截图

package com.zhongxin.demo;

import com.zhongxin.common.BaseCase;
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.testng.annotations.Test;

import java.io.File;

public class ScreenShotDemo extends BaseCase {
    @Test
    public void test() throws Exception {
        WebDriver driver = open("chrome");
        driver.get("htts://www.baidu.com");
        Thread.sleep(2000);
        TakesScreenshot screenshot = (TakesScreenshot) driver;
        File file = screenshot.getScreenshotAs(OutputType.FILE);
        System.out.println(file.getAbsoluteFile());
        File destFile = new File("aaa.png");
        FileUtils.moveFile(file, destFile);
        close(driver);
    }
}

强制类型转换driver

TakesScreenshot screenshot = (TakesScreenshot) driver;

在执行测试的时候，使用截图的场景为：当执行失败的时候进行截图

需要使用监听，判断执行是否成功

package com.zhongxin.listeners;

import com.zhongxin.cases.LoginCase;
import com.zhongxin.common.BaseCase;
import com.zhongxin.utils.ScreenShotUtils;
import org.testng.IHookCallBack;
import org.testng.IHookable;
import org.testng.ITestResult;

public class ScreenShotListener implements IHookable {
    @Override
    public void run(IHookCallBack iHookCallBack, ITestResult iTestResult) {
        // iHookCallBack 用例执行@Test方法的
        // iTestResult @Test方法的结果(@Test对象/方法名/是否抛出异常)
        iHookCallBack.runTestMethod(iTestResult);
        Throwable throwable = iTestResult.getThrowable();
        if (throwable != null) {
            //throwable不等于异常说明@Test出现异常了，执行截图
            Object object = iTestResult.getInstance();
            BaseCase logincase = (BaseCase) object;
            //获取当前@Test方法名
            String methodName = iTestResult.getName();
            //获取当前@Test类名
            String className = iTestResult.getInstanceName();
            String destFilename = className + "_" + methodName + "_" + System.currentTimeMillis() + ".png";
            ScreenShotUtils.screenShot(logincase.driver, destFilename);
        }

    }
}

在testng.xml中添加

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="futureloan">
    <listeners>
        <listener class-name="com.zhongxin.listeners.ScreenShotListener"></listener>
    </listeners>
    <test name="登录测试">
        <classes>
            <class name="com.zhongxin.cases.LoginCase"></class>
        </classes>
    </test>
</suite>

将截图展示在Allure报告中

package com.zhongxin.listeners;

import com.zhongxin.common.BaseCase;
import io.qameta.allure.Attachment;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.testng.IHookCallBack;
import org.testng.IHookable;
import org.testng.ITestResult;

public class AllureReportListener implements IHookable {

    @Attachment(value = "Page screenshot", type = "image/png")
    public byte[] saveScreenshot(byte[] screenShot) {
        return screenShot;
    }

    @Override
    public void run(IHookCallBack iHookCallBack, ITestResult iTestResult) {
        iHookCallBack.runTestMethod(iTestResult);
        Throwable throwable = iTestResult.getThrowable();
        if (throwable != null) {
            //throwable不等于异常说明@Test出现异常了，执行截图
            Object object = iTestResult.getInstance();
            BaseCase baseCase = (BaseCase) object;
            TakesScreenshot screenshot = (TakesScreenshot) baseCase.driver;
            byte[] screenshotAs = screenshot.getScreenshotAs(OutputType.BYTES);
            saveScreenshot(screenshotAs);
        }
    }
}

在testng.xml中

<listeners>
    <listener class-name="com.zhongxin.listeners.AllureReportListener"></listener>
</listeners>

重试

package com.zhongxin.listeners;

import org.testng.IRetryAnalyzer;
import org.testng.ITestResult;

public class MyRetry implements IRetryAnalyzer {
    private int retryCount = 0;//当前重试次数
    private static final int maxRetryCount = 3;//最大重试次数

    @Override
    public boolean retry(ITestResult iTestResult) {
        if (retryCount < maxRetryCount) {
            retryCount++;
            return true;
        }
        return false;
    }
}

在测试代码头部增加

@Test(retryAnalyzer = MyRetry.class)

全部添加重试

package com.zhongxin.listeners;

import com.zhongxin.common.BaseCase;
import io.qameta.allure.Attachment;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.testng.IHookCallBack;
import org.testng.IHookable;
import org.testng.ITestResult;

public class AllureReportListener implements IHookable {

    @Attachment(value = "Page screenshot", type = "image/png")
    public byte[] saveScreenshot(byte[] screenShot) {
        return screenShot;
    }

    @Override
    public void run(IHookCallBack iHookCallBack, ITestResult iTestResult) {
        iHookCallBack.runTestMethod(iTestResult);
        Throwable throwable = iTestResult.getThrowable();
        if (throwable != null) {
            //throwable不等于异常说明@Test出现异常了，执行截图
            Object object = iTestResult.getInstance();
            BaseCase baseCase = (BaseCase) object;
            TakesScreenshot screenshot = (TakesScreenshot) baseCase.driver;
            byte[] screenshotAs = screenshot.getScreenshotAs(OutputType.BYTES);
            saveScreenshot(screenshotAs);
        }
    }
}

在testng.xml中

<listener class-name="com.zhongxin.listeners.RetryListener"></listener>
