使用TestNG+JavaMail实现如下任务，任务要求： 请 利用面向对象的思想完成。 Demo.java所有的测试用例执行完毕后，通过TestNG监听器获取失败的测试用例类名和方法，成功的测试用例名和方法，作为文本形式发送到接收者的邮箱。 接收者的邮箱需要配置在属性文件中，类似于以下的方式 属性文件 config.properties tomail=626231936@qq.com,你自己的邮箱 public class Demo { @Test public void test1() { assertEquals(1, 1); } @Test public void test3() { assertEquals(1, 1); } @Test public void test2() { assertEquals(1, 2); } } 提示：使用TestListenerAdapter监听器的子类 要求提交监听器的相关代码。

以下是实现该任务的代码：

Demo.java：

import org.testng.Assert;
import org.testng.annotations.Test;

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

    @Test
    public void test3() {
        Assert.assertEquals(1, 1);
    }

    @Test
    public void test2() {
        Assert.assertEquals(1, 2);
    }
}

TestResultListener.java：

import org.testng.ITestContext;
import org.testng.ITestListener;
import org.testng.ITestResult;
import org.testng.xml.XmlSuite;

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.Properties;

public class TestResultListener implements ITestListener {
    private Properties properties;

    public TestResultListener() {
        properties = new Properties();
        try {
            properties.load(new FileInputStream("config.properties"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onStart(ITestContext context) {
        System.out.println("Test Suite started!");
    }

    @Override
    public void onFinish(ITestContext context) {
        System.out.println("Test Suite finished!");
        try {
            String mailContent = "Test Summary: \n\n";
            mailContent += "Passed Test Cases: \n";
            for (ITestResult result : context.getPassedTests().getAllResults()) {
                mailContent += result.getTestClass().getName() + "." + result.getName() + "\n";
            }
            mailContent += "\nFailed Test Cases: \n";
            for (ITestResult result : context.getFailedTests().getAllResults()) {
                mailContent += result.getTestClass().getName() + "." + result.getName() + "\n";
            }

            sendMail(mailContent);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onTestStart(ITestResult result) {
        System.out.println("Test case started: " + result.getTestClass().getName() + "." + result.getName());
    }

    @Override
    public void onTestSuccess(ITestResult result) {
        System.out.println("Test case passed: " + result.getTestClass().getName() + "." + result.getName());
    }

    @Override
    public void onTestFailure(ITestResult result) {
        System.out.println("Test case failed: " + result.getTestClass().getName() + "." + result.getName());
    }

    @Override
    public void onTestSkipped(ITestResult result) {
        System.out.println("Test case skipped: " + result.getTestClass().getName() + "." + result.getName());
    }

    @Override
    public void onTestFailedButWithinSuccessPercentage(ITestResult result) {
        // do nothing
    }

    @Override
    public void onStart(ISuite suite) {
        // do nothing
    }

    @Override
    public void onFinish(ISuite suite) {
        // do nothing
    }

    @Override
    public void onConfigurationSuccess(ITestResult itr) {
        // do nothing
    }

    @Override
    public void onConfigurationFailure(ITestResult itr) {
        // do nothing
    }

    @Override
    public void onConfigurationSkip(ITestResult itr) {
        // do nothing
    }

    @Override
    public void onStart(XmlSuite suite) {
        // do nothing
    }

    @Override
    public void onFinish(XmlSuite suite) {
        // do nothing
    }

    private void sendMail(String mailContent) throws MessagingException {
        String toMail = properties.getProperty("tomail");

        Properties props = new Properties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.port", "587");

        Session session = Session.getInstance(props,
                new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(properties.getProperty("frommail"), properties.getProperty("password"));
                    }
                });

        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(properties.getProperty("frommail")));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(toMail));
        message.setSubject("TestNG Test Result");
        message.setText(mailContent);

        Transport.send(message);

        System.out.println("Mail sent to " + toMail);
    }
}

config.properties：

frommail=your_email_address
password=your_email_password
tomail=recipient_email_address

在 testng.xml 中添加以下代码：

<listeners>
    <listener class-name="TestResultListener" />
</listeners>

当 Demo.java 中的测试用例执行完毕后，TestNG 会自动调用 TestResultListener 类的 onFinish 方法，该方法会获取执行结果并发送邮件。
