We will test your product from the details to the whole

The use of artificial intelligence in software testing is now a key topic for most enterprise QA teams we work with. Over the past two years, the pace of software delivery has changed significantly: with AI agents, developers are now producing 2–3 times more pull requests and changes to existing code, creating new demands on testing. The business expects more frequent releases, a higher volume of changes, and faster feedback. QA teams therefore need to prioritize more effectively what to test manually, what to automate, and where to focus on the greatest risks. AI agent-powered test automation is becoming even more important in this environment, but it needs to be reliable, maintainable, and built on high-quality data. We can help you tackle this challenge: from risk prioritization and designing reliable test automation to integrating AI agents into everyday testing workflows.

In the world of agile teams, frustrations often arise from errors, increasing costs, and disrupted collaboration. Many teams assume the problem lies in technology, tools, or poorly structured processes. However, the real key to quality is a team’s ability to collaborate effectively and share responsibility for results. Discover how Quality Engineering can transform your team's collaboration and build quality from the start.

We put your leaders first. We offer regular support, a safe space to share experiences and clearly structured processes to simplify their day-to-day decision-making. We help develop leadership, increase team satisfaction and maintain continuity.

Successful implementation of automated testing is becoming more and more business critical. The need to automate is being driven by the growth of digital business, and an increasing adoption of agile development and continuous integration. In these situations tests need to be repeated quickly, to maintain team velocity and to verify that nothing was broken by the latest build. Unfortunately, many attempts to implement test automation fail because of unrealistic expectations, poor strategy and processes, the wrong tools or missing skills. We can help you to avoid these pitfalls.

Manual testing is critical in all situations, even when tests are also automated. There is nothing that can really replace an observant, intelligent tester who has the skills to identify errors on the “edges”, to think a little outside the box, prioritize their work according to the current situation, analyze their observations and provide immediate and clear feedback. We can test in a detailed, formalized way or in a less formal, exploratory way. However, we will always be structured in our approach to ensure that testing is highly effective.

The need for integration testing grows with the complexity of digital systems, the number of interconnected services, and the frequency of releases. In environments where dozens of modules communicate with each other, it is crucial to verify their interaction quickly, systematically, and reliably. Production issues most often arise at the interfaces between systems – whether due to broken API contracts (breaking changes), semantic mismatches in data, or cascading failures caused by poor timing and timeouts. Through systematic integration testing, we help identify these risks early and prevent unnecessary costs.

Testing is tough work requiring intelligence and observation. Not only do Testers need to identify potential problems, but they also need to verify them with stakeholders, evaluate them in terms of their impact and risk, clearly and accurately communicate them to development and management. A good software tester has many hard and soft skills.

Our Test Managers are senior testing professionals. They will define and implement the test strategy and plan, and manage the day-to-day activities of the testing team. Through effective reporting to project management, stakeholders and sponsors they will ensure that the decision makers are receiving clear and accurate information about the progress of testing and the status of the software under test.

Focus on building quality at every stage of the software development lifecycle - especially when speed and quality both matter.

The need for API testing is growing alongside the expansion of digital services, microservices architectures, and the increasing number of integrations. APIs form the backbone of modern applications- any failure in communication can cascade and impact the entire system. Common issues - such as incorrect response schemas, missing input validation, or unhandled error states - can be effectively identified through targeted endpoint testing. Systematic API testing helps detect these risks early and ensures the overall stability of the solution.
