Question

我正在尝试使用扩展区报告构建selenium，但我无法使用save screenshot功能，因为我无法在ITestListener类中引用WebDriver对象。以下是我的示例代码：

Test Runner.java：

@Listeners({com.peterwkc.Listener.TestListener.class})
public class ChromeTestManager {

    private WebDriverManager webDriverManager = new WebDriverManager();
    private WebDriver driver;

    private LoginPages loginPages;
    private AdminPages adminPages;

    @BeforeClass
    //@Parameters({"browser"})
    public void setupTest(/*String browser*/) throws MalformedURLException {
        System.out.println("BeforeMethod is started. " + Thread.currentThread().getId());
        // Set & Get ThreadLocal Driver with Browser

        webDriverManager.createDriver("chrome");
        driver = webDriverManager.getDriver();

        // Pages Object Initialization
        loginPages = PageFactory.initElements(driver, LoginPages.class);
        logoutPages = PageFactory.initElements(driver, LogoutPages.class);
        adminPages = PageFactory.initElements(driver, AdminPages.class);
    }

    @DataProvider(name = "loginCredentials")
    public static Object[][] getLoginCredentials() {
        return new Object [][] {{ "Admin123", "admin123"  }, {"testUser", "test"}, {"test", "test"}};
    }

    @Test(groups= {"Login"}, description="Invalid Login", priority = 0, dataProvider = "loginCredentials", invocationCount = 3) 
    public void login_invalid(String username, String password) {
        loginPages.login_invalid(driver, username, password);
    }
}

TestListener.java 公共类TestListener实现ITestListener {

    //Extent Report Declarations
    private static ExtentReports extent = ExtentManager.createInstance();
    private static ThreadLocal<ExtentTest> test = new ThreadLocal<>();

    public TestListener() {
    }

@Override
    public synchronized void onTestFailure(ITestResult result) {
        System.out.println((result.getMethod().getMethodName() + " failed!"));
        test.get().fail("Exception Error : \n" + result.getThrowable());

        /*String feature = getClass().getName();
        String screenShot;
        try {
            screenShot = CaptureScreenshot.captureScreen(driver, CaptureScreenshot.generateFileName(feature));
            test.get().addScreenCaptureFromPath(screenShot);
            test.get().log(Status.FAIL, screenShot);
        } catch (IOException ex) {    
            LogManager.logger.log(Level.INFO, "Exception: " + ex.getMessage());
        }*/

    }
}

问题：

如何将WebDriver对象从TestRunner.java传递给TestListener 类
如何在范围报告3中保存屏幕截图？
我的代码有什么问题吗？

请提前帮助，谢谢！

首先不要在@BeforeClass中实例化您的webDriver，因为只有在课前注释时才会调用它，尝试使用interface ITestListener并使用beforeInvocation实现进行初始化WebDriver。

其次，你不能一次调用所有PageObjects的PageFactory，你怎么认为所有3个页面一次初始化，这应该在每个页面对象的构造函数中实现，当你初始化你的页面对象时（新的Login）元素也被初始化，所以这不行：

    // Pages Object Initialization
    loginPages = PageFactory.initElements(driver, LoginPages.class);
    logoutPages = PageFactory.initElements(driver, LogoutPages.class);
    adminPages = PageFactory.initElements(driver, AdminPages.class);

第三，我没有看到ExtentReport测试的初始化。它应该看起来像这样：

ExtentTest extentTest = ExtentTestManager.startTest(method.getName(), "");

以下是我调用屏幕截图实现的代码示例部分，我正在调用afterInvocation，因为我使用的是并发驱动程序初始化，所以它必须来自这里，也可以通过onTestFailure实施来实现：

       public synchronized void afterInvocation(IInvokedMethod method, ITestResult testResult){
        if (method.isTestMethod() && testResult.getStatus()==2) {

                File scrFile = (dataMethod.getAndroidDriver()).getScreenshotAs(OutputType.FILE);
                String dest = System.getProperty("user.dir") + "/resources/screenshots/" + dataMethod.getDriver().getSessionId() + ".png";

                File destination = new File(dest);
                try {
                    FileUtils.copyFile(scrFile, destination);
                    dataMethod.setScreenshotPath(destination.getAbsolutePath());
                } catch (IOException e) {
                    e.printStackTrace();
                }
                System.err.println("Path:" + dataMethod.getScreenshotPath());

        }

你必须更多地考虑结构，

希望这会有所帮助......

以下是执行此操作的步骤：

1：将WebDriver对象传递给侦听器类

首先在ChromeTestManager类中或您可以在其处调用的其他任何位置创建以下方法，这里假定它存在于ChromeTestManager类中：

public static ITestContext setContext(ITestContext iTestContext, WebDriver driver) {
        iTestContext.setAttribute("driver", driver);

        return iTestContext;
    }

它将驱动程序对象设置为TestContext。

现在将您的@BeforeClass setUp方法更改为接受参数ITestContext，下面是代码：

public class ChromeTestManager {

        private WebDriverManager webDriverManager = new WebDriverManager();
        private WebDriver driver;

        private LoginPages loginPages;
        private AdminPages adminPages;

        private static ITestContext context;  // creating a ITestContext variable

        @BeforeClass
        //@Parameters({"browser"})
        public void setupTest(ITestContext iTestContext) throws MalformedURLException {
            System.out.println("BeforeMethod is started. " + Thread.currentThread().getId());
            // Set & Get ThreadLocal Driver with Browser

            webDriverManager.createDriver("chrome");
            driver = webDriverManager.getDriver(); 

            this.context = setContext(iTestContext, driver);  // setting the driver into context

            // Pages Object Initialization
            loginPages = PageFactory.initElements(driver, LoginPages.class);
            logoutPages = PageFactory.initElements(driver, LogoutPages.class);
            adminPages = PageFactory.initElements(driver, AdminPages.class);
        }

运行此命令时，它将平稳运行并且不会产生错误（如果您认为我将如何传递ITestcontext上下文，则在内部进行处理）

现在，驱动程序已作为对象添加到ITestcontext中；

现在在侦听器中访问驱动程序：

@Override
    public synchronized void onTestFailure(ITestResult result) {
        WebDriver driver = (WebDriver) result.getTestContext().getAttribute("driver");  // here we are accessing the driver object that we added in Test class  

}

2。在范围报告3中保存ScreenShot（我在Maven中使用依赖项3.1.5）

@Override
    public synchronized void onTestFailure(ITestResult result) {
        System.out.println("!!!!!!!!!!!!!!!!!!!! Test Failed !!!!!!!!!!!!!!!!!!!!");

        WebDriver driver = (WebDriver) result.getTestContext().getAttribute("driver"); // accessing driver here
        String feature = getClass().getName();
        String screenShot;
        try {
            screenShot = CaptureScreenshot.captureScreen(driver, CaptureScreenshot.generateFileName(feature));
            test.addScreenCaptureFromPath(screenShotPath);  // I am assuming that the "screenShot" is fully qualified path with extension e.g "C:\Users\12345\Desktop\sfgfdh.PNG"
        } catch (IOException ex) {    
            LogManager.logger.log(Level.INFO, "Exception: " + ex.getMessage());
        }

    }

3。您的代码有什么问题吗？

否

您只需要在Listener类中使用驱动程序，并在扩展报告中添加屏幕截图时，确保屏幕快照的路径正确并且是带有扩展名的完全限定路径。

如果您遇到此问题，请告诉我。
