我在 Windows 7 上的 Safari 浏览器 5.1.7 版中运行测试脚本。

运行@test 方法后，我在@aftermethod 中调用driver.quit()。但是 safari 浏览器在到达 @aftermethod 并抛出java.lang.NullPointerException错误之前就关闭了。由于这个新的 Safari 浏览器实例在浏览器关闭后没有打开。如何解决这个问题？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();

            }

        }

您应该在 mehtod 之外定义 Webdriver，init()以便它也可以在其他方法中访问。

    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();
}

尝试这个，

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();

            }

        }
