Quality Assurance: Ensuring Excellence

Deliver high-quality products that meet client expectations and provide an exceptional user experience

At all phases

Our projects work steadily and are done efficiently, reliably, and on time due to the well-established quality control and testing processes.

Our QA department is actively involved in the development process at all stages and keeps up with modern technologies. We are constantly improving our methodology, approaches, and toolset to deliver high-quality web development solutions.

Requirement Analysis

At the preliminary analysis stage, testing specialists are connected to the project to ensure that they understand the global goal and can create reasonable test scenarios. This is important because it helps identify potential issues and areas that need improvement early on.


Identifying ambiguous and problematic areas during the preliminary analysis of user scenarios is crucial in preventing difficult situations in advance and providing solutions even before development begins. This helps ensure that the development process is smooth and that the final product meets the client's expectations.

Development Phase

QA control takes place during the development phase to ensure compliance with technical requirements, user scenarios, and design layouts. This involves testing the functionality of the project, identifying bugs, and providing solutions to ensure that the final product is of high quality.

Release Testing

When forming preliminary or final releases, QA specialists carefully check all the released functionality and the compliance of the release with the work plan and the required quality level. This ensures that the product is of high quality and meets the client's requirements and expectations.

Non-Functional Testing

In addition to testing the project's functionality, we check other aspects, such as convenience, speed, and security.

Non-functional testing ensures that the product is user-friendly, efficient, and secure.

Regression Testing

As new features are added or defects resolved, QA teams perform regression testing to ensure that the changes have not introduced new issues or negatively affected existing functionality. This ensures that the product remains stable and functional even after updates are made.


Documentation is an important part of the quality assurance process in web development. It helps keep track of the project’s progress, reduces communication gaps, and ensures that all team members are on the same page.

And so that specialists know what exactly and how deeply to check at each phase of the project, we practice preparing user stories, checklists, sets of test cases for all functional units of the project

User Stories

User stories are short descriptions of what the user wants to accomplish with the system.

These stories capture the user's requirements and objectives, and they serve as a reference point throughout the development process. User stories can help the QA team understand the project’s goals, design effective test cases, and ensure that the system meets the user's needs.

Test Cases

Test cases are sets of instructions that describe how to test a specific feature or function of the system.

They are used to ensure that the system is functioning as intended and to identify any defects or errors. Test cases help the QA team identify areas of the system that require additional attention, and they are used to verify that the system meets the specified requirements.


Checklists are a set of items that need to be completed before the project is considered complete.

They are used to ensure that nothing is overlooked and to provide a final quality check. Checklists can be used for both functional and non-functional requirements, and they can help ensure that the project meets all of its specifications.


Reports are used to document the results of the testing process and overall quality.

They provide an overview of the project’s progress, identify any issues that were encountered, and provide recommendations for improvement. Reports are essential for communicating the testing results to management and stakeholders and tracking the project's overall quality.

For organized work on testing projects, so as not to miss certain scenarios, we practice preparing user stories, checklists, sets of test cases for all functional units of the project, and reports.

This ensures that the testing process is organized, thorough, and efficient.

In addition to various testing environments, we have a solid set of real devices on all of the popular platforms: MacOS, Windows, iOS, Android and Linux. We update the device fleet as a new generation appears.

Non-Functional Testing

In addition to testing the functionality of the project, we carry out checks on other aspects, such as convenience, speed, and security.

Non-functional testing ensures that the product is user-friendly, efficient, and secure.

Non-Functional Testing is a type of testing that verifies the non-functional requirements of a web application

Unlike functional testing, which checks whether the application functions correctly, non-functional testing checks how well the application performs in terms of user experience, reliability, and security.

Here are some details about non-functional testing:

Performance Testing

This testing type checks the application's responsiveness and speed under different loads. It includes load testing, stress testing, and endurance testing

Usability Testing

Usability testing checks the user-friendliness of the application. It includes testing the ease of use, accessibility, and navigation of the application

Security Testing

Security testing checks the security of the application. It includes testing for vulnerabilities, authentication, authorization, and pen-testing

Scalability Testing

Scalability testing checks the ability of the application to handle a growing number of users and data

Recovery Testing

Recovery testing checks the ability of the application to recover from failures, crashes, and errors

Compliance Testing

Compliance testing checks the compliance of the application with industry standards and regulations

By performing non-functional testing, you can ensure that your web application meets your users' expectations and delivers a high-quality user experience

It helps you identify and resolve performance, security, and usability issues before the application is deployed to production.

Load Testing

We work with high-load and multi-user projects, and an important part of working on them is the ability to keep a high load and ensure the stability and high speed of the system even at peak loads.

To achieve this, we perform load testing during the development process, when publishing releases, and before launch, to check the metrics and limits of the load on the system.

This allows us to carry out optimization work in advance or change the solution or architecture of modules where bottlenecks were identified under load.



Security is of primary importance, especially if the project deals with critical or valuable data.

It is crucial to ensure that the system is protected from attacks and unauthorized access. Penetration testing, also known as pentesting, is the process of checking the system for compliance with security requirements and identifying potential vulnerabilities that could be exploited by attackers.

During pentesting, the system is thoroughly tested by simulating various types of attacks to identify potential security risks. This includes testing for known vulnerabilities, analyzing the security of the infrastructure, checking the system for unauthorized access, and more. Pentesting helps to identify weaknesses in the system and develop strategies to mitigate them.

Automatic Testing

For large projects with a complex set of functionality, manually testing all modules takes a considerable amount of time, which can impact the timing of releases and the cost of maintaining the code.

Automated testing allows you to check stable, unchanging functionality in an automatic mode, without involving QA specialists, in much shorter terms than human testing.

With automated testing, developers write scripts that automate the testing process, including executing test cases, comparing actual and expected results, and reporting bugs. Automation testing is especially useful for regression testing, where previously tested functionalities are tested again, to make sure that new changes didn't break the existing features.


Quality assurance is an indispensable aspect of web development, ensuring that websites and applications meet high-quality standards and deliver a positive user experience

By implementing robust QA processes and leveraging cutting-edge tools and methodologies, developers can create exceptional web solutions that stand the test of time and cater to the ever-evolving needs of users
