Frequently Asked Questions
Common questions about our performance testing services.
Do you provide load and stress testing services?
Yes. AssertQA provides load, stress, and scalability testing services that simulate real traffic so you know exactly how your application behaves under pressure before your users do.
Which performance testing tools do you use?
We primarily use k6.io for performance testing, building realistic load scenarios that integrate cleanly into modern development and CI/CD workflows.
How do you identify performance bottlenecks?
We measure response times, throughput, and resource usage under load, then pinpoint the slow queries, endpoints, and infrastructure limits that cause bottlenecks and recommend concrete fixes.
Can you test whether our application scales before a major launch?
Absolutely. We run scalability tests that model peak launch traffic so you can confidently handle spikes, sales events, or marketing campaigns without downtime.
Do you integrate performance tests into our CI/CD pipeline?
Yes. We can automate performance tests inside your CI/CD pipeline so performance regressions are caught continuously, not just before release.
Do you use AI in your performance testing work?
Yes, we use AI as much as it genuinely helps, for example to spot anomalies in load results faster. But AI doesn't do the work for us. Our engineers design the scenarios and interpret every result.
What Our Clients Say
CEOs, CTOs and QA leads on what changed after our team joined theirs.
AssertQA has been a great partner throughout our mobile automation journey. They helped us navigate the initial challenges, provided practical solutions when we were blocked, and played an important role in getting us started successfully.
AssertQA worked closely with our internal QA team to strengthen their skills in mobile testing and test automation. Their consultants were professional, clear in communication, and genuinely invested in our team's growth.
We brought AssertQA in on several projects to strengthen our QA process, and their team fit right into our workflow. They handled hard manual testing on the trickier parts of the product, plus automation that took a lot of the repetitive work off our plate before releases.
Working with AssertQA has always felt less like working with an external QA provider and more like having an experienced quality partner within the team. The AssertQA team understands both the product and the development process.
Performance testing conducted by the AssertQA team using the k6 tool gave us complete visibility and understanding of the stability of SportTime's existing web platform. By precisely identifying bottlenecks before traffic spikes, we ensured a better user experience and fast site response even under the heaviest loads.
We've been relying on AssertQA's manual testing services at dizmo AG for over five years—initially for our desktop product, and later for our SaaS resource planning platform, Planisy. AssertQA has proven to be a dependable and proactive partner, consistently going the extra mile.
We were rolling out our solution for a client and brought in AssertQA to help with test automation. From day one, they were hands-on, professional, and really cared about making sure everything worked perfectly.
AssertQA has provided us with a range of services across multiple projects we've worked on together. Their automation capabilities are outstanding and integrate quickly into the development team, improving the team's overall efficiency and making the product more robust.
I had the pleasure of collaborating with the AssertQA team on the Efinity project. What sets Tatjana and her team apart is their combination of expertise, dedication, and a professional approach to every task.
We've been partnering with AssertQA since 2023, and the impact on our product quality has been substantial. Their QA team has become an integral part of our development process, catching issues early and helping us maintain the reliability our clients expect from a financial services platform.
