I suggest you to use soft assertions, which are provided in TestNg natively
package automation.tests;
import org.testng.asserts.Assertion;
import org.testng.asserts.SoftAssert;
public class MyTest {
private Assertion hardAssert = new Assertion();
private SoftAssert softAssert = new SoftAssert();
}
@Test
public void testForSoftAssertionFailure() {
softAssert.assertTrue(false);
softAssert.assertEquals(1, 2);
softAssert.assertAll();
}
