How to Write Test Cases for Registration Page?

A registration page of any website consists of multiple fields, such as username, password, email address, first and last name, and a few more to allow users to sign up. Writing test cases for the registration page includes checking the functions of all these input fields with positive and negative values.

Let’s see how you can design, develop, and execute the test cases to validate the registration page of your website.

Possible List of Functional & Non-Functional Test Cases for a Registration Page

Any registration page has several functional and non-functional features that need to be tested. Below are the functional & non-functional test cases for a registration page for you to consider. This list comprises a variety of test scenarios for the registration page, including both positive and negative cases, various security test cases, and UI test cases.

Functional Test Cases

• Verify that all mandatory fields are marked as such and cannot be left blank.
• Validate that the registration form accepts valid and unique email addresses.
• Test if the password field contains a requirement for minimum input length.

Test Cases for Registration Page: Another Approach

Here we take a slightly different approach of creating the test cases, they are created according to the many fields on the registration page: First name, Last name, email address, local phone number, Username, Password, Terms and conditions checkbox, and a captcha.

Feature to be Tested	Test Cases
First name	1. Check if the first name is mandatory.  2. Check if the first name field uses only alphabets.  3. Test if the field shows error message for numbers and special characters entry.  4. Check if the field shows an error message when left blank.
Last name	1. Check if the last name is mandatory.  2. Check if the last name field uses only alphabets.  3. Test if the field shows error message for numbers and special characters entry.  4. Check if the field shows an error message when left blank.
Email address	1. Check for valid email address format.  2. Check for invalid email address format.  3. Test if the email address shows an error message when left blank.  4. Check if the field is case sensitive.  5. Test the field with leading/trailing spaces and for its maximum length.  6. See if the email address is duplicate/already existing in the database.
Phone number	1. Check for valid/invalid phone number.  2. Test the field with leading/trailing spaces and for its maximum length.  3. See if the phone number is duplicate/already existing in the database.  4. Test if the email address shows an error message when left blank.  5. Check if the last name field allows numbers only.  6. See if the phone number field shows an error message for alphabets and special characters entry.
Username	1. Check for existing and valid usernames.  2. Check for invalid usernames with wrong characters, such as #, $, and -.  3. Test the field for case sensitivity and maximum length of the input characters.  4. See if the field allows alphanumeric input as per user specifications.  5. Check if an error message is shown for using an existing username.  6. Verify if the system trims the whitespace and accepts the username.
Password	1. The password should be a minimum and maximum characters long.  2. The password should have at least 1 uppercase and 1 lowercase letter.  3. Password should consist of at least 1 number.  4. The field must have at least 1 special character.  5. The password should not be the same as the username.  6. Test if the input in the password matches with the confirm password fields.  7. Check that error messages are shown for blank password field.
Terms & Conditions	1. Test that the terms and conditions have a checkbox for users to click.  2. Test if the terms and conditions are clear in giving the right information.  3. The user should be able to register only when the terms and conditions checkbox is clicked.  4. Test if the page displays a confirmation message after ticking the checkbox and completing the registration.  5. Ensure that the terms and conditions are clearly displayed and visible on the registration page.  6. See if users can uncheck the box after checking it.  7. Test if the checkbox is accessible easily.

Factors to Consider When Writing Test Cases for Registration

When writing test cases for a registration page, there are several factors you should consider to ensure thorough testing and comprehensive coverage.

• What are the text fields that need to be tested? Read more – How Do You Write Test Cases for a Text Box?
• Functionalities pertaining to every field needs to be tested.
• What would happen if an existing user tries to register with the same details?
• Proper error handling in cases such as invalid input, wrong captcha, non-existing email IDs, and blank fields.
• Consider if special characters are allowed in the input fields, along with seeing that name and number should show an error when entered with special characters.
• What should be the response of the page when a vast number of users click to register simultaneously?
• Should the input fields have a specified length for the entry? And if this criterion is not fulfilled, what message should the page display?

How to Create Test Cases for Registration Page?

You know what test cases to develop for the registration page. Now learn how you can create those test cases efficiently so they cover the maximum testing area with high output.

Define and Understand the Requirements

Before designing and writing the test cases, you need to understand what features of the registration need to be tested and how they behave. Only after that can you properly develop the tests and compare the results to see if the fields on the page are working as expected.

Check for Positive and Negative Inputs

Whenever you are writing the tests, ensure to include both positive and negative scenarios. This will help you to cover all the possible cases users may enter details into the registration page fields. Some examples are testing fields by keeping them blank and using special characters.

Test Performance

See if the features of the registration page are properly loading and visible when the page receives multiple hits simultaneously. When the page is made live on the website, it is likely that hundreds of users will hit the registration at one given time. The page should load and allow all of them to register without any glitches.

Give Attention to Important Pop-Ups and Messages

Pay attention to error messages, tooltip information, and terms & conditions closely to make sure that those important instructions do not contain wrong or misleading information. They might seem negligible when seen from the viewpoint of developers and testers, but they hold high value when users are trying to understand the registration process.
