我如何才能成功地传递此代码？JavaWebDriverTestNG

我想把这段代码传递给我的其他类，这样我就不必一直粘贴它了

这是包含以下代码的类：

package utility;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

public class BrowserType {
    public static WebDriver driver;

    @Parameters("browser")
    @Test
    public static void CallBrowser(String browser) {

        if(browser.equalsIgnoreCase("firefox")) {

              driver = new FirefoxDriver();

          // If browser is IE, then do this   

          }else if (browser.equalsIgnoreCase("chrome")) { 

              // Here I am setting up the path for my IEDriver

              {System.setProperty("webdriver.chrome.driver","C:/Users/elsid/Desktop/Eclipse/Selenium/chromedriver.exe");}
               driver = new ChromeDriver();

              driver.get(Constant.URL);

          } 

    }
}

public WebDriver driver;



@BeforeMethod
@Parameters("browser")
public void SetUp(String browser) {

     BrowserType.CallBrowser(browser);
      } 

我想将

CallBrowser

传递到

SetUp

，如下所示：

package automationFramework;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

import utility.Constant;
import appModule.SignIn_Action;

public class SignIn {

    public WebDriver driver;



@BeforeMethod
@Parameters("browser")
public void SetUp(String browser) {

     if(browser.equalsIgnoreCase("firefox")) {

          driver = new FirefoxDriver();

      // If browser is Chrome, then do this   

      }else if (browser.equalsIgnoreCase("chrome")) { 

          { System.setProperty("webdriver.chrome.driver","C:/Users/elsid/Desktop/Eclipse/Selenium/chromedriver.exe");}
          driver = new ChromeDriver();

          { driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);}
          {driver.manage().window().maximize();}
           driver.get(Constant.URL);
      }
      } 

@Test
public  void signIn() {

    SignIn_Action.Execute(driver, Constant.DevStudentUsername, Constant.DevStudentPassword);      
 }  

@AfterMethod
public void Teardown() {
    driver.quit();

} 

  }

我尝试只调用静态类，但是

@BeforeMethod

抛出了一个配置错误，我确信我只是在传递驱动程序和参数时出错了

有人能解释一下我需要对这两个类进行哪些更改才能使其正常工作吗

以下是错误：

这就是我试图调用代码的方式：

package utility;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.Parameters;
import org.testng.annotations.Test;

public class BrowserType {
    public static WebDriver driver;

    @Parameters("browser")
    @Test
    public static void CallBrowser(String browser) {

        if(browser.equalsIgnoreCase("firefox")) {

              driver = new FirefoxDriver();

          // If browser is IE, then do this   

          }else if (browser.equalsIgnoreCase("chrome")) { 

              // Here I am setting up the path for my IEDriver

              {System.setProperty("webdriver.chrome.driver","C:/Users/elsid/Desktop/Eclipse/Selenium/chromedriver.exe");}
               driver = new ChromeDriver();

              driver.get(Constant.URL);

          } 

    }
}

public WebDriver driver;



@BeforeMethod
@Parameters("browser")
public void SetUp(String browser) {

     BrowserType.CallBrowser(browser);
      }

您的问题是在调用teardown时驱动程序未初始化。您需要确保它在所有情况下都已初始化。我将使用调试器检查您的代码，并确保当您点击setup和teardown方法时，驱动程序实际上是在setup时初始化的，并且在拆卸时存在。当事情运行时，您还有两个驱动程序在场。一个是在代码的第一部分声明的静态驱动程序，然后在实际测试中找到另一个非静态驱动程序。我会解决这个问题，因为它可能会引起问题

解决问题的最简单方法是确保在安装过程中始终初始化驱动程序，即使字符串与任一选项都不匹配

public void SetUp(String browser) {

     if(browser.equalsIgnoreCase("firefox")) {

          driver = new FirefoxDriver();

      // If browser is Chrome, then do this   

      }else { 

          System.setProperty("webdriver.chrome.driver","C:/Users/elsid/Desktop/Eclipse/Selenium/chromedriver.exe");
          driver = new ChromeDriver();

          { driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);}
          {driver.manage().window().maximize();}
           driver.get(Constant.URL);
      }
}

你能把这个错误包括进来吗？更新了这个错误，它抛出了一个空指针，因为我可能没有正确地传递参数和驱动程序。是的，有一些问题，但它确实令人困惑，因为我没有太多java知识。通过删除静态驱动程序并将其更改为webdriver driver=newfirefoxdriver（），我使部分功能正常工作；它在“设置”中正确运行，但现在我不知道如何将该驱动程序传递给类的其他部分，如test&aftermethod。@Elsid更新了答案您能提供一个示例吗？Thanks@Elsid这里是一个粗略的例子，有更好的方法来实现它Hanks Mo，这就是我现在所拥有的，我试图通过将代码移动到另一个类并调用它来替换所有代码。
