Below is my XML piece.

<?xml version="1.0" encoding="UTF-8"?> <suite name='Automation' threadCount="5" parallel="methods"> <tests> <parameter name='clientName' value='Five' /> <test name='PA'> <classes> <class name='TC_INC_1'> </class> </classes> </test>

So I am loading the required data from excel through DATA PROVIDER in TestNg. What I wanted to achieve is to run each row in different threads. Lets say I had 5 rows of data

1- Go to Google.com 2- Go to Facebook.com 3- Go to Dollarama.com 4- Go to Walmart.com 5- Go to KegSteak.com

And say I am running two thread means two browsers. I want both browsers run parallelly executing each of the row in any sequence.

Thread 1 - 1- Go to Google.com Thread 2- 2- Go to Facebook.com First test done - browser closed and opens again.

Now it should pick the 3 and fourth row. Thread 1 - 3- Go to Dollarama.com Thread 2- 4- Go to Walmart.com

browser closed and opens again. Thread 1 - 5- Go to KegSteak.com

What I actually see is two browsers open and one of the browser runs the url and the other just becomes static after launching chrome.

Any fixes ?

With Local WebDriver variable

Make sure, you launch and tear-down your WebDriver within a test method:

 @Test(dataProvider = "provideUrls") public void navigateByUrlTest(String url){ WebDriver driver = ... driver.get(url); // do something driver.quit(); } //I know this implemented to get data from Excel, but just for example.. @DataProvider(parallel = true) public Object[][] provideUrls() { return new Object [][] { {"https://google.com"}, {"https://facebook.com"}, {"https://dollarama.com"}, {"https://walmart.com"}, {"https://kegSteak.com"} }; }

With Global Thread-Safe WebDriver variable

WebDriver configuration can be moved to @BeforeMethod/@AfterMethod methods.

NOTE: ThreadLocal wrapper should be used for WebDriver instance in this case. This ensures we will keep separate WebDriver instances per each thread.

 protected ThreadLocal<WebDriver> driverThreadSafe = new ThreadLocal<WebDriver>(); @BeforeMethod public void launchDriver() { driverThreadSafe.set(new ChromeDriver()); } @AfterMethod public void quitDriver() { driverThreadSafe.get().quit(); } @Test(dataProvider = "provideUrls") public void test(String url){ WebDriver driver = driverThreadSafe.get(); driver.get(url); // do something, but do not quit the driver }

Configure Threads Count

<suite name='Automation' threadCount="5" - this will not work for DaraProvider parallelism.

You have to pass dataproviderthreadcount testNG argument with thread count for data-provider.

e.g. programmatically, add this method to the current class (or parent base test class)

 @BeforeSuite public void setDataProviderThreadCount(ITestContext context) { context.getCurrentXmlTest().getSuite().setDataProviderThreadCount(5); }
