As we know testNG test methods are executed in alphabetical order by default, but testNG provides priority keyword to prioritize test case execution order and the value starts from -n to n…
Priority value starts from any number from -ve to +ve, 0 is default (if nothing is set)
For a method less priority number, executes first
| TestCase | Priority |
| tc1 | |
| tc2 | -1 |
| tc3 | -2 |
| tc4 | 2 |
| tc5 | 1 |
Order of execution –
tc3 – tc2 – tc1 – tc5 – tc4
Let’s see the code implementation:
import org.testng.annotations.Test;public class testNGPr {@Test(priority=-12)public void test1(){System.out.println("test1: priority -12");}@Test(priority=-2)public void test2(){System.out.println("test2: priority -2");}@Test(priority=3)public void test3(){System.out.println("test3: priority 3");}@Test(priority=2)public void test4(){System.out.println("test4: priority 2");}@Test(priority=0)public void test5(){System.out.println("test5: priority 0");}@Testpublic void test6(){System.out.println("test6: test231 no priority");}@Testpublic void test7(){System.out.println("test7: test2311 no priority");}}
OutPut –
test1: priority -12
test2: priority -2
test5: priority 0
test6: test231 no priority
test7: test2311 no priority
test4: priority 2
test3: priority 3As you can see above result, the execution order is as follows –
negative priority – with ‘-1’ being lowest priority (-1 executes last in all -ve priority list)
priority with 0 or no priority set (executes in alphanumerical order for priority 0 or no priority)
positive priority – with 1 being highest proirity (1 executes first in all +ve priority list)
