How do I execute multiple test class parallely. which using same function in another class using testng

Question

How can I execute multiple test class 'test1' and 'test2' parallely? Which is using the same function in another class using TestNG.

When I define the parallel option as 'classes' and thread-count as '2' in TestNG XML, the login page is loading two times, but 'sendelement' method is executing in single browser two times simultaneously.

for eg; if my login is 'user1', sendelement function execute two times as 'user1user1' in the username field and shows invalid login.

 {
 webdriverCommon.windowMaximise();
 webdriverCommon.sendElement(CommonRepo.userName_Edit, strUserName);
 webdriverCommon.sendElement(CommonRepo.password_Edit, strPassword);
 webdriverCommon.clickElement(CommonRepo.logginButton_buttton);
 }
}

• FDM: Where do your username and password come from? I don't see that data anywhere.
• sreelakshmi: strUserName,strPassword are username, password variables.. CommonRepo.userName_Edit and CommonRepo.userName_Edit are the By elements for input fields in UI
• FDM: Can you show the actual test class where you pass the data?

It looks like you are using one webDriver, webdriverCommon. You'll need to setup your framework such that each class or test uses its own driver. I have a TestBase class that each test class inherits from. The following example is using JUnit but the idea is the same.

public class TestBase {
 protected WebDriver driver;
 protected String baseUrl = "http://example.com/";
 protected String hubUrl = "http://localhost:4444/wd/hub";
 @Before
 public void setUp() throws Exception{
 try {
 DesiredCapabilities capability = DesiredCapabilities.chrome();
 driver = new RemoteWebDriver(new URL(hubUrl), capability);
 }
 catch (Exception e){
 System.setProperty("webdriver.chrome.driver", "C:\\Selenium\\chromedriver.exe");
 driver = new ChromeDriver();
 }
 driver.manage().deleteAllCookies();
 driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
 }
 @After
 public void tearDown() throws Exception{
 driver.quit();
 }
}
