testng对失败时截图处理

1.截图类:

public class ScreenShot {
	public WebDriver driver;

	public ScreenShot(WebDriver driver) {
		this.driver = driver;
	}

	private void takeScreenshot(String screenPath) {
		try {
			File scrFile = ((TakesScreenshot) driver)
					.getScreenshotAs(OutputType.FILE);
			FileUtils.copyFile(scrFile, new File(screenPath));
		} catch (IOException e) {
			System.out.println("Screen shot error: " + screenPath);
		}
	}

	public void takeScreenshot() {
		String screenName = String.valueOf(new Date().getTime()) + ".jpg";
		File dir = new File("test-output/snapshot");
		if (!dir.exists())
			dir.mkdirs();
		String screenPath = dir.getAbsolutePath() + "/" + screenName;
		this.takeScreenshot(screenPath);		
	}
}

 2.我们可以用testng的一个监听器来监听错误时截图:

public class DotTestListener extends TestListenerAdapter {

	@Override
	public void onTestFailure(ITestResult tr) {		
		
	}

}

 3.也就是说我们只需要在onTestFailure方法里面调用ScreenShot类里面的takeScreenshot方法即可,但是我们注意到ScreenShot类里需要传一个driver进去。

现在问题来了,对于driver的处理,各式各样,有的用到了单子模式,即把driver当成一个全局的静态变量,在哪都可以用,所以ScreenShot类里可以访问得到driver对象,但这样也就有一个问题,即全局只有一个driver,如果想多线程运行时,启多个driver实例时,用这种方式就做不到了,于是出现了另外一种处理方式,即每一个类或者每一个测试方法是,启一个新的driver对象,这样,driver对象就不是全局的了,就是类对象属性了,比如:

public class TestBase {
	
	public WebDriver driver;	
	
	public WebDriver getDriver() {
		return driver;
	}

	@BeforeClass
	public void setUp(){
		driver = new FirefoxDriver();
		driver.manage().window().maximize();
		driver.navigate().to("http://www.baidu.com");		
	}
	
	@AfterClass
	public void tearDown(){
		driver.close();
		driver.quit();
	}
}

 

public class Test10 extends TestBase{	
	
	@Test
	public void testInput(){
		System.out.println(5/0);
	}	
	
}

 那如何把这个类对象的driver属性给传到onTestFailure方法里去?

public class DotTestListener extends TestListenerAdapter {

	@Override
	public void onTestFailure(ITestResult tr) {		
		try {
			TestBase tb = (TestBase) tr.getInstance();
			WebDriver driver = tb.getDriver();			
			System.out.println(driver.getTitle());
		} catch (SecurityException e) {
			e.printStackTrace();
		} catch (IllegalArgumentException e) {			
			e.printStackTrace();
		}
	}

}

 最后再加上监听即可:

@Listeners({ DotTestListener.class })
public class Test10 extends TestBase{	
	
	@Test
	public void testInput(){
		System.out.println(5/0);
	}	
	
}
