错误CS7036没有给出与"SpecflowBaseTest.SpecflowBaseTest(IWebDriver)"的所需形式参数"driver"相对应的参数 [英] Error CS7036 There is no argument given that corresponds to the required formal parameter 'driver' of 'SpecflowBaseTest.SpecflowBaseTest(IWebDriver)'

问题描述

由于不推荐使用PageFactory，因此我正在创建一个新框架.我遇到了错误

I am creating a new framework as PageFactory has been deprecated. I am getting the error

Error CS7036 There is no argument given that corresponds to the required 
formal parameter 'driver' of 
'SpecflowBaseTest.SpecflowBaseTest(IWebDriver)' UnitTestProject1 
D:\Selenium 
Projects\Olympus\UnitTestProject1\UnitTestProject1\Steps\LoginSteps.cs 14 
Active

下面是我的框架的完整代码段.我正在尝试进行依赖项注入，因为PageFactory已弃用，不再使用.

My full code snippet of my framework is below. I am trying the dependency injection because PageFactory is deprecated, not used anymore.

我不确定如何解决此错误.一些帮助表示赞赏.谢谢

I am not sure how to resolve this error. Some help appreciated. Thanks

推荐答案

您实际上应该在这里做三件事.

There are three things you really should do here.

1. 从SpecflowBaseTest中删除LoginPage属性
2. 从LoginSteps调用基类构造函数
3. 将LoginPage属性和初始化代码移至LoginSteps:

1. Remove LoginPage property from SpecflowBaseTest
2. Call the base class constructor from LoginSteps
3. Move the LoginPage property and initialization code into LoginSteps:

[Binding]
public class LoginSteps : SpecflowBaseTest
{
    private LoginPage LoginPage { get; }

    public LoginSteps(IWebDriver driver) : base(driver)
    {
        LoginPage = new LoginPage(driver);
    }
}
