Test Case Scenario For Login Page

How To Articles

As a software tester, one of the key responsibilities is to ensure that the login page of an application functions properly and securely. In this article, I will walk you through a test case scenario for a login page, providing personal touches and commentary from my experience.

When testing a login page, the first step is to verify that the page is displayed correctly and all the necessary elements are present. This includes the login form, username field, password field, and a login button. It’s important to pay attention to the design and layout of the page, as it contributes to the overall user experience.

Next, I would focus on testing the functionality of the login page. This involves testing various scenarios, such as:

1. Valid Credentials

In this scenario, I would enter a valid username and password combination and click on the login button. The expected result would be a successful login, redirecting the user to the application’s homepage. I would personally feel a sense of accomplishment when the login is successful, as it indicates that the login page is functioning as expected.

2. Invalid Credentials

Here, I would intentionally enter incorrect or invalid credentials and click on the login button. The expected result would be an error message indicating that the login failed due to invalid credentials. This test is crucial to ensure that the login page properly handles incorrect inputs and provides appropriate feedback to the user.

3. Forgot Password Functionality

In this scenario, I would test the “Forgot Password” functionality of the login page. I would click on the “Forgot Password” link and enter a registered email address. The expected result would be an email sent to the provided email address with instructions to reset the password. Testing this functionality is important to ensure that users who forget their passwords are able to easily recover their accounts.

4. Account Lockout

This scenario involves testing the account lockout feature of the login page. I would attempt to enter incorrect credentials multiple times, exceeding the maximum allowed attempts. The expected result would be the user account getting locked for a certain period of time. This test is important to prevent brute force attacks and protect user accounts from unauthorized access.

5. Cross-Site Scripting (XSS) Attacks

As part of security testing, it’s crucial to check if the login page is vulnerable to Cross-Site Scripting (XSS) attacks. I would try entering malicious scripts or HTML code into the username or password fields and check if the application properly sanitizes the input, preventing any potential security breaches.

Throughout the testing process, it’s important to take detailed notes and document any issues or bugs encountered. This documentation will help the development team fix the issues and improve the overall quality of the application.


The login page of an application is a critical component that requires thorough testing to ensure its functionality and security. By following the test case scenario outlined in this article, you can be confident in the reliability of your application’s login page. Remember to pay attention to both functional and security aspects, and always document your findings.
