Java safardriver在@Aftermethod中调用driver.close（）之前自动关闭

我在Windows7上的safari浏览器版本5.1.7中运行以下测试脚本

运行@test方法后，我正在@aftermethod中调用driver.quit（）。但是safari浏览器在到达@aftermethod并抛出java.lang.NullPointerException错误之前关闭。由于此新的safari浏览器实例在浏览器关闭后未打开。如何解决此问题？如何覆盖safari关闭？下面是执行日志

  public class Test{
            WebDriver driver;
        @BeforeMethod
        public void init()
        {
            driver = invokeSafariDriver();
        }

    public static WebDriver invokeSafariDriver() throws InterruptedException
        {
            //logger.log(LogStatus.INFO, "Launching Chrome driver");
            System.out.println("Launching Safari driver");

            System.setProperty("webdriver.safari.noinstall", "true");
            WebDriver driver = new SafariDriver();
            driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
            driver.manage().window().maximize();
            Thread.sleep(2000);
            return driver;
        }

        @Test
        public void launch
        {
            driver.get("www.google.com");
        }


      @AfterMethod(alwaysRun=true)
        public void closeBrowser()
        {
            try{
                System.out.println("Closing the browser");
                logger.log(LogStatus.INFO, "Closing the Browser");
                driver.quit();
            }
            catch(Exception e){
                driver.close();

            }

        }

您应该先初始化WebDriver实例，然后再使用它

WebDriver driver;

@BeforeMethod
public void init()
{
    driver = new SafariDriver();
}

@Test
public void launch
{
    driver.get("www.google.com");
}

@AfterMethod
public void tearDown()
{
    driver.quit();
}

---

您应该在

init（）

method之外定义Webdriver，以便在其他方法中也可以访问它

    WebDriver driver;

    @BeforeMethod
    public void init()
    {
        driver = new SafariDriver();
    }

    @Test
    public void launch
    {
        driver.get("www.google.com");
    }

    @AfterMethod
    public void tearDown()
    {
        driver.quit();
    }

试试这个

public class Test{
        public WebDriver driver;

        @BeforeMethod
        public void init()
        {
            invokeSafariDriver();
        }

    public static void invokeSafariDriver() throws InterruptedException
        {
            //logger.log(LogStatus.INFO, "Launching Chrome driver");
            System.out.println("Launching Safari driver");

            System.setProperty("webdriver.safari.noinstall", "true");
            driver = new SafariDriver();
            driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
            driver.manage().window().maximize();
            Thread.sleep(2000);
            //return driver;
        }

        @Test
        public void launch()
        {
            driver.get("www.google.com");
        }


      @AfterMethod(alwaysRun=true)
        public void closeBrowser()
        {
            try{
                System.out.println("Closing the browser");
                logger.log(LogStatus.INFO, "Closing the Browser");
                driver.quit();
            }
            catch(Exception e){
                driver.close();

            }

        }

测试代码在哪里？在测试方法中，我只是打开浏览器，在beforemethod中，我实例化了safaridriver，比如WebDriver driver=new safaridriver（）；请在问题中添加相关代码。代码更新：）如何

launch（）

和

tearDown（）

甚至知道

driver

是什么？由于Safaridriver自动关闭浏览器，Aftermethod中出现异常。您可以在safaridriver关闭连接并关闭浏览器的位置查看我的日志。我面临的主要问题是“Safari浏览器在driver.quit（）调用之前自动关闭”为什么要在

invokeSafariver（）方法中再次定义
WebDriver
，删除WebDriver请尝试使用下面的代码
System.setProperty（“WebDriver.Safari.noinstall”，“true”）；driver=新的SafariDriver（）
使用以下命令更新
inti（）
方法
public void init（）{driver=invokesafridriver（）；}
和
public static void invokesafridriver（）抛出interruptedeexception{//logger.log（LogStatus.INFO，“启动Chrome驱动程序”）；System.out.println(“启动Safari驱动程序”）；System.setProperty（“webdriver.Safari.noinstall”，“true”）；driver=new SafariDriver（）；……Thread.sleep（2000）；//return driver；}
