Java 当我的测试失败时，在chrome浏览器关闭之前（@After），如何截屏chrome浏览器

我已经运行了这段代码，在chrome浏览器关闭（@after）后截图 如果我把CloseBrowser（）注释掉；截图被捕获，但chromebrowser保持打开状态。 我想截图捕捉失败的测试，然后关闭浏览器

总之 屏幕截图当前在浏览器关闭后捕获，它只是一个空白的.png 我希望在浏览器关闭前测试失败时捕获屏幕截图

谢谢

public class TestClass extends classHelper//has BrowserSetup(); and CloseBrowser(); {

 @Rule
 public ScreenshotTestRule my = new ScreenshotTestRule(); 

 @Before
 public void BeforeTest()
 {
      BrowserSetup();// launches chromedriver browser
 }

 @Test
 public void ViewAssetPage() 
 {
     //My test code here//And want to take screenshot on failure
 }

 @After
 public void AfterTest() throws InterruptedException
 {
      CloseBrowser();//closes the browser after test passes or fails
 }
}

class ScreenshotTestRule implements MethodRule {
    public Statement apply(final Statement statement, final FrameworkMethod frameworkMethod, final Object o) {
        return new Statement() {
            @Override
            public void evaluate() throws Throwable {
                try {
                    statement.evaluate();
                } catch (Throwable t) {
                    captureScreenshot(frameworkMethod.getName());
                    throw t; // rethrow to allow the failure to be reported to JUnit
                }
            }
            public void captureScreenshot(String fileName) {
                try {
                    new File("target/surefire-reports/").mkdirs(); // Insure directory is there
                    FileOutputStream out = new FileOutputStream("target/surefire-reports/screenshot-" + fileName + ".png");
                    out.write(((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES));
                    out.close();
                } catch (Exception e) {
                    // No need to crash the tests if the screenshot fails
                }
            }
        };
    }
}

您可以实现TestNG侦听器，以便在测试之前或之后执行代码 或者测试失败或成功等

如下面所示实现它，并将您的屏幕截图放在我显示的方法中

public class Listeners implements ITestListener {

Methods…
And put the screenshot code inside the method below:

@Override
    public void onTestFailure(ITestResult result) {
        code for screenshot
}

}因此我找到了一种实现屏幕截图的方法。我创建了一个截图方法。我对测试代码进行了尝试和捕获，捕获了一个异常，并调用了该方法来截图
