Scalability Testing Services

Your project runs well now, but will it hold up when it’s used by millions of users? Our experienced QA engineers will ensure that it can handle user requests at any scale!


Scalability testing will help you make sure that your software is fully set up for the future growth of your business. Is your software ready for large surges of new users? Will your servers be able to handle increased traffic? Will your software continue to be reliable when your systems are stressed? Thorough scalability tests can bolster your confidence in the long-term success of your business.

Scalability testing is non-functional testing that evaluates your software, application, or website performance under load. This can include load testing, performance testing, smoke testing, etc. Features like your software’s response time, throughput, memory usage, and request limits are put to the test. This will let you know the limits of your current build as well as provide you with valuable insights and blueprints for future development.

TestFort’s QA engineers have been providing scalability testing services for startups and enterprise businesses alike, ensuring our client’s software is fully prepared for the ambitious plans of key stakeholders. Our engineers are able to start testing quickly and provide consistent results that your business can count on.

  • Future-proofing Your Software
    Scalability testing allows you to understand how much “headroom” your software has before it meets its limit. This will allow you to create a long-term development strategy for your product and make the right choice between expanding your functionality or building the foundation for future growth.
  • User Satisfaction
    The growth of your business will mean that more users will engage with your software. If your client base grows — you’re doing something right! Scalability testing will help you ensure that your loyal clients' expectations are still being met when thousands of new users discover your software.
  • Cut Costs
    Conducting scalability testing on your software will help you make sure your developers have built a solid foundation for your project’s future growth. This means that when the time comes, you can be confident that all you’ll need to do to scale your solution is add a few more data centers and servers instead of needing to rebuild your solution from scratch.
  • Proactive Response
    Scalability tests will allow you to be proactive in your project’s development, focusing on long-term ambitions instead of limiting yourself to your current opportunities.

    We have worked on hundreds of projects. We’ve worked with startups and enterprise clients. We’ve seen small projects explode in popularity and large enterprise suites easily handle corporate mergers. We know how to ensure the scalability of our clients' software.

    Different businesses require different development approaches. Whether your team runs daily stands, is dedicated to lean development, or prefers agile workflows — our QA engineers will adapt to your routines and processes.

    Our teams are just as scalable as your software will be. When your project grows, TestFort will have additional software testers and QA engineers ready to join your team when they are needed most.
