Registration and sign-up pages are a key part of any application or website, and are very important, as they serve as the entry point for users to access the features and services of the product. It is critical to ensure that registration pages work thoroughly and reliably; Poorly tested registration pages can result in lost user data, failed registration attempts, or even security breaches due to overlooked vulnerabilities. Every second of the user experience is critical, especially when so much in a digital e-commerce world, he needs to ensure content is processed, allowing the user to move through the registration process seamlessly.
To ensure a thorough registration process, comprehensive testing is very important. This includes testing a combination of inputs, validation checks, security, and a specific user flow under specific conditions, or goals. Test cases ensure the functionality of the registration page, covering basic field validations, advanced security testing (such as SQL injection prevention), and performance testing under different load conditions.
In this blog, we will outline important test cases and general test scenarios and topics to be considered for registration and sign-up pages. The examples on the blog are suggestions for designers to recreate a certain set of graphic elements and entail ideas to automate the test cases explored.
Common fields in the Registration Page
Every registration page usually includes a few common fields that are required in order to gather specific data about the user, create an account for them, and allow access to a service. The registration form fields will allow you to identify users, validate contact information, and generate login details from them. The exact framing or layout may differ depending on the application, but the important components usually will not change significantly. Here’s an example of common fields, illustrated using TestGrid’s registration page (shown below):

1. Full Name: The full name’s field allows for the capture of the user’s first and last name; this allows for an account to be created to link to an actual person for future communication and transactional interactions.
2. Business Email: This field is critical for account verification and communication. It requires the user to enter a valid email address.
3. Mobile Number: Many sites require a mobile number for two-factor authentication (2FA), which ensures additional verification through mechanisms such as OTP (One-Time Password).
4. Password: Passwords are essential for user security. Strong password rules help reduce the risk of unauthorized access.
5. Sign-Up Button: The final step in the registration process is the submission of the form via a “Sign Up” button.

Functional & Non-Functional Test Cases for a Registration Page
A registration page includes multiple functional and non-functional aspects that require thorough testing. Below is a list of test cases for registration page for both functional and non-functional requirements. It covers a range of scenarios, including positive and negative cases, security tests, and UI test cases.
Functional Test Cases
Functional test cases would ensure that every element of the registration page works according to the requirements and user’s expectations. These test cases will most likely test on inputs, form submission, and validation logic.
1. Field Validation
- Test Case 1: Validate that each mandatory field (for example, Full Name, Email, Password) displays proper error messages when left blank.
- Test Case 2: Confirm the email field accepts only usernames in the valid email format (e.g., username@domain.com) and is always unique.
- Test Case 3: Verify password field must be of adequate strength, commonly having at least 8 characters with mixed case letters, digits, and special characters.
- Test Case 4: Verify that the mobile number field accepts only the number type of input along with restrictions like minimum/maximum length and validation based on country code.
- Test Case 5: Verify an error message for an invalid input is clear and near the relevant field.
2. Field Input Boundaries
- Test Case 6: Validate that fields like Full Name do not allow special characters and digits.
- Test Case 7: Verify that fields such as Full Name, Password, and Mobile Number enforce minimum and maximum character limits.
- Test Case 8: Verify that fields like Mobile Number do not accept a combination of alphanumeric.
- Test Case 9: Verify that leading and trailing blank spaces are trimmed in the input fields while submitting the form.
3. Form Submission
- Test Case 10: In case, all the required fields are not filled with valid information the form will not be accepted.
- Test Case 11: If all the fields get filled with valid details, it results in the user’s successful registration.
- Test Case 12: Check whether the mail/message is sent as an activation mail or message after successful registration.
- Test Case 13: Ensure that duplicate email addresses cannot be used to register multiple accounts.
- Test Case 14: Test if the form resubmission after page refresh results in any errors.
4. Security & Authentication
- Test Case 15: Ensure that sensitive fields (e.g., Password) mask the input characters.
- Test Case 16: The password fields must conform to security requirements (for example, strength, and hashing over the wire).
- Test Case 17: Test the CAPTCHA or other anti-bot control such that there are no automated registrations.
- Test Case 18: Ensure the system prevents SQL injection attacks and generates appropriate error messages when malicious input is detected.
5. Input Format and Data Integrity
- Test Case 19: Verify that the email field should not accept special characters before @.
- Test Case 20: Ensure that the date of birth (if applicable) does not allow future dates.
Non-Functional Test Cases
Non-functional test cases are those that focus on features like performance, usability, and security that make the registration process user-friendly and robust.
1. Performance Testing
- Test Case 21: The registration form should load within an acceptable time frame (e.g. less than 3 seconds).
- Test Case 22: Form submission response time should be within the accepted threshold even with a heavy user load.
- Test Case 23: Test system behavior with the registration of many concurrent users.
2. Usability Testing
- Test Case 24: The look of the registration form should be user-friendly and intuitive that must be easy for the user to complete.
- Test Case 25: Error messages should be clear, informative, and placed appropriately on the screen.
- Test Case 26: Ensure the form is fully accessible, compatible with screen readers, and navigable using only the keyboard, in compliance with WCAG (Web Content Accessibility Guidelines).
- Test Case 27: Test if the form is responsive and friendly in various mobile devices and sizes.
3. Security Testing
- Test Case 28: Validate that sensitive data (e.g., password) is encrypted during transmission.
- Test Case 29: Determine if there are points that can be easily attacked by hackers, which access unauthorized access in registration bypassing without validation)
- Test Case 30: Test against Cross-Site Scripting (XSS) attacks by entering malicious scripts in input fields.
4. Compatibility Testing
- Test Case 31: Verify that the registration form works seamlessly across different browsers (Chrome, Firefox, Safari, etc.).
- Test Case 32: This form must be checked by seeing its behavior when it is opened on different operating systems, like Windows, Mac Os, Android, iOS etc
5. Scalability Testing
- Test Case 33: Test the system’s scalability by increasing the number of simultaneous registrations. Ensure the system can handle the load without performance issues or failure.
6. Reliability Testing
- Test Case 34: Verify the registration system remains stable and does not hang or crash during normal operation.
- Test Case 35: Verify whether, in case of system failure during a mid-submission form, the registration data are recovered correctly.
Factors to consider when writing test cases for registration page
Writing test cases for a registration page is appropriate only when it has been well-thought-out to consider all potential problems and thus, ensuring complete and secure navigation by the user. Major considerations are as follows:
1. Input Validation:
Validate the input fields. This would be an important thing to test and verify whether the sign-up form can accept the correct data format – valid email formats, numeric-only phone numbers, and secure passwords. This involves testing boundary conditions including minimum and maximum lengths for fields.
2. User Experience:
A frictionless flow of registration should be assured by using user-friendly error messages and forms. Test cases will determine whether the error message is clear, informative, and properly placed so that the user can correct the mistake quickly. The responsive form on both desktops and mobile phones also needs to be tested.
3. Security:
Security must be the priority of any registration process. The password should be encrypted, and email addresses or phone numbers should not be exposed in the process. Also, testing against common vulnerabilities like SQL injection and cross-site scripting (XSS) is very important.
4. Performance:
Test the registration form under different load conditions to ensure the system performs well even under heavy traffic. Test cases should simulate scenarios where many users attempt to register simultaneously.
5. Compatibility:
Last, but not the least, test cases could be based on how the registration form works in all types of browsers, operating systems, and different devices so that the user has no problem accessing the page regardless of how he does it.
