Asserting in TestNG Understanding TestNG Assertions Assertions in TestNG are essential for validating expected outcomes during test execution. Here's how you can assert in TestNG: TestNG's Assert Class Import Assert Class: To use assertions in TestNG, start by importing the Assert class from the TestNG framework. java import org.testng.Assert; Assert Methods: TestNG provides various assert methods within the Assert class for different types of validations, such as assertEquals, assertTrue, assertFalse, and more. Common Assert Methods assertEquals: Verifies if two values are equal. java Assert.assertEquals(actual, expected, "Assertion message for failure"); assertTrue and assertFalse: Checks if a given condition is true or false. java Assert.assertTrue(condition, "Assertion message for failure"); Assert.assertFalse(condition, "Assertion message for failure"); assertNull and assertNotNull: Validates if a value is null or not null. java Assert.assertNull(value, "Assertion message for failure"); Assert.assertNotNull(value, "Assertion message for failure"); assertSame and assertNotSame: Ensures that two objects refer to the same or different objects in memory. java Assert.assertSame(actual, expected, "Assertion message for failure"); Assert.assertNotSame(actual, expected, "Assertion message for failure"); Practical Example Consider a simple example: java import org.testng.Assert; import org.testng.annotations.Test; public class SampleTest { @Test public void testExample() { String actualValue = "Hello"; String expectedValue = "Hello"; // Using assertEquals Assert.assertEquals(actualValue, expectedValue, "Values are not equal"); // Using assertTrue Assert.assertTrue(actualValue.contains("lo"), "Substring not found"); } } In this example, assertEquals checks if two strings are equal, and assertTrue verifies if a substring is present in the actual value.
