What is the difference between hard assertion, soft assertion, and verify in TestNG?

As an experienced tutor registered on UrbanPro.com, I understand the significance of mastering assertion techniques in automation testing. Let's delve into the differences between hard assertion, soft assertion, and verify in TestNG to elevate your understanding of effective test validation.

Introduction:

In the realm of automation testing coaching, understanding assertion techniques is fundamental for robust and reliable test scripts. TestNG offers multiple approaches, each serving specific purposes.

1. Hard Assertion:

• Definition:
  • A hard assertion is an assertion that immediately stops the execution of the test case upon failure.
• Usage:
  • Ideal for scenarios where the subsequent steps in a test are dependent on the success of the previous ones.
• Example:
  java

• Assert.assertEquals(actual, expected, "Assertion failed: Actual and Expected values do not match");

2. Soft Assertion:

• Definition:
  • A soft assertion allows the entire test case to continue even after encountering a failure. It accumulates all failures and reports them at the end.
• Usage:
  • Useful when you want to execute multiple assertions within a single test case without stopping the test on the first failure.
• Example:
  java

• SoftAssert softAssert = new SoftAssert(); softAssert.assertEquals(actual1, expected1, "Assertion 1 failed"); softAssert.assertEquals(actual2, expected2, "Assertion 2 failed"); softAssert.assertAll(); // Reports all failures

3. Verify in TestNG:

• Definition:
  • Verify is not an explicit assertion in TestNG; however, it is commonly used in TestNG listeners to perform actions based on the success or failure of a test.
• Usage:
  • Employed in scenarios where you want to execute additional actions or log information based on the assertion result.
• Example:
  java
