使用泛型的Selenium Webdriver和Type构造函数-如何做

Question

使用selenium 2 webdriver的PageFactory设计的最佳方法是什么，但是当页面不总是加载预期的页面时，我如何创建新的意外页面?

public class PassengerPage
{
      [FindsBy(How = How.Id, Using "submitId")
      IWebElement submitButton { get; set; }
      private readonly IWebDriver driver;

      public PassengerPage(IWebdriver driver)
      {
          if(!driver.url.Contains"Passengers.aspx")
          {
              throw new NotFoundException("Not the passenger page");
          }
          this.driver = driver;
          PageFactory.InitElements(driver, this);
      }
      public PassengerPage NewPassenger(Passenger p)
      {
           // fill out some forms
           // Example:
           // someInputField.sendKeys(p.Name);
           submitButton.Click(); // Ok, submit clicked, possibility of passenger page
           // not coming back, depending on how many passengers were filled out
           // But what if its not...
           return new PassengerPage(driver);
      }
}

//如果在submitButton.Click()之后返回的页面;就是坚信礼。aspx页面?我不能100%确定，这取决于之前的要求，比如签到，然后说需要多少乘客，但这并没有存储在这个页面。

我可以使用某种类型构造函数吗?

那么我可以这样做吗:

public class PassengerPage
{
      [FindsBy(How = How.Id, Using "submitId")
      IWebElement submitButton { get; set; }
      private readonly IWebDriver driver;
      public PassengerPage(IWebdriver driver)
      {
          if(!driver.url.Contains"Passengers.aspx")
          {
              throw new NotFoundException("Not the passenger page");
          }
          this.driver = driver;
          PageFactory.InitElements(driver, this);
      }
      public Page<T> NewPassenger(Passenger p)
      {
           // fill out some forms
           // Example:
           // someInputField.sendKeys(p.Name);
           submitButton.Click(); // Ok, submit clicked, possibility of passenger page
           // not coming back, depending on how many passengers were filled out
           var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(30));
           wait.Until(d => d.url.Contains("Passenger.aspx") || d => d.url.Contains("Confirmation.aspx");

          if(driver.Url.Contains("Passenger.aspx")
          {
              return Page.Create<PassengerPage>(driver);
          }
          if(driver.Url.Contains("Confirmation.aspx")
          {
             return Page.Create<ConfirmationPage>(driver);
          }
      }
}

在另一门课上我可以使用这样的东西吗?我从来没有像这样使用过泛型考虑使用类似Java Class.forName(name);

// Some kind of Type Constructor
public class Page 
{
       public static T Create<T>(IWebDriver driver) where T : new()
       {
              return new T(driver);
       }
}

我主要担心的是我不能像下面这样在单元测试中链接我的函数:

[Test(Description = "Some description about my unit test")
public void TestAddPassengerAndConfirm()
{
    new LoginPage(driver).Login("username", "password")
                         .NavigateToSearch()
                         .Search( /* input search criteria */ )
                         .SelectSearchResult(Result.First)
                         .AddPassenger(new Passenger()
                                           {
                                               FirstName = "first",
                                               LastName = "last",
                                           })
                         .AddPassenger(new Passenger()
                                           { 
                                              // More properties
                                           })
                         .ConfirmPassengers() // This would be a function on my ConfirmationPage
                                              // That would return the HomePage or something
}

有什么建议我应该怎么做吗?

您将不得不将该方法链拆分为多个语句。在c#中，我会做如下的事情。它不那么漂亮(如果你相信方法链)，也不那么容易，但如果编程很容易，我们就不会得到报酬了。

public void TestAddPassengerAndConfirm()
{
    Page uncertainPage = new LoginPage(driver).Login("username", "password")
                                              .NavigateToSearch()
                                              .Search( /* input search criteria */ )
                                              .SelectSearchResult(Result.First);
    if (uncertainPage is PassengerPage)
    {
        PassengerPage passengerPage = (PassengerPage) uncertainPage;
        uncertainPage = passengerpage.AddPassenger(new Passenger()
                                                       {
                                                           FirstName = "first",
                                                           LastName = "last",
                                                       })
                                     .AddPassenger(new Passenger()
                                                       { 
                                                           // More properties
                                                       });
     }
    if (uncertainPage is ConfirmationPage)
    {
        ConfirmationPage confirmationPage = (ConfirmationPage) uncertainPage;
        confirmationPage.ConfirmPassengers();
    }
}
