1 通过实现ITestListener的方法添加Reporter log

TestNG的Listener列表

TestNG提供了一组预定义的Listener Java接口，这些接口全部继承自TestNG的 ITestNGListener接口。用户创建这些接口的实现类，并把它们加入到 TestNG 中，TestNG便会在测试运行的不同时刻调用这些类中的接口方法:

IExecutionListener 监听TestNG运行的启动和停止。
IAnnotationTransformer 注解转换器，用于TestNG测试类中的注解。
ISuiteListener 测试套件监听器，监听测试套件的启动和停止。
ITestListener 测试方法执行监听。
IConfigurationListener 监听配置方法相关的接口。
IMethodInterceptor 拦截器，调整测试方法的执行顺序。
IInvokedMethodListener 测试方法拦截监听，用于获取被TestNG调用的在Method的Before 和After方法监听器。该方法只会被配置和测试方法调用。
IHookable 若测试类实现了该接口，当@Test方法被发现时，它的run()方法将会被调用来替代@Test方法。这个测试方法通常在IHookCallBack的callback之上调用，比较适用于需要JASS授权的测试类。
IReporter 实现该接口可以生成一份测试报告。

本文将着重介绍最常用到的两个Listener ITestListener与Ireporter接口。

1.1 MyTestListener设置

通过实现ITestListener的方法，添加Reporter.log

MyTestListener.java

import org.testng.ITestContext;
import org.testng.ITestListener;
import org.testng.ITestResult;
import org.testng.Reporter;public class MyTestListener implements ITestListener {//用例执行结束后，用例执行成功时调用public void onTestSuccess(ITestResult tr) {logTestEnd(tr, "Success");}//用例执行结束后，用例执行失败时调用public void onTestFailure(ITestResult tr) {logTestEnd(tr, "Failed");}//用例执行结束后，用例执行skip时调用public void onTestSkipped(ITestResult tr) {logTestEnd(tr, "Skipped");}//每次方法失败但是已经使用successPercentage进行注释时调用，并且此失败仍保留在请求的成功百分比之内。public void onTestFailedButWithinSuccessPercentage(ITestResult tr) {logTestEnd(tr, "FailedButWithinSuccessPercentage");}//每次调用测试@Test之前调用public void onTestStart(ITestResult result) {logTestStart(result);}//在测试类被实例化之后调用，并在调用任何配置方法之前调用。public void onStart(ITestContext context) {return;}//在所有测试运行之后调用，并且所有的配置方法都被调用public void onFinish(ITestContext context) {return;}// 在用例执行结束时，打印用例的执行结果信息protected void logTestEnd(ITestResult tr, String result) {Reporter.log(String.format("-------------Result: %s-------------", result), true);}// 在用例开始时，打印用例的一些信息，比如@Test对应的方法名，用例的描述等等protected void logTestStart(ITestResult tr) {Reporter.log(String.format("-------------Run: %s.%s---------------", tr.getTestClass().getName(), tr.getMethod().getMethodName()), true);Reporter.log(String.format("用例描述: %s, 优先级: %s", tr.getMethod().getDescription(), tr.getMethod().getPriority()),true);return;}
}

1.2 输出结果

SmkDemo1.java

import com.demo.listener.MyTestListener;
import org.testng.Assert;
import org.testng.Reporter;
import org.testng.annotations.Listeners;
import org.testng.annotations.Test;@Listeners({MyTestListener.class})
public class SmkDemo1 {@Test(description="测testPass11的描述",priority = 1,groups = {"分组1"})public void testPass11(){Reporter.log("Test11的第一步",true);Assert.assertEquals(1,1);}
}

ExtentReports 另一种方法

引言

在走进Java接口测试之测试框架TestNG 中我们详细介绍了 TestNG 的各种用法，在本文中，我将详细介绍如何将 ExtentReports 测试报告与TestNG集成。

ExtentReports 简介

主要特点：

生成的报告简洁美观
生成的单html方便 Jenkins 集成发邮件
自带集中展示历史报告的服务端
支持 Java 和 .Net

TestNG 原生报告有点丑，信息整理有点乱。ExtentReports 是用于替换TestNG 原生报告。当然也可以使用 ReportNg，个人偏好 ExtentReports 样式。

官网已经给了很多demo了，大家可以参考练习。

官网：http://extentreports.com/

客户端：

https://github.com/anshooarora/extentreports-java/commits/master

服务端:https://github.com/anshooarora/extentx

Step-1：添加 Maven 依赖包

引入pom.xml

<!--引入extentreports相关包--><dependency><groupId>com.aventstack</groupId><artifactId>extentreports</artifactId><version>3.1.5</version><scope>provided</scope></dependency><dependency><groupId>com.vimalselvam</groupId><artifactId>testng-extentsreport</artifactId><version>1.3.1</version></dependency><dependency><groupId>com.relevantcodes</groupId><artifactId>extentreports</artifactId><version>2.41.2</version></dependency><!--引入testng测试框架--><dependency><groupId>org.testng</groupId><artifactId>testng</artifactId><version>6.14.3</version><scope>compile</scope></dependency>

Step-2：重写 ExtentTestNgFormatter 类

主要基于以下两项原因：

支持报告中展示更多状态类型的测试结果，例如：成功、失败、警告、跳过等。
因为不支持cdn.rawgit.com访问，故替css访问方式。

创建 MyExtentTestNgFormatter 类

下载 ExtentReportes 源码，找到 ExtentTestNgFormatter 类，Listener 目录下创建 MyExtentTestNgFormatter.java 类直接继承 ExtentTestNgFormatter 类。

public class MyExtentTestNgFormatter extends ExtentTestNgFormatter {

解决CDN无法访问

构造方法加入

htmlReporter.config().setResourceCDN(ResourceCDN.EXTENTREPORTS);

具体代码如下：

public MyExtentTestNgFormatter() {setInstance(this);testRunnerOutput = new ArrayList<>();String reportPathStr = System.getProperty("reportPath");File reportPath;try {reportPath = new File(reportPathStr);} catch (NullPointerException e) {reportPath = new File(TestNG.DEFAULT_OUTPUTDIR);}if (!reportPath.exists()) {if (!reportPath.mkdirs()) {throw new RuntimeException("Failed to create output run directory");}}File reportFile = new File(reportPath, "report.html");File emailReportFile = new File(reportPath, "emailable-report.html");htmlReporter = new ExtentHtmlReporter(reportFile);EmailReporter emailReporter = new EmailReporter(emailReportFile);reporter = new ExtentReports();//        如果cdn.rawgit.com访问不了，可以设置为：ResourceCDN.EXTENTREPORTS或者ResourceCDN.GITHUBhtmlReporter.config().setResourceCDN(ResourceCDN.EXTENTREPORTS);reporter.attachReporter(htmlReporter, emailReporter);}

重写 onstart 方法

新建一个类名为MyReporter，一个静态ExtentTest的引用。

Listener 包下 MyReporter.java

public class MyReporter { public static ExtentTest report; }

MyExtentTestNgFormatter.java

public void onStart(ITestContext iTestContext) {ISuite iSuite = iTestContext.getSuite();ExtentTest suite = (ExtentTest) iSuite.getAttribute(SUITE_ATTR);ExtentTest testContext = suite.createNode(iTestContext.getName());// 将MyReporter.report静态引用赋值为testContext。// testContext是@Test每个测试用例时需要的。report.log可以跟随具体的测试用例。另请查阅源码。MyReporter.report = testContext;iTestContext.setAttribute("testContext", testContext);}

自定义配置

测试报告默认是在工程根目录下创建 test-output/ 文件夹下，名为 report.html、 emailable-report.html。可根据各自需求在构造方法中修改。

public MyExtentTestNgFormatter() {setInstance(this);testRunnerOutput = new ArrayList<>();// reportPath报告路径String reportPathStr = System.getProperty("reportPath");File reportPath;try {reportPath = new File(reportPathStr);} catch (NullPointerException e) {reportPath = new File(TestNG.DEFAULT_OUTPUTDIR);}if (!reportPath.exists()) {if (!reportPath.mkdirs()) {throw new RuntimeException("Failed to create output run directory");}}// 报告名report.htmlFile reportFile = new File(reportPath, "report.html");// 邮件报告名emailable-report.htmlFile emailReportFile = new File(reportPath, "emailable-report.html");htmlReporter = new ExtentHtmlReporter(reportFile);EmailReporter emailReporter = new EmailReporter(emailReportFile);reporter = new ExtentReports();reporter.attachReporter(htmlReporter, emailReporter);}

report.log

report.log 支持多种玩法

// 根据状态不同添加报告。型如警告 MyReporter.report.log(Status.WARNING, "接口耗时(ms)：" + String.valueOf(time));

直接从TestClass 中运行时会报 MyReporter.report 的空指针错误，需做判空处理。

}class MyReporter {public static ExtentTest report;private static String testName;public static String getTestName() {return testName;}public static void setTestName(String testName) {MyReporter.testName = testName;}
}

Step-3：配置监听

在测试集合 testng.xml 文件中导入 Listener 监听类。

<listeners> <listener class-name="com.zuozewei.extentreportdemo.listener.MyExtentTestNgFormatter"/> </listeners>

Step-4：配置报告

extent reporters支持报告的配置。目前支持的配置内容有title、主题等。先在 src/resources/目录下添加 config/report/extent-config.xml。

<?xml version="1.0" encoding="UTF-8"?>
<extentreports><configuration><timeStampFormat>yyyy-MM-dd HH:mm:ss</timeStampFormat><!-- report theme --><!-- standard, dark 个人喜好暗色 --><theme>dark</theme><!-- document encoding --><!-- defaults to UTF-8 --><encoding>UTF-8</encoding><!-- protocol for script and stylesheets --><!-- defaults to https --><protocol>https</protocol><!-- title of the document --><documentTitle>接口自动化测试报告</documentTitle><!-- report name - displayed at top-nav --><reportName>接口自动化测试报告</reportName><!-- report headline - displayed at top-nav, after reportHeadline --><reportHeadline>接口自动化测试报告</reportHeadline><!-- global date format override --><!-- defaults to yyyy-MM-dd --><dateFormat>yyyy-MM-dd</dateFormat><!-- global time format override --><!-- defaults to HH:mm:ss --><timeFormat>HH:mm:ss</timeFormat><!-- custom javascript --><scripts><![CDATA[$(document).ready(function() {});]]></scripts><!-- custom styles --><styles><![CDATA[]]></styles></configuration>
</extentreports>

Step-5：配置系统

config下新建 MySystemInfo类继承 SystemInfo 接口

public class MySystemInfo implements SystemInfo {@Overridepublic Map<String, String> getSystemInfo() {Map<String, String> systemInfo = new HashMap<>();systemInfo.put("测试人员", "zuozewei");return systemInfo;}
}

可用于添加系统信息，例如：db的配置信息，人员信息，环境信息等。根据项目实际情况添加。

至此，extentreports 美化报告完成。

Step-6：添加测试用例

public class TestMethodsDemo {@Testpublic void test1(){Assert.assertEquals(1,2);}@Testpublic void test2(){Assert.assertEquals(1,1);}@Testpublic void test3(){Assert.assertEquals("aaa","aaa");}@Testpublic void logDemo(){Reporter.log("这是故意写入的日志");throw new RuntimeException("故意运行时异常");}
}

Step-7：测试用例suite

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" ><suite name="测试demo" verbose="1" preserve-order="true"><parameter name="report.config" value="src/main/resources/report/extent-config.xml"/><parameter name="system.info" value="com.zuozewei.extentreportdemo.config.MySystemInfo"/><test name="测试demo" preserve-order="true"><classes><class name="com.zuozewei.extentreportdemo.testCase.TestMethodsDemo"/></classes></test><listeners><listener class-name="com.zuozewei.extentreportdemo.listener.MyExtentTestNgFormatter"/></listeners>
</suite>
