Specflow - 无法在特征文件之间共享步骤
Specflow - Unable to share step between feature files
我是刚刚入门的Specflow新手，希望有人能帮助我？这可能都是我自己对它应该如何工作的误解，但希望有人能帮助我进步。
所以！我有一个正在处理的测试项目，它包含 2 个功能文件和 2 个步骤 class 文件（以及使用 POM 的页面文件）。
1.) ServiceSchedules.feature
2.) ServiceSchedulesSteps.cs
3.) Login.feature
4.) LoginPageSteps.cs
两个功能文件共享一个步骤，'And the browser is closed'，即在每个场景结束时关闭浏览器。这适用于 Login.feature 文件中的场景测试，但不适用于另一个功能文件 ServiceSchedules.feature 中的场景测试，该文件使用 'Driver.Dispose' 在这一步失败。它returns下面的错误；
System.NullReferenceException : Object reference not set to an
instance of an object.
我预计该步骤可以跨功能文件共享？ （也许不是我想要的方式？）
附带说明一下，我知道这可能不是最佳实践，因为我知道您可以使用挂钩，但是当我尝试使用 AfterScenario Hook 尝试关闭浏览器时，我 运行 遇到了另一个问题每次测试。它返回另一个错误（使用与下面相同的代码），当 运行 来自 ServiceSchedules.feature 文件的相同场景测试时；
System.ArgumentException : The SearchContext of the locator object
cannot be null Parameter name: locator
但是回到我当前的问题——这是我的文件；

希望我已经付出了足够的努力继续 - 其他一切正常，只是无法理解为什么 LoginPageSteps.cs 中的 'And the browser is closed' 不会与 scenario/test 中的 scenario/test 共享ServiceSchedules.feature 文件。我在想这可能与方式有关，我首先在哪里初始化驱动程序？不确定我该怎么做。
我确实发现我能够在 ServiceSchedules.feature 和 ServiceSchedulesSteps.cs 文件中创建一个新步骤 'And the browser closes'，并且工作正常，但这当然意味着我有两个步骤它们是一样的，它们真的应该从一个地方和一个文件共享——这就是我认为一切都应该有效的方式！
非常感谢对此提供的任何帮助 - 我对此表示歉意，这是我错过或不理解的明显而愚蠢的事情 - 我正在学习并且对编码相对较新:)
干杯
你的情况的关键时刻是当线程从 ServiceScheduleLoginPageContent 场景执行 And the browser is closed 时。在那种情况下，线程将进入 step 方法（定义在 LoginPageSteps class 内），并且在您尝试调用 Driver.Dispose(); 的那一刻，您会得到错误。这是因为您使用了未初始化的 DRIVER 变量。它永远不会被初始化，因为您的执行过程从 ServiceSchedulesSteps class 开始。您已初始化 Driver 变量，但在 class ServiceSchedulesSteps 中。
我想说的是 [AfterScenario] 可能也是导致单元化变量的原因。
发生这种情况是因为您的步骤 And the browser is closed 在 2 个不同的 .feature 文件中具有相同的语法。当您在不同的 .feature 文件中执行相同的步骤时，specFlow 会识别出在您的项目中已经存在为您的步骤定义的步骤方法（这是因为您为步骤 classes 设置的 [Binding] 属性）。
每个人都会推荐您阅读规范流的上下文注入主题。它允许在不同的 step.cs 文件之间共享数据。但是，如果您的共享参数随着更多场景或功能而增加，您应该考虑如何处理它。您只需 google 它，您就会在文档或某些博客中找到它。
您也可以坚持简单的解决方案，重命名 And the browser is closed 步骤之一并生成新方法，这样您就有了 2 个步骤方法，将一个特征文件中的所有步骤集中在一个 step.cs文件并避免此类问题。现在，请考虑您的 scenarios/features 可能会发生怎样的变化，但不要太在意，您会随着时间的推移处理它。但是上下文注入绝对值得一试。
