Test Case ID | Description | Expected Results |
TC002 | Enter the incorrect username and password | Access is denied with an error message |
Test Case for Incorrect Password
When you enter the incorrect password using the correct username should block the access and prompt an error message.
Test Case ID | Description | Expected Results |
TC003 | Enter the correct username and incorrect password | Access is denied with an error message |
SQL Injection Test
This is a crucial security test, SQL injection testing helps in checking if the login pages it is vulnerable to injection attacks.
Test Case ID | Description | Expected Results |
TC004 | Enter the SQL command in the username/password field | The systems should prevent the database access |
Cross-Site Scripting(XSS) Attack Prevention
Cross-site scripting (XSS) attacks can cause severe security breaches. The test case helps in ensuring that the login page is XSS-proof
Test Case | Description | Expected Results |
TC005 | Inject the Javascript in the username/ password fields | The system should prevent system execution |

Additional Functional Test Case
Beyond security, the login pages should be user-friendly and free of any errors. Below are some additional test cases that are focused on functionality and usability.
Empty usernames and password fields
Testing the login process with both the fields empty and ensuring that the system prompts users to enter credentials
Test Case | Description | Expected Results |
TC006 | Leave the username and password field empty | The system prompts “Please enter the credentials” |
Password Masking Test
It is done for the security of the user, the passwords must be masked to avoid the risk associated with shoulder surfing
Test Case ID | Description | Expected Results |
TC007 | Check whether the password is masked | The password should be hidden as ******** |
“Remember Me” Checkbox Functionality
A lot of login pages offer a “Remember me” option. Test cases check whether the test functions as expected
Test Case ID | Description | Expected Results |
TC008 | Check the “Remember me” functionality | The users remain logged in for a specific duration |

Test Case ID | Description | Expected Results |
TC009 | Measure the loading speed of the page | Login page loads within 2-3 seconds |
Timeout and Auto-Logout
It is used to protect against unauthorized access with many sessions having session timeouts. The test case helps by verifying that the session expires after inactivity.
Test Case ID | Description | Expected Results |
TC010 | Check the session timeouts after 10 minutes | Users log out after 10 minutes of inactivity |
Security Statistics You Should Consider?
- More than 75% of the data breaches happen due to stolen or weak passwords
- More than 60% of the cyberattacks are caused on login pages and user access points
- More than 90% of the users abandon the website due to its poor functionality
Best Practises Used for Login Pages
- Use of Automation Testing: It helps you by speeding up the process and improving the accuracy with the help of automation tools
