2.使用testNG的TestListenerAdapter
a.先建一個(gè)類繼承TestListenerAdapter，并重寫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 創(chuàng)建時(shí)間：2015年8月24日 下午6:33:44
* 類說明
*/
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.創(chuàng)建測試類，注意需要在測試類中寫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 創(chuàng)建時(shí)間：2015年8月24日 下午6:43:44
* 類說明
*/
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文件中添加監(jiān)聽
<listeners>
<listener class-name="com.screenshot.exception.UseTestNg" />
</listeners>
3.如何將生成的圖片連接到reportNG中，將下面的代碼放入上面相應(yīng)重寫的方法中，圖片路徑與上述代碼中生成的圖片結(jié)合一起。
String imgName = "";//圖片路徑
Reporter.log("<a href=./img/" + imgName + " target=_blank>Failed Screen Shot</a>"， true);
4.使用Robot主動截圖，這種可以在自己想截圖的時(shí)候調(diào)用該方法即可截當(dāng)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創(chuàng)建時(shí)間：2015年8月26日下午7:40:34
*類說明
*/
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();
}
}
}
備注：
使用junit自動截圖，可以使用Rule，由于我用的是testNG，所以沒有調(diào)試junit的方法。詳細(xì)參考：
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();
}
}
