How can I run my classes parallelly on different browsers?

Question

I have four classes which having different test cases so I want to run them parallel on different browsers.
So I am not able to run them parallel
So I am getting different exception every time.
If you guys I have any tutorial to achieve parallel testing or any solution that would be helpful for me.

I am attaching testng.xml code.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite" thread-count="10" parallel="classes">
    <test name="ChromeTestCase">
        <parameter name="browser" value="chrome"></parameter>
        <classes>
            <class name="com.zoopla.qa.testcase.HomePageTest" />

            <class name="com.zoopla.qa.testcase.PropertyPageTest" />
            <class name="com.zoopla.qa.testcase.SalePageTest" />
            <class name="com.zoopla.qa.testcase.AgentDetailsPageTest" />
        </classes>
    </test>
    <test name="FirefoxTestCase">
        <parameter name="browser" value="FF"></parameter>
        <classes>
            <class name="com.zoopla.qa.testcase.HomePageTest" />

            <class name="com.zoopla.qa.testcase.PropertyPageTest" />
            <class name="com.zoopla.qa.testcase.SalePageTest" />
            <class name="com.zoopla.qa.testcase.AgentDetailsPageTest" />

        </classes>
    </test>
    <test name="IETestCase">
        <parameter name="browser" value="IE"></parameter>
        <classes>
            <class name="com.zoopla.qa.testcase.HomePageTest" />

            <class name="com.zoopla.qa.testcase.PropertyPageTest" />
            <class name="com.zoopla.qa.testcase.SalePageTest" />
            <class name="com.zoopla.qa.testcase.AgentDetailsPageTest" />

        </classes>
    </test>

</suite>



Below is my driver initialization class.

public class TestBase {

    public static WebDriver driver;

    public TestBase() throws IOException {

        OSName = System.getProperty("os.name");
        System.out.println(OSName);
        OSName = OSName.substring(0, 3);
        System.out.println(OSName);

        if (OSName.equalsIgnoreCase("Mac")) {
            prop = new Properties();
            System.out.println("If else");
            FileInputStream fis = new FileInputStream("./src/main/java/com/zoopla/qa/config/config.properties");
            prop.load(fis);
            System.out.println("prop loaded");

        } else if (OSName.equalsIgnoreCase("Win")) {
            System.out.println("In prop eles");
            prop = new Properties();
            FileInputStream fis = new FileInputStream(".\\src\\main\\java\\com\\zoopla\\qa\\config\\config.properties");
            prop.load(fis);
       
        }

    }

   
    public void initialization(String browserName) {

        //String browserName = prop.getProperty("browser");
        System.out.println("prop loaded" +browserName);
        if (browserName.equalsIgnoreCase("chrome")) {
            // System.setProperty("webdriver.chrome.driver", "./");
            WebDriverManager.chromedriver().setup();
            driver = new ChromeDriver();

        } else if (browserName.equalsIgnoreCase("FF")) {
               
            WebDriverManager.firefoxdriver().setup();
            driver = new FirefoxDriver();
            System.out.println("In prop eles loaded FF1");

        } else if (browserName.equalsIgnoreCase("IE")) {
            WebDriverManager.iedriver().setup();
            driver = new InternetExplorerDriver();
        } else {
            System.out.println("No browser");
        }

        driver.manage().window().maximize();
        driver.manage().deleteAllCookies();
        driver.manage().timeouts().pageLoadTimeout(60, TimeUnit.SECONDS);
        driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
        driver.get("https://www.zoopla.co.uk/");

    }
}

Can you edit your question and provide the class that starts your webdriver instance? I doubt that you have static webdriver. And when you are trying to run the class in parallel. All of them are trying to run using the same webdriver.

---

Ok, I am editing the question and yes I am using static web driver.
What is a solution for it?

Answer 1

If you are using static webdriver, you should not be using a static webdriver.

And, make sure that your webdriver is initiated and destroyed not at the class level. And you should pass the driver as a parameter to your function.

E.g.

import xyz.abc.*;

class myClass{
    static WebDriver driver;

    @BeforeTest
    public void init(){
        driver = new RemoteWebDriver();
    }
    @AfterTest 
    public void destroy(){
        driver.quit();
    }
    @Test
    public void myTest(){
        driver.get("https://www.google.com");
    }
}

//to enable parallel execution

public abstract class Base {
    @BeforeMethod
    public void _beforeTest(){
        driver = new FirefoxDriver();
        driver.navigate().to("http://localhost/");
    }
    @AfterMethod
    public void _afterTest(){
        try{
            driver.close();
        }catch(Exception ignore){
            
        }
        try{
            driver.quit();
        }catch(Exception ignore){
            
        }
    }
    
    protected WebDriver driver;
}

public class LoginTest extends Base {
    @Test
    public void sucessfullLoginTest(){
        Login login = new Login(driver);
        login.perform("qamate", "qamate");
        Assert.assertTrue(Dashboard.getWelcomeMessage(driver).getText().contains("Welcome"));
    }
    @Test
    public void rightUserNameWrongPasswordLoginTest(){
        Login login = new Login(driver);
        login.perform("qamate", "qamaet");
        Assert.assertTrue(HomePage.getErrorMessage(driver).getText().contains("Invalid credentials"));
    }
    @Test
    public void rightUserNameBlankPasswordLoginTest(){
        Login login = new Login(driver);
        login.perform("qamate", "");
        Assert.assertTrue(HomePage.getErrorMessage(driver).getText().contains("Password cannot be empty"));
    }
    @Test
    public void wrongUserNameRightPasswordLoginTest(){
        Login login = new Login(driver);
        login.perform("qamaet", "qamate");
        Assert.assertTrue(HomePage.getErrorMessage(driver).getText().contains("Invalid credentials"));
    }
    @Test
    public void wrongUserNameWrongPasswordLoginTest(){
        Login login = new Login(driver);
        login.perform("qamaet", "qamet");
        Assert.assertTrue(HomePage.getErrorMessage(driver).getText().contains("Invalid credentials"));
    }
    @Test
    public void wrongUserNameBlankPasswordLoginTest(){
        Login login = new Login(driver);
        login.perform("qamaet", "");
        Assert.assertTrue(HomePage.getErrorMessage(driver).getText().contains("Password cannot be empty"));
    }
    
    @Test
    public void blankUserNameRightPasswordLoginTest(){
        Login login = new Login(driver);
        login.perform("", "qamate");
        Assert.assertTrue(HomePage.getErrorMessage(driver).getText().contains("Username cannot be empty"));
    }
    @Test
    public void blankUserNameWrongPasswordLoginTest(){
        Login login = new Login(driver);
        login.perform("", "qamaet");
        Assert.assertTrue(HomePage.getErrorMessage(driver).getText().contains("Username cannot be empty"));
    }
    @Test
    public void blankUserNameBlankPasswordLoginTest(){
        Login login = new Login(driver);
        login.perform("", "");
        Assert.assertTrue(HomePage.getErrorMessage(driver).getText().contains("Username cannot be empty"));
    }
}

Thanks,
  I try to implement the same and let you know whether it works or not.
