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.GITHUB
      htmlReporter.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.html
        File reportFile = new File(reportPath, "report.html");
        // 邮件报告名emailable-report.html
        File 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。

        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 {
    @Override
    public 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 {

    @Test
    public void test1(){
        Assert.assertEquals(1,2);
    }

    @Test
    public void test2(){
        Assert.assertEquals(1,1);
    }


    @Test
    public void test3(){
        Assert.assertEquals("aaa","aaa");
    }


    @Test
    public 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>
