BoDi.ObjectContainerException：无法解析接口：OpenQA.Selenium.IWebDriver

Question

我正在使用 C# 创建一个新的 Selenium 框架，因为 PageFactory 已被弃用且不再使用。我正在使用依赖注入，我的代码构建没有错误但是当我运行我的测试时 chrome 浏览器没有打开并且我得到错误：

Message: BoDi.ObjectContainerException : Interface cannot be resolved: 
OpenQA.Selenium.IWebDriver (resolution path: 
UnitTestProject1.Steps.LoginSteps->UnitTestProject1.Page.LoginPage)

我不确定哪里出了问题。我认为与驱动程序有关。感谢您的帮助，谢谢。

基础Class

namespace UnitTestProject1
{
[Binding]    
public class SpecflowBaseTest : TechTalk.SpecFlow.Steps
{
    protected IWebDriver Driver { get; }
    //protected LoginPage LoginPage { get; }

    /*public SpecflowBaseTest()
    {
    }*/

    public SpecflowBaseTest(IWebDriver driver)
    {
        Driver = driver;            
    }

    public void NavigateToURL(string URL)
    {
        Driver.Navigate().GoToUrl(URL);
    }
}
}

Specflow 挂钩

namespace UnitTestProject1
{
public class SpecFlowHooks
{
    private readonly IObjectContainer container;

    public SpecFlowHooks(IObjectContainer container)
    {
        this.container = container;
    }

    [BeforeStep]
    public void CreateWebDriver()
    {
        // Create and configure a concrete instance of IWebDriver
        IWebDriver driver = new ChromeDriver();
        {

        };

        // Make this instance available to all other step definitions
        container.RegisterInstanceAs(driver);
    }

    [AfterStep]
    public void DestroyWebDriver()
    {
        IWebDriver driver = container.Resolve<IWebDriver>();

        driver.Close();
        driver.Dispose();
    }
}
}

登录页面Class

namespace UnitTestProject1.Page
{
public class LoginPage : SpecflowBaseTest
{
    public LoginPage(IWebDriver browser) : base(browser)

    {
        //Driver = browser;
    }

    public void Login(string Username, string Password)
    {
        UsernameField.SendKeys(Username);
        PasswordField.SendKeys(Password);
        LoginButton.Click();
    }

    public void CheckUserIsLoggedIn(string Username)
    {
        AccountUsername.Displayed.ShouldBe(true, Username);
    }

    [FindsBy(How = How.CssSelector, Using = "#LoginUsername")]
    private IWebElement UsernameField { get; set; }

    [FindsBy(How = How.CssSelector, Using = "#LoginPassword")]
    private IWebElement PasswordField { get; set; }

    [FindsBy(How = How.CssSelector, Using = "#login-submit-button")]
    private IWebElement LoginButton { get; set; }

    [FindsBy(How = How.CssSelector, Using = "#div.accountUsrename")]
    private IWebElement AccountUsername { get; set; }

}
}

登录步骤文件

namespace UnitTestProject1.Steps
{
[Binding, Parallelizable]
public class LoginSteps : SpecflowBaseTest
{
    //protected LoginPage LoginPage;
    //protected IWebDriver Driver;
    private LoginPage LoginPage { get; }

    public LoginSteps(LoginPage loginpage, IWebDriver driver) : base(driver)
    {
        //Driver = driver;
        this.LoginPage = new LoginPage(driver);
    }

    [Given(@"I navigate to (.*)")]
    public void GivenINavigateToHttpstesta_Com(string URL)
    {
        NavigateToURL(URL);
    }

    [Given(@"I enter bw_(.*) and (.*)")]
    public void GivenIEnterBw_Valid_UserAnd(string Username, string Password)
    {            
        LoginPage.Login(Username, Password);
    }

    [Then(@"I am logged in as valid_user")]
    public void ThenIAmLoggedInAsBw_Valid_User()
    {
        //LoginPage.
    }
}
}

您缺少 SpecFlowHooks 的 class 名称上方的 [Binding] 属性。 [Binding] 属性是 SpecFlow 在识别步骤定义和 "hooks" 文件时查找的内容。这意味着 SpecFlowHooks class 方法没有被执行，因此 IWebDriver 对象没有在 SpecFlow 的依赖注入框架中注册。
