org.testng.testngexception：无法实例化类

Question

当我试图运行我的脚本时，我收到以下错误

package EDRTermsPackge;

import org.testng.annotations.Test;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.BeforeMethod;

public class ContactInformationTesting {

 //For use of IE only; Please enable for IE Browser
 WebDriver driver = new InternetExplorerDriver();

 @BeforeMethod
 public void beforeMethod() {
  //Using or Launching Internet Explorer
  String exePath = "\\Users\\jj85274\\Desktop\\IEDriverServer.exe";

  //For use of IE only; Please enable for IE Browser
  System.setProperty("webdriver.ie.driver", exePath);
 }

 @Test
 public void OpenPage_Login() {
  driver.get("http://cp-qa.harriscomputer.com/");
 }
}

Answer 1

您应该先将路径设置为driver然后实例化IEDriver,您不能在System.SetProperty（“webdriver.ie.driver”,exePath）之前使用new InternetExplorerDriver（）；

在您的示例中，可以执行如下操作（不需要@BeforeMethod来执行简单的属性设置）：

public class ContactInformationTesting {

  //Using or Launching Internet Explorer
  String exePath = "\\Users\\jj85274\\Desktop\\IEDriverServer.exe";

  //For use of IE only; Please enable for IE Browser
  System.setProperty("webdriver.ie.driver", exePath);

  //For use of IE only; Please enable for IE Browser
  WebDriver driver = new InternetExplorerDriver();

 @Test
 public void OpenPage_Login() {
  driver.get("http://cp-qa.harriscomputer.com/");
 }
