Functional Testing

We check whether the product meets the specified functional requirements - each module must work clearly according to expectations.

Non-functional Testing

We evaluate performance, security, usability and other characteristics that are not directly related to functionality.

Automated Testing

We create and use scripts and frameworks to speed up the testing of repetitive scenarios and reduce the human factor.

Manual Testing

Experienced QA specialists manually test the product in complex or non-standard cases where automation is impractical..

Regression testing

We ensure stability after code changes — we identify possible violations in the already implemented functionality.

Integration testing

We check the interaction between individual modules and components to avoid conflicts and errors at the joints.

System testing

We evaluate the operation of the entire system as a single whole before releasing it to production.

Security testing

We identify vulnerabilities that could lead to data leakage or product compromise.

Performance testing

We check how the system behaves under load — we determine its stability, responsiveness, and scalability.

Requirements analysis and risk assessment

We check the completeness, consistency and testability of requirements to minimize the likelihood of critical errors even before the start of development.

Development of a testing strategy

We create a flexible QA action plan adapted to the specifics of the product, business goals and end-user expectations.

Formation of test documentation

Preparation of test cases, checklists, scripts and supporting documentation for full functionality coverage.

Automated and manual testing

We conduct modular, integration, system, regression and acceptance testing using modern tools and frameworks.

Quality Control of Development Processes (QC)

We implement internal standards compliance practices, code reviews, and regular product quality audits.

Continuous integration of QA into CI/CD

We ensure release stability and fast feedback through automatic quality checks at each stage of delivery.

FAQ

What is the difference between QA and QC?

QA (quality assurance) is a strategic approach that includes planning, processes, and standards to prevent defects. QC (quality control) is the practical part that involves detecting errors in the finished product through testing.

Can your QA team be integrated into an existing project?

Yes, we easily integrate into current teams and processes. Our flexibility allows us to work at any stage of the product lifecycle — from planning to post-release support.

What technology stack do you use for automated testing?

We work with tools such as Selenium, Cypress, Playwright, Postman, JMeter, Appium, TestNG, Jenkins, Allure, and others — depending on the project's tasks and architecture.

Do you test mobile applications?

Yes, we perform both manual and automated testing for iOS and Android, including functionality, UX, performance, and security testing.

How is the effectiveness of QA processes evaluated?

We use metrics such as defect rate, time to detect/remove bugs, test coverage and regression frequency. We also regularly provide reports with analytics for transparent quality control.

Do you audit existing testing processes?

Yes, we can analyze your current QA processes, identify weaknesses, and suggest improvements to increase efficiency and product quality.

What collaboration models do you offer?

We work with outstaffing, outsourcing, or dedicated team models — depending on your business goals, scope of tasks, and project duration.
