TestNG Parallel Execution

• Methods: This will run the parallel tests on all @Test methods in TestNG.
• Tests: All the test cases present inside the <test> tag will run with this value.
• Classes: All the test cases present inside the classes that exist in the XML will run in parallel.

package com.parallel;
import org.testng.annotations.Test;

public class TestParallelOne {

    @Test
    public void testCaseOne() {
        //Printing Id of the thread on using which test method got executed
        System.out.println("Test Case One with Thread Id:- "
                + Thread.currentThread().getId());
    }

    @Test
    public void testCaseTwo() {
        ////Printing Id of the thread on using which test method got executed
        System.out.println("Test Case two with Thread Id:- "
                + Thread.currentThread().getId());
    }
