java - 配置失败: @AfterClass tear

Question

我正在使用 selenium 2.39 和 Testng火狐浏览器版本26

下面是代码

   package Examples;

   import java.util.concurrent.TimeUnit;

   import org.junit.BeforeClass;
   import org.openqa.selenium.By;
   import org.openqa.selenium.WebDriver;
   import org.openqa.selenium.firefox.FirefoxDriver;
   import org.testng.annotations.AfterClass;
   import org.testng.annotations.DataProvider;
   import org.testng.annotations.Test;

   public class Example2 {
   public static WebDriver driver;
   //String ddd;
   //    public Example2() {
   //       super();
    //    }

@BeforeClass
public void beforeClass()
{
driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(60000, TimeUnit.MILLISECONDS);
}

@Test(dataProvider="Mail Information")
public void mailSend(String to,String subject,String body) throws Exception

{

    driver.get("https://www.gmail.com");
    driver.findElement(By.id("Email")).sendKeys("xyzy@gmail.com");
    driver.findElement(By.id("Passwd")).sendKeys("*********");
    driver.findElement(By.id("signIn")).click();

    driver.findElement(By.cssSelector("div[class='T-I J-J5-Ji T-I-KE L3']")).click();
    driver.findElement(By.className("vO")).sendKeys(to);    
    driver.findElement(By.className("aoT")).sendKeys(subject);

    driver.findElement(By.cssSelector(".editable")).click();
    driver.switchTo().frame(driver.findElement(By.xpath("//iframe[contains(@tabindex,'1') and contains(@frameborder,'0')]"))); 
    driver.findElement(By.xpath("//body[@role='textbox']")).sendKeys(body);    
    driver.switchTo().defaultContent();       
    driver.findElement(By.cssSelector("div[class='T-I J-J5-Ji aoO T-I-atl L3']")).click();

    driver.navigate().refresh();
}

@DataProvider (name = "Mail Information")
public Object[][] mailSendProvider() 
{
    return new Object[][]

            {

            {"xyzy@gmail.com","This is a Test Mail","hello"},
            };

}

@AfterClass
public void tear()
{
    driver.quit();
   }
}

无法理解测试库的问题或 Testng 设置的问题

当 iam 使用 TestNG 运行时，我收到以下错误。

有人可以帮我吗

Answer 1

注释“BeforeClass”是从 Junit 导入的，并且“AfterClass”是从 TestNg 导入的。

两者都是不同的 API，错误是由于引用“AfterClass”而没有从 TestNg 定义“BeforeClass”造成的。

请添加以下内容

import org.testng.annotations.BeforeClass; 

并删除以下内容

import org.junit.BeforeClass;

希望这有帮助
