NUnit Specflow如何为所有测试共享一个类实例

有几种方法可以做到这一点。此页面涵盖了大多数

我个人可能要做的是定义一个

SeleniumContext

首先创建用于保存硒驱动程序实例的类

public class SeleniumContext{     public SeleniumContext()     {          //create the selenium context          WebDriver = new ...create the flavour of web driver you want     }     public IWebDriver WebDriver{get; private set;} }

然后将IOC设置为每次返回相同的实例

[Binding]public class BeforeAllTests{    private readonly IObjectContainer objectContainer;    private static SeleniumContext seleniumContext ;    public BeforeAllTests(IObjectContainer container)    {        this.objectContainer = container;    }    [BeforeTestRun]    public static void RunBeforeAllTests()    {        seleniumContext = new SeleniumContext();     }    [BeforeScenario]    public void RunBeforeScenario()    {         objectContainer.RegisterInstanceAs<SeleniumContext>(seleniumContext );    }}

然后确保您的步骤类始终在其构造函数中要求上下文（您需要在每个步骤类中都执行此操作）

[Bindings]public class MySteps{    private SeleniumContext seleniumContext;    public MyClass(SeleniumContext seleniumContext)    {         //save the context so you can use it in your tests         this.seleniumContext = seleniumContext;    }    //then just use the seleniumContext.WebDriver in your tests}

或者，如果您已经将实例存储在功能上下文中，则可以使用

BeforeFeature

[Binding]public class BeforeAllTests{    private static WebDriver webDriver;    [BeforeTestRun]    public static void RunBeforeAllTests()    {        webDriver = new WebDriver();     }    [BeforeFeature]    public static void RunBeforeFeature()    {        FeatureContext["WebDriver"] = webDriver;     }}
