

BoDi.ObjectContainerException was unhandled by user code
HResult=-2146233088
Message=Primitive types or structs cannot be resolved: Xamarin.UITest.Platform (resolution path: VVM_SpecFlow.LoginApplicationSteps)

  InnerException:  a

我相信在specflow读取要素文件后会发生这种情况。

有人可以帮我吗？

Answer 1

您的LoginApplicationSteps有一个带参数Xamarin.UITest.Platform的构造函数。这是一种让你烦恼的原始类型 SpecFlow有一个集成的DI框架，用于解析绑定类。它使用构造函数注入。在您的情况下，它正在搜索平台枚举的注册，这不起作用。解决方案是将枚举包装在一个类中并在BeforeScenario挂钩中注册它（参见链接文档页面上的高级选项）。

DI-框架的文档（在SpecFlow中称为上下文注入）在这里：http://specflow.org/documentation/Context-Injection/

如果有人在步骤类之间使用BoDi作为容器，这是我解决原始类型的解决方法：

var test = (string)objectContainer.Resolve<object>("testString");

错误运行specflow Xamarin测试时无法解析原始类型或结构
