In today's digital world, it's essential to ensure that your applications can handle real-world workloads. Load testing simulates typical and peak loads to evaluate performance and scalability, while stress testing pushes systems to their limits to uncover vulnerabilities and weaknesses. These types of performance testing are vital for delivering reliable, high-performing digital solutions. Since 2010, DeviQA has been catering to a wide range of industries, including Healthcare, FinTech, Real Estate, Cybersecurity, Retail, AdTech, and more. Leveraging our deep expertise, we create robust solutions for performance testing, including stress and load testing, that thoroughly assess your software and deliver accurate results.

Our Scope of Load and Stress Testing Services

We prioritize delivering high-quality testing services that empower you to release software with confidence. Our expert team is committed to ensuring your digital solutions perform optimally, meeting the expectations of your users and the requirements of your business.

Load Testing

We simulate real-world scenarios, assessing how well your system can manage increased user loads. Identify bottlenecks and optimize your software to ensure a smooth user experience during peak usage periods.

Capacity Testing

We analyze your application's capacity limits and determine the maximum number of users, transactions, or data volumes it can support. Prepare your digital assets for future expansion without sacrificing performance.

Stress Testing

We simulate challenging scenarios, pushing your system to its limits to identify potential failure points. By uncovering weaknesses, we help you fortify your software, ensuring it remains reliable even in the face of unexpected stressors.

Soak Testing

We assess the stability and performance of your application under prolonged usage. Identify memory leaks, performance degradation, or other issues that may arise during extended operation, allowing you to address them before they impact your users.

Elevate your software quality with our cutting-edge QA solutions.

Don’t let software bugs and performance issues jeopardize your reputation.

Choose Your Cooperation Model

We understand that every project has its own unique requirements and challenges. That's why we offer three flexible cooperation models, letting you choose the option that suits your needs best.

Staff Augmentation

If your in-house team has a knowledge gap in load and stress testing, our experts can seamlessly integrate into your workflow, providing the support and expertise you need to succeed.

  • Best Option for: Projects with fluctuating load and stress testing needs and projects where specific load testing skills are required on a temporary basis.

  • Immediate access to experts in load and stress testing.

  • Greater flexibility in resource allocation and project management, allowing you to adapt to changing testing requirements and priorities.

  • Significant cost-effectiveness, compared to hiring full-time employees.

Dedicated Team

A dedicated QA team works exclusively on your project and under your guidance to help you achieve your QA goals.

  • Best Option for: Projects with complex architectures or strict performance requirements that necessitate ongoing load testing and performance optimization.

  • High level of commitment and focus on your load testing requirements.

  • Direct communication with team members and real-time feedback.

  • Flexibility to scale the team up or down based on project demands and timelines.

Get started


Our experienced team leverages industry-leading tools and methodologies to simulate realistic user loads, identify performance bottlenecks, and provide actionable recommendations for optimization.

  • Best Option for: Projects with limited internal expertise in load and stress testing or those that need an independent assessment of their software performance.

  • Cost-effective approach that lets you reduce testing costs.

  • Access to a diverse talent pool of professionals in load and stress testing.

  • Shorter testing timelines and time-to-market for your applications.

Our Approach to Load and Stress Testing

We take a comprehensive and systematic approach to load and stress software testing to ensure that your systems can withstand heavy user loads and maintain optimal performance under various conditions.

Understanding Your System

We begin by gaining a deep understanding of your software architecture, technology stack, user requirements, and expected usage patterns. This allows us to simulate realistic scenarios and identify potential performance bottlenecks.

Developing Customized Test Scenarios

Based on our understanding of your system, we develop customized test scenarios that mimic real-world user behavior, traffic patterns, and load levels. These scenarios are designed to stress-test your system and uncover any performance issues under different conditions.

Utilizing Advanced Testing Tools and Techniques

We leverage state-of-the-art load testing tools and techniques to conduct rigorous testing of your software. Our team has expertise in using industry-leading tools that simulate thousands of concurrent users, measure system response times, analyze resource utilization, and identify performance bottlenecks.

Scaling Testing Environments

We ensure that our testing environments are properly scaled to replicate production conditions as closely as possible. This includes provisioning sufficient hardware resources, configuring network settings, and replicating the software stack to accurately simulate the production environment.

Analyzing Performance Metrics

Throughout the testing process, we collect and analyze a wide range of performance metrics, including response times, throughput, error rates, and system resource utilization. These metrics provide valuable insights into the performance and scalability of your software, allowing us to identify areas for optimization and improvement.

Providing Actionable Insights and Recommendations

Upon completion of load testing, we provide comprehensive reports detailing our findings, observations, and recommendations. Our reports include actionable insights and recommendations for optimizing system performance, enhancing scalability, and improving the overall user experience.

Continuous Monitoring and Iterative Testing

We believe in the importance of continuous monitoring and iterative testing to ensure ongoing performance optimization. Our team works closely with you to implement monitoring solutions and conduct periodic load and stress testing to proactively identify and address any performance issues as your software evolves.

Dev capacity:



Didn’t have a formal QA process

Built smooth and well-working processes

Didn’t make automated testing

Test automation : smoke, API, UI on all supported browsers

Testing was carried out by the devs

Test coverage :



Existing workflow in Jira didn’t allow to understand how many bugs were left unfixed before the release and their priorities

Adjusted the Jira workflow, integrated TestRail with Jira to be able to see statisticls of the issues per release

The lack of test documentation

Developed necessary test artifacts that adhere to industry standards and are easily maintainable

No Automation test coverage

Added multithreading to run tests in parallel on 10 different threads, which reduced the time of the test run in 7 times
