TestNG Assertions in Selenium Java – Hard vs Soft Assertions (assertEquals, assertTrue)

By Bhau Automation • Learn Hard & Soft Assertions in TestNG with Selenium

🎯 What You Will Learn in This Video

• What are assertions in TestNG?
• Difference between Hard Assertion and Soft Assertion
• How to use assertEquals, assertTrue, assertFalse
• Practical Selenium examples with TestNG assertions
• Common mistakes and best practices
• Interview questions on TestNG assertions

💡 Pro Tip: Use Hard Assertions for critical validations and Soft Assertions when you want to collect multiple failures in a single test run.

📌 What are Assertions in TestNG?

Assertions in TestNG are used to validate expected vs actual results during Selenium test execution. If an assertion fails, TestNG marks the test as failed.

❌ Hard Assertion

Hard Assertion stops test execution immediately when an assertion fails.

Assert.assertEquals(actual, expected);
Assert.assertTrue(condition);
  

✅ Soft Assertion

Soft Assertion allows test execution to continue even after assertion failures. All failures are reported at the end using assertAll().

SoftAssert softAssert = new SoftAssert();
softAssert.assertEquals(actual, expected);
softAssert.assertTrue(condition);
softAssert.assertAll();
  

🧪 Commonly Used TestNG Assertions

• assertEquals(actual, expected) – Validates equality
• assertEquals(actual, expected, message) – With custom failure message
• assertTrue(condition) – Validates true condition
• assertTrue(condition, message) – With message
• assertFalse(condition) – Validates false condition
• assertFalse(condition, message) – With message

💻 Practical Selenium Example with Assertions

@Test
public void loginTest() {
    String actualTitle = driver.getTitle();
    String expectedTitle = "Dashboard";

    Assert.assertEquals(actualTitle, expectedTitle, "Title mismatch!");
}
