TestNG: Hard Assertions

In testNG, if the hard assertion fails, then the statements after the assertion in given test case will not get executed.

Example

@Test
public void test2() {
 System.out.println("Failing the assertion");
 assertTrue(false);
 System.out.println("I am not executed");
}

In the above example, assertion will be failed, and the information "I am not executed" will not printed to console.

HardAssertDemo.java

package com.sample.app.assertions;

import static org.testng.Assert.assertTrue;

import org.testng.annotations.Test;

public class HardAssertDemo {

 @Test
 public void test1() {
  System.out.println("test1 in execution");
 }

 @Test
 public void test2() {
  System.out.println("Failing the assertion");
  assertTrue(false);
  System.out.println("I am not executed");
 }

 @Test
 public void test3() {
  System.out.println("test3 in execution");
 }

}

Run HardAssertDemo.java, you will get below messages in console.
