testng 异常 截图

testNG里有一个异常监听类，失败时会执行类里的相关方法

DriverBase  截图类

TestngListenerScreen  异常监听类

Test1 测试类

1.DriverBase类

package com.cmall.screenshot;

import com.cmall.appium.DriverFactory;
import com.cmall.appium.Helper;
import com.cmall.jdjr.pages.Modules.Integration.HomePage;
import com.cmall.utils.LogUtil;
import com.cmall.utils.PropertyUtil;
import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.pagefactory.AppiumFieldDecorator;
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.support.PageFactory;
import org.testng.annotations.Test;

import java.io.File;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.concurrent.TimeUnit;

public class DriverBase
{

    private static AndroidDriver<MobileElement> driver = null;
    private Helper helper;
    private LogUtil log = new LogUtil(DriverBase.class);
    /**
     * 获取driver
     * */
    public AndroidDriver<MobileElement> getDriver() {
        return Test1.mdriver;
    }

    /**
     * 自动截图
     * */
    public void takeScreenShot(String methodName) {
        SimpleDateFormat sf = new SimpleDateFormat("yyyy_MM_dd_HH_mm_ss");
        Calendar cal = Calendar.getInstance();
        Date date = cal.getTime();
        String dateStr = sf.format(date);//上面几行代码的意思都是获取时间，并且格式化，用来作为图片的名称
        String path = this.getClass().getSimpleName() + "_" + methodName + "_" + dateStr + ".png";
        //因为我们截图是需要用到driver的，所以这里需要获取driver，这个driver是获取的当前对象的driver
        takeScreenShot((TakesScreenshot) this.getDriver(), path);

    }

    /**
     * 传入参数截图
     * */
    public void takeScreenShot(TakesScreenshot drivername, String path) {
        String currentPath = PropertyUtil.getString("screenPic_dir");
        File scrFile = drivername.getScreenshotAs(OutputType.FILE);
        try {
            FileUtils.copyFile(scrFile, new File(currentPath + "\" + path));
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            log.error("<a href=" + currentPath + " target=_blank>Failed Screen Shot</a>");
            System.out.println("截图成功");
        }
    }
    public void setDriver(AndroidDriver<MobileElement> driver){
        this.driver = driver;
    }
}

2.TestngListenerScreen类

package com.cmall.screenshot;

import org.testng.ITestContext;
import org.testng.ITestResult;
import org.testng.TestListenerAdapter;

public class TestngListenerScreen extends TestListenerAdapter
{
    @Override
    public void onTestSuccess(ITestResult tr)
    {
        super.onTestSuccess(tr);
    }

    // 主要是用到这个方法了，当你报错时他会监听到，然后就会执行截图操作
    @Override
    public void onTestFailure(ITestResult tr)
    {
        super.onTestFailure(tr);
        System.out.println("####################################################");
        System.out.println(tr);
        System.out.println("####################################################");
        takeScreenShot(tr,tr.getMethod().getMethodName());//第二个参数表示哪个类产生的异常
    }
    @Override
    public void onTestSkipped(ITestResult tr) {
        super.onTestSkipped(tr);
    }

    @Override
    public void onTestStart(ITestResult result) {
        super.onTestStart(result);
    }

    @Override
    public void onStart(ITestContext testContext) {
        super.onStart(testContext);
    }

    @Override
    public void onFinish(ITestContext testContext) {
        super.onFinish(testContext);
    }

    private void takeScreenShot(ITestResult tr,String methodName) {
        DriverBase driverBase = (DriverBase) tr.getInstance();
        driverBase.takeScreenShot(methodName);

    }
}

3.Test1测试类

package com.cmall.screenshot;

import com.cmall.appium.DriverFactory;
import com.cmall.appium.Helper;
import com.cmall.appium.MultideviceManage;
import com.cmall.http.LogUtil;
import com.cmall.jdjr.pages.Modules.Integration.HomePage;
import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.pagefactory.AppiumFieldDecorator;
import org.openqa.selenium.support.PageFactory;
import org.testng.annotations.Listeners;

import java.util.concurrent.TimeUnit;
import org.testng.annotations.Test;

@Listeners({ TestngListenerScreen.class })
public class Test1 extends DriverBase
{
    static AndroidDriver<MobileElement> mdriver = null;
    private LogUtil log = new LogUtil(Test.class);
    MultideviceManage m = new MultideviceManage();
    Helper helper;
    public Test1(){
        log.info("---------屏幕截图测试类---------------");
    }
    @Test
    public void test(){
        mdriver = DriverFactory.initDriver(4723,"TWGDU16B26001079");
        HomePage homePage = new HomePage();
        PageFactory.initElements(new AppiumFieldDecorator(mdriver, 20 , TimeUnit.SECONDS), homePage);
        // int a=1/0;//没预测到的--会截图
        try {
            Thread.sleep(2000);
            helper = new Helper(mdriver);
            helper.clickonElement(homePage.精选);
           // Assert.assertEquals(1,2);//会截图
            //throw new IllegalArgumentException("参数长度不是7位"); //不会截图
            int b=1/0;//能预测到被catch到的 不会截图
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

 4.配置xml文件

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="TestngListenerScreen" verbose="1" >
<listeners>
    <listener class-name="com.cmall.screenshot.TestngListenerScreen"></listener>
</listeners>
<test name = "Test" >
    <classes>
        <class name="com.cmall.screenshot.ScreenTest"/>
    </classes>
</test>
</suite>

5.把xml文件配置在pom.xml里
