Selenium遇到异常自动截图-自动化测试

更新时间:2022-04-26 09:27:02 作者:多测师 浏览:119

  最近要在框架中添加case失败时,要自动截图,今天做下总结。

  1.只针对webdriver的异常截图,重写onException,该方法由于只针对webdriver抛的异常时才能截图,有一定的限制

  public void onException(java.lang.Throwable throwable,

  WebDriver driver){

  Throwable cause = throwable.getCause();

  /*

  String cause = throwable.getClass().getName();

  ScreenshotException ec = new ScreenshotException(cause);

  */

  System.out.println(throwable.getClass().getName());

  System.out.println("onException=" + cause);

  Date currentTime = new Date();

  SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd-hh-mm-ss");

  String dateString = formatter.format(currentTime);

  File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

  try {

  File screenshot = new File("D:/ddd/"

  + dateString + ".png");

  FileUtils.copyFile(scrFile,screenshot);

  } catch (IOException e) {

  e.printStackTrace();

  }

  }

  测试类,要用EventFiringWebDriver ,并注册MyListen

  public static void main(String args[]) {

  String key = "webdriver.chrome.driver";

  String value = "D:/BaiduYunDownload/selenium/chromedriver.exe";

  System.setProperty(key, value);

  WebDriver dr = new ChromeDriver();

  EventFiringWebDriver event = new EventFiringWebDriver(dr);

  MyListen ml = new MyListen();

  event.register(ml);

  dr = event;

  dr.get("http://www.baidu.com");

  dr.findElement(By.id("kw1")).sendKeys("test");

  //System.out.println(5/0);

  Assert.assertEquals("haha", event.findElement(By.id("su")).getAttribute("value"));

  event.quit();

  }

  2.使用testNG的TestListenerAdapter

  a.先建一个类继承TestListenerAdapter,并重写onTestFailure方法

  package com.screenshot.exception;

  import java.io.File;

  import java.io.IOException;

  import java.text.SimpleDateFormat;

  import java.util.Date;

  import org.apache.commons.io.FileUtils;

  import org.apache.velocity.runtime.log.LogManager;

  import org.openqa.selenium.OutputType;

  import org.openqa.selenium.TakesScreenshot;

  import org.openqa.selenium.WebDriver;

  import org.testng.ITestResult;

  import org.testng.TestListenerAdapter;

  import com.screenshot.singleton.TestBase;

  /**

  * @author QiaoJiaofei

  * @version 创建时间:2022年4月26日

  * 类说明

  */

  public class UseTestNg extends TestListenerAdapter{

  @Override

  public synchronized void onTestFailure(ITestResult result) {

  Object currentClass = result.getInstance();

  WebDriver webDriver = ((TestUsNg) currentClass).getDriver();

  if (webDriver != null)

  {

  Date currentTime = new Date();

  SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd-hh-mm-ss");

  String dateString = formatter.format(currentTime);

  File scrFile = ((TakesScreenshot) webDriver).getScreenshotAs(OutputType.FILE);

  try {

  File screenshot = new File("D:/ddd/"

  + dateString + ".png");

  FileUtils.copyFile(scrFile,screenshot);

  } catch (IOException e) {

  e.printStackTrace();

  }

  }

  }

  }

  b.创建测试类,注意需要在测试类中写getDriver()方法

  package com.screenshot.exception;

  import org.openqa.selenium.WebDriver;

  import org.openqa.selenium.chrome.ChromeDriver;

  import org.testng.annotations.Test;

  /**

  * @author QiaoJiaofei

  * @version 创建时间:2022年4月26日

  * 类说明

  */

  public class TestUsNg {

  private WebDriver dr;

  public WebDriver getDriver() {

  return dr;

  }

  @Test

  public void f() {

  String key = "webdriver.chrome.driver";

  String value = "D:/BaiduYunDownload/selenium/chromedriver.exe";

  System.setProperty(key, value);

  dr = new ChromeDriver();

  System.out.println(5/0);

  }

  }

  C.在testng的xml文件中添加监听

  3.如何将生成的图片连接到reportNG中,将下面的代码放入上面相应重写的方法中,图片路径与上述代码中生成的图片结合一起。

  String imgName = "";//图片路径

  Reporter.log("Failed Screen Shot", true);

  4.使用Robot主动截图,这种可以在自己想截图的时候调用该方法即可截当前界面

  packagecom.screenshot.book;

  importjava.awt.Rectangle;

  importjava.awt.Robot;

  importjava.awt.Toolkit;

  importjava.awt.image.BufferedImage;

  importjava.io.File;

  importjavax.imageio.ImageIO;

  importorg.testng.annotations.Test;

  /**

  *@authorQiaoJiaofei

  *@version创建时间:2022年4月26日

  *类说明

  */

  publicclassTestRobot{

  @Test

  publicvoidtakeScreenShotMethod(){

  try{

  Thread.sleep(3000);

  BufferedImageimage=newRobot().createScreenCapture(newRectangle(Toolkit.getDefaultToolkit().getScreenSize()));

  ImageIO.write(image,"jpg",newFile("D:/ddd/screenshot.jpg"));

  }

  catch(Exceptione){

  e.printStackTrace();

  }

  }

  }

  备注:

  使用junit自动截图,可以使用Rule,由于我用的是testNG,所以没有调试junit的方法。详细参考:http://stackoverflow.com/questions/20995722/when-does-

  onexception-get-triggered-in-webdrivereventlistener

  @Rule

  public TestRule testWatcher = new TestWatcher() {

  @Override

  public void succeeded(Description test){

  for (LogEntry log : driver.manage().logs().get(LogType.DRIVER).getAll()) {

  System.out.println("Level:" + log.getLevel().getName());

  System.out.println("Message:" + log.getMessage());

  System.out.println("Time:" + log.getTimestamp());

  System.out.println("-----------------------------------------------");

  }

  System.out.println();

  @Override

  public void failed(Throwable t, Description test) {

  String testName = test.getClassName();

  String subTestName = test.getMethodName();

  String screenShotName = String.format("%s\\%s", testName, screenShotName);

  if (driver instanceof TakesScreenshot) {

  File tempFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

  try {

  System.out.println(">>>>>>>>>>LOGS: " + yourDirForImages + "\\" + screenShotName + ".png");

  FileUtils.copyFile(tempFile, new File(String.format("%s.png", screenShotName)));

  } catch (IOException e) {

  e.printStackTrace();

  }

  }
