并行测试期间测试失败后如何关闭浏览器

Question

Trying to close the browser when a test fails in Selenium. Tried to include an AfterMethod but not browser is still not closing on fail. Any help would be greatly appreciated!

Here is my java class:

public class googleTestClass extends Methods{

public void executeGoogle() throws InterruptedException {
    this.goToURL("https://www.google.com");
    this.enterValue("name","q","google test 1");
}

@Test
public void test1() throws InterruptedException {

    googleTestClass object1;
    object1 = new googleTestClass();
    object1.launchBrowser();
    object1.executeGoogle();
}

@Test
public void test2() throws InterruptedException {

    googleTestClass object2;
    object2 = new googleTestClass();
    object2.launchBrowser();
    object2.executeGoogle();
}

@AfterMethod
public void tearDown() throws InterruptedException, IOException {
    driver.quit();
}
} 

Here is the mentioned Methods class: // import statements

public class Methods {

public WebDriver driver;

public void launchBrowser() {System.setProperty("webdriver.chrome.driver","C:\\chromedriver_win32\\chromedriver.exe");

    driver = new ChromeDriver();
}

public void goToURL(String url) {
    driver.get(url);
}

    public void enterValue(String htmltype, String identifier, String value) throws InterruptedException {
    if (htmltype == "id") {
        WebElement element = driver.findElement(By.id(identifier));
        element.clear();
        element.sendKeys(value);
        element.submit();
    }
    if (htmltype =="name") {
        WebElement element = driver.findElement(By.name(identifier));
        element.clear();
        element.sendKeys(value);
        element.submit();
    }

    Thread.sleep(3000);
}

Here is the used testNG file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite" parallel="methods">

  <test thread-count="5" name="Test" parallel="methods">
    <classes>
         <class name="webDrivertests.googleTestClass">
            <methods>
                <include name ="test1"/>
                <include name ="test2"/>
            </methods>
        </class>
    </classes>
  </test> <!-- Test -->
</suite> <!-- Suite -->

Is the AfterMethod not being reached because it is written incorrectly or does the problem lies in driver.quit? Any help would be great. Thank you!

Answer 1

The problem is that when you run the Test class and @AfterMethod is called, it is trying to quit from the driver that belongs to the top class but not to the classes which are instantiated inside the methods. Here is a small example for better understanding :

JUnit test class :

import org.junit.Test;
import org.junit.After;

public class intTestClass extends Methods{

    @Test
    public void test1() throws InterruptedException {
        intTestClass object1;
        object1 = new intTestClass();
        object1.setInt();
    }

    @After
    public void tearDown() {
        System.out.println("testInt is: "+ testInt);
    }
}

And the Methods class :

public class Methods {

    public int testInt = 0;

    public void setInt() {
        testInt = 1;
    }

}

Here, when you run the JUnit test, what you expect is that the testInt value to be printed as 1. However, the method with the annotation @After(@AfterMethod for testng) checks the value of the testInt variable which belongs to the top level intTestClass rather than the intTestClass that is instantiated inside the test1() method.

Therefore, we see the output as :

testInt is: 0

If we apply this to your scenario, what you need to do is that move your launchBrowser() method inside your test class and call the method with an @BeforeClass annotation.
