The login page is one of the most important parts of any application. Rigorously testing the login functionality from the start helps ensure a smooth user experience. When writing test cases for the login page, there are some key techniques you should keep in mind. Follow these tips to create effective test cases for login page works properly and handles errors gracefully.
Well-designed test cases are essential for catching issues with the login process before launch. Testing this critical workflow early prevents defects from reaching users and compromises their first impression of your application. Structuring your test cases for the login page thoughtfully will help you achieve comprehensive coverage.
- Validate normal login flows
Start by testing the happy paths with valid credentials. Write test cases to verify successful logins for the different valid user types supported. For example, test logins for standard users, administrators, and any other applicable roles. Ensure password masking, case sensitivity, and encryption are handled properly.
- Test field validations
Next, construct test cases to confirm input validations on the username and password fields are functioning. Try submitting the form with missing credentials, incorrect data types, and invalid lengths to trigger validation errors. Verify the appropriate error messages displayed to guide the user.
- Simulate common user errors
Users will inevitably encounter mistakes during login, so build test cases simulating common errors. Test incorrect usernames, invalid passwords, mismatched credentials, and even paste mishaps with example data. Confirm the system responds with clear error messaging and does not expose sensitive account details.
- Check forgot password flow
If your application has a password recovery option, thoroughly test this alternate flow. Validate the “forgot password” link, email input, and reset instructions to operate smoothly. Include test cases for invalid or non-existent email addresses. Testing robust password recovery will prevent headaches for users and your support team.
- Verify persistent login functionality
Modern applications frequently offer persistent login options like “Remember Me.” Construct test cases to confirm these functionalities work across visits. Verify cookies are set properly so users remain logged in when returning to the site or app. Check that persistent sessions expire correctly after the designated time period.
- Examine integration with sign-up
Many applications allow new users to sign up and seamlessly log in. Test cases should verify the integration between these related flows. Sign up for new user accounts and confirm immediate login works properly. Check whether pending email verifications prevent logins as expected.
- Test login page security
It’s crucial to build test cases that validate security measures on the login page. Attempt logins with SQL injection or other hacking techniques in the username and password fields. Verify that these do not grant access and are handled gracefully. Check that repeated failed logins are rate-limited as expected. Confirm the inactive session timeout according to security best practices.
Conclusion
Rigorous test cases focused on the login page will help ensure a positive user experience from the start. Validate normal and erroneous flows, field validations, error handling, password resets, persistent logins, and integration with sign-ups. Keeping these tips in mind as you write test cases for login page will instil confidence in your login process before release. Comprehensive test coverage of this critical workflow pays dividends through smooth onboarding and retention.
