Question

我正在用C＃开发一个硒框架。使用工厂设计实例化页面类以隐藏实例化逻辑，我希望能够使用实例化该类。 var myPageClass = HelperSelenium.Instance(MyPageClass)代替var myPageClass = MyPageClass.Instance(driver)

我尝试在HelperSelenium类中创建泛型函数，但是我还不能完全理解泛型的工作原理。

PageObject类示例（注意，我使用Instance方法实例化该类

public class HomePage : BasePage
{       
    private HomePage(IWebDriver driver, CountryEnum enum) : base(driver) { }

    private static HomePage homePage { get; set; }

    public static HomePage Instance(IWebDriver driver, CountryEnum enum)
    {
        switch (enum)
        {
             case CountryEnum.Sweden:
                 HomePage = new HomePage_SWE(driver);
                 break;
             case CountryEnum.Germany:
                 HomePage = new HomePage_GER(driver);
                 break;
             case CountryEnum.Italy:
                 HomePage = new HomePage_ITA(driver);
                 break;
             default:
                 HomePage = new HomePage_UK(driver);
                 break;
        }

        return homePage;
    }

...
}

public T InstancePage<T>() where T : BasePage
{
    return (T).Instance(WebDriver, CountryEnum.Sweden);
}

最后我使用以下方法解决了

compose

我很确定可以通过使用PageObject.PageFactory

来改善它
