如何在使用 selenium 运行 testng 套件中的所有测试后关闭浏览器

Question

I have a TESTNG file like below: Where tests in credentials and checkHome are executed first before runnning DatacheckTest .

DatacheckTest.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
    <suite name="Suite">
        <suite-files>
            <suite-file
                path="./credentials.xml"></suite-file>
            <suite-file path="./checkHome.xml"></suite-file>
        </suite-files>
    
        <test thread-count="5" name="Test">
            <classes>
                <class name="DatacheckTest" />
            </classes>
        </test> <!-- Test -->
    </suite> <!-- Suite -->

All the Testng class file below extend Base which gets driver information. I want to close the browser session after running all the tests in the suite. for example when I run DatacheckTest , the Base class afterSuite methhod annotated with AfterSuite , closes browser and ends the session soon after running credentials.xml .

1. How can I make the browser close after running all tests in the suite.
2. When we are running multiple suites, close browser after everything is finished.

public class Credentials extends Base {
    @Test
    void test1() {
    }
}

public class CheckHome extends Base {
    @Test
    void test2() {
    }
}

public class DatacheckTest extends Base {
    @Test
    void test3() {
    }
}

public class Base extends {
    @AfterSuite
    public void afterSuite() {
        driver.close();
    }
}

Answer 1

@AfterSuite will not work for you, since you refer to multiple suite files and this will be invoked multiple times.

IExecutionListener in TestNG

The IExecutionListener listener monitors the start and the end of the whole TestNG execution process.

It's the most generic listener, which allows executing some code before everything and after everything .

The IExecutionListener contains two methods:

• onExecutionStart
• onExecutionFinish

You have to implement a custom ExecutionListener.

import org.testng.IExecutionListener

class ExecutionListener implements IExecutionListener {

    @Override
    public void onExecutionStart() {
        // launch driver
        System.out.println("onExecutionStart invoked");
    }

    @Override
    public void onExecutionFinish() {
        // close driver
        System.out.println("onExecutionFinish invoked");
    }
}

and apply it on Base class:

import org.testng.annotations.Listeners

@Listeners(ExecutionListener.class)
class Base {
    // some implementation
}
