Every user journey on a website starts from a signup page. Signup page is one of the simplest yet one of the most important page of the website. People do everything in their control to increase the conversions on their website by changing signup pages, modifying them, performing A/B testing to find out the best pages and what not. But the major problem that went unnoticed or is usually underrated is testing the signup page. If you try all the possible hacks but fail to test it properly you’re missing on a big thing. Because if users are facing problem while signing up they leave your website and will never come back.
For your convenience, we have also compiled different types of test case templates.
Testers and QA have a huge challenge while testing a signup page because of the varied possibilities around testing it. Many times, the process works fine on one browser but fails on the other. Cross browser compatibility plays a major role here. So, there needs to be followed a proper testing template to make sure you cover all the aspects of testing a signup page.
We have decided to make the task easier for everyone out there. If you follow all the testing instructions, you can be sure that your signup page is working fine across all browser, operating systems, and devices. We have also added a template at the bottom of the blog page. You can download that free and use it for testing your signup page.
So before moving with the test cases, we need to gather some requirements like:
The fields may also vary according to your registration process. I have tried to cover the maximum possibilities for a sign up page.
The major challenge you’ll face here is to test all possible scenarios for all the possible combinations of browsers, devices, and OSes. Because as we know that the sign up process makes use of APIsand API compatibility in browsers needs to be taken care of. So many times, you’ll find that your sign up is working on a browser but when a user tries to do the same from any other browser or device it will fail.
If a signup page uses strong authentication techniques like second-factor authentication utilizing text SMS verification(or without that), password-less authentication, or encrypted public key then there might be a possibility of cross browser compatibility issues in authentication. Because these techniques make use APIs like web authentication API . The problem that occurs here is that these APIs are unsupported in various browsers.

So authentication will fail on browsers like: IE, older edge versions, older chrome and firefox versions, Safari, iOS Safari, Opera Mini, UC Browser, and Samsung internet. So, if a user tries to signup using these browser, he’ll not be able to finish it off. So, you need to test for these browsers and make sure that the authentication works on all browsers.
There are many websites that ask for payment details or card validation details on signup. So, the registration or sign up may fail if the payment is not processed successfully or the card is not validated.
Developers make use of APIs like Payment Request API for allowing web pages to switch information from the user agent. This is basically done when the user agent provides input before it approves or denies a payment request. This API again comes with some incompatibility issues.

So, you need to test the payment process for all browsers.
While designing a signup page, we make sure of creating a beautiful design by adding some beautiful animations on the buttons for signup. However sometimes this might cause a huge problem.
APIs like Web Animations API that allow you to synchronize and change timings of a web page (animations of DOM elements), sometimes cause compatibility issues in browsers.

As you can see, APIs holds a major portion of compatibility issues in a signup process. So it’s important to test APIs and overall page functionalities as well for a signup page along with the mentioned test cases for a signup process on all browsers and browser versions. TestMu AI platform can help you in making sure that your page is compatible across all browsers.

You can also use this test case template for maintaining your test results for a signup page. Download it free and use this as a standard template.
When it comes to , you can verify all the above test results across all browsers one by one.
