How To Prioritise The Test Cases Using TestNG Priority keyword

We all know basic use of TestNG and use it for Automation testing Script, but simply using TestNG @Test annotation has one issue in its by default settings.

@Test, by default, executes the tests in Alphabetic order.

So, we need to use ordering of tests as per our requirement and we need to use a keyword "priority" to achieve this.

We can assign the order of tests starting from zero(0).

Syntax for which can be given as:

@Test(priority = o)

Let us look for full example for prioritizing the test cases:

package exampleTestPriority; import org.openqa.selenium.WebDriver; import org.testng.annotations.Test; public class TestCases { public WebDriver driver; @Test(priority = 0) public void One_1() { System.out.println("Test Case number One(1)"); } @Test(priority = 1) public void Two_2() { System.out.println("Test Case number Two(2)"); } @Test(priority = 2) public void Three_3() { System.out.println("Test Case number Three(3)"); } @Test(priority = 3) public void Four_4() { System.out.println("Test Case number Four(4)"); } }

and output will show:

Test Case number One(1) Test Case number Two(2) Test Case number Three(3) Test Case number Four(4) Passed: One_1 Passed: Two_2 Passed: Three_3 Passed: Four_4

Thanks.
