Question

我已经在很多论坛上检查了很多类似的问题。但与我的不完全相似。另外，我不想将登录方法移动到base。

代码：

LoginTest.cs

using test_TestAutomation.PageObjects;
using NUnit.Framework;    

namespace test_TestAutomation.TestClasses
{      
    class LoginTet
    {
       // public IWebDriver driver;

        [Test]
        public void LoginSuccessCheck()
        {    
            LoginPage login = new LoginPage();
            login.LoginSuccess();    
        }
    }
}

Base.cs

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using NUnit.Framework;   

namespace test_TestAutomation.TestClasses
{
    class Base
    {    
        public static IWebDriver driver;       
        [SetUp]
        public void SetUp()
        {
            driver = new ChromeDriver();
            driver.Manage().Window.Maximize();                                    
        }  

        [Test]
        public void OpenURL()
        {
            driver.Navigate().GoToUrl("http://www.example.com");    
        }    

        [TearDown]    
        public void TearDown()
        {
            driver.Close();

        }
    }
}

LoginPage.cs

using OpenQA.Selenium;
using OpenQA.Selenium.Support.PageObjects;
using test_TestAutomation.TestClasses;
namespace test_TestAutomation.PageObjects
{        
    public class LoginPage
    {      
        [FindsBy(How = How.Id, Using = "Email")]
        public IWebElement LoginEmailTxtLocator;

        [FindsBy(How = How.Id, Using = "Password")]
        public IWebElement LoginPasswordTxtLocator;

        [FindsBy(How = How.CssSelector, Using = "#loginForm > div > div > form > div:nth-child(5) > div > input")]
        private IWebElement BtnLogin;    

        public LoginPage()
        {    
            PageFactory.InitElements(Base.driver, this);
        }

        public LoginPage LoginSuccess()
        {               
            LoginEmailTxtLocator.SendKeys("emailtest@gmail.com");
            LoginPasswordTxtLocator.SendKeys("xxxxxxx");
            BtnLogin.Click();
            return this;
        }    
    }
}

例外：

结果讯息： System.ArgumentException：定位器对象的SearchContext不能为null

我建议您将测试OpenURL从Base提取到LoginTest，并仅在Base中进行设置和拆解。然后让LoginTest继承Base。

<强> Base.cs

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using NUnit.Framework;

namespace test_TestAutomation.TestClasses
{
    public class Base
    {
        public static IWebDriver driver;

        [SetUp]
        public void SetUp()
        {
            driver = new ChromeDriver();
            driver.Manage().Window.Maximize();
        }

        [TearDown]
        public void TearDown()
        {
            driver.Close();
        }
    }
}

<强> LoginTest.cs

using test_TestAutomation.PageObjects;
using NUnit.Framework;

namespace test_TestAutomation.TestClasses
{
    class LoginTest : Base
    {
        [Test]
        public void OpenURL()
        {
            driver.Navigate().GoToUrl("http://www.example.com");
        }

        [Test]
        public void LoginSuccessCheck()
        {
            driver.Navigate().GoToUrl("http://www.example.com");
            LoginPage login = new LoginPage();
            login.LoginSuccess();
        }
    }
}

<强> LoginPage.cs

using OpenQA.Selenium;
using OpenQA.Selenium.Support.PageObjects;
using test_TestAutomation.TestClasses;

namespace test_TestAutomation.PageObjects
{
    public class LoginPage
    {
        [FindsBy(How = How.Id, Using = "Email")]
        public IWebElement LoginEmailTxtLocator;

        [FindsBy(How = How.Id, Using = "Password")]
        public IWebElement LoginPasswordTxtLocator;

        [FindsBy(How = How.CssSelector, Using = "#loginForm > div > div > form > div:nth-child(5) > div > input")]
        private IWebElement BtnLogin;

        public LoginPage()
        {
            PageFactory.InitElements(Base.driver, this);
        }

        public LoginPage LoginSuccess()
        {
            LoginEmailTxtLocator.SendKeys("emailtest@gmail.com");
            LoginPasswordTxtLocator.SendKeys("xxxxxxx");
            BtnLogin.Click();
            return this;
        }
    }
}
