Regression Testing With Real Example of Login Page

Let’s start by writing regression test cases for a login page, and then we’ll add a new feature to the login page and update the regression test cases to include the new feature.

Regression Test Cases for Login Page:

1. TC-01: Verify that the login page is accessible and loads without any errors.
2. TC-02: Validate that all login page elements (username field, password field, login button) are displayed correctly.
3. TC-03: Check if a user can successfully log in with valid credentials.
4. TC-04: Verify that an error message is displayed when attempting to log in with invalid credentials.
5. TC-05: Ensure that the “Forgot Password” link redirects to the correct page.
6. TC-06: Test that the “Create New Account” link redirects to the registration page.
7. TC-07: Verify that the “Remember Me” option persists in the login state after the user logs out and logs back in.
8. TC-08: Test the behavior when the user tries to log in with empty username and password fields.
9. TC-09: Verify that the login page is responsive and displays correctly on different screen sizes.

Now, let’s add a new feature to the login page:

New Feature: Social Media Login Integration
The new feature involves allowing users to log in using their social media accounts, such as Google or Facebook.

Updated Regression Test Cases for Login Page (including the new feature):

1. TC-01: Verify that the login page is accessible and loads without any errors.
2. TC-02: Validate that all login page elements (username field, password field, login button) are displayed correctly.
3. TC-03: Check if a user can successfully log in with valid credentials.
4. TC-04: Verify that an error message is displayed when attempting to log in with invalid credentials.
5. TC-05: Ensure that the “Forgot Password” link redirects to the correct page.
6. TC-06: Test that the “Create New Account” link redirects to the registration page.
7. TC-07: Verify that the “Remember Me” option persists in the login state after the user logs out and logs back in.
8. TC-08: Test the behavior when the user tries to log in with empty username and password fields.
9. TC-09: Verify that the login page is responsive and displays correctly on different screen sizes.
10. TC-10: Verify that the “Login with Google” option is displayed on the login page.
11. TC-11: Check if the user can successfully log in using their Google account.
12. TC-12: Verify that the “Login with Facebook” option is displayed on the login page.
13. TC-13: Check if the user can successfully log in using their Facebook account.
14. TC-14: Test the behavior when a user tries to log in with an unregistered social media account.

Example Scenario to Explain Regression Testing Goal:

Imagine a company’s web application that requires users to log in to access personalized content and features. The login page has been thoroughly tested and is working perfectly. However, the company decides to add a new feature to the login page, allowing users to log in using their Google or Facebook accounts for a more convenient login experience.

During the development and integration of the new feature, the testing team executes the existing regression test cases (TC-01 to TC-09) to ensure that the original functionality of the login page remains intact and unaffected by the changes. This helps confirm that users can still log in using the standard credentials without any issues.

Next, the testing team executes the new test cases (TC-10 to TC-14) specifically designed for the new feature. These test cases aim to verify that the social media login integration works smoothly and users can log in using their Google or Facebook accounts without any errors.

The regression testing goal in this scenario is to ensure that the introduction of the new feature did not introduce any unexpected issues or break the existing functionality of the login page. It helps guarantee that both the original login process and the new social media login feature work harmoniously, providing a seamless experience for users. By performing regression testing after introducing changes, the team can confidently deliver a stable and reliable login page with the added benefit of social media login integration.
