Stress testing is a type of performance testing that checks software robustness and stability under extreme load as well as the software ability to recover after a failure.

ScienceSoft usually starts with load testing to define the normal load and check how the system withstands it. Then, we exceed the normal load to see how software behaves in stress conditions.

Star Star Star Star Star

I hired ScienceSoft to perform stress testing of our software. The team at ScienceSoft built a solid platform for stressing out servers, and it helped us uncover a variety of bugs and revisions that needed to built to our code. The team at ScienceSoft is professional and organized in every way possible. I look forward to working with this team again.

We contracted ScienceSoft to provide QA for a major Augmented Reality installation project, after extensive research, and we're really happy with our decision. The team were flexible, thorough and on-the-spot, and able to provide assistance for short-term mission critical testing. We'd happily recommend them to other mobile and immersive developers.

Steps We Follow During Stress Testing










Do We Share the Same Values?


ScienceSoft provides detailed and transparent testing documentation in accordance with ISO/IEC/IEEE 29119-3:2021, making the stress testing reports clear, actionable, and useful for future evolution of the system or further load & stress tests.

Realistic load profiles

We create realistic load profiles, paying attention to user roles and considering all relevant devices, browsers, protocols, and geographical regions. This way, we test your software in life-like conditions and help you ensure all the required functions will work well under extreme load.

Pragmatic approach

Our testing experts opt for effective open-source tools like Apache JMeter and reuse test data from previously simulated scenarios to optimize testing costs and time.

Doubtful about Third-Party Stress Testing? We Address Top 3 Concerns

How can we be sure you’ll dive into the specifics of our software and understand its logic, user roles, and their behavior?

ScienceSoft’s test engineers know how to effectively cooperate with our customers’ IT and business teams to gather all the necessary information and build realistic load profiles. With our solid background in software development and testing for 30+ industries, we are ready to provide specialists that will understand your needs and adapt our testing approach to your software specifics.

Will testing under extreme load be safe for my software and IT infrastructure?

Before testing your software under extreme load, we estimate possible risks and design a risk mitigation plan. We always perform stress testing in a separate test environment and create all the necessary backups to easily roll back to the previous system condition.

Do you have the actual capacity to simulate the behavior of thousands of users?

Holding partnerships with AWS and Microsoft, ScienceSoft sets up a load generator in the cloud environment, which allows us to simulate an infinite number of users.

We Use Only Reliable Tools
