Our QA Testing Process



We collect and analyze information from stakeholders (a client, business analysts, designers, etc.) and develop a list of software requirements.



Before our team gets down to actual testing, we decide on the type of test documentation that best fits the project specifications. Whether it is an extensive test design, a set of test cases, or checklists, we develop all the required assets to ensure we cover the entire product development lifecycle.



Product testing starts at the early stages of software development. Once developers submit the first features, we perform functional and non-functional testing to ensure your product works the way you and your users expect. Our QA team also performs regression testing before the release.



Upon completing the testing process, our team creates bug reports and analyzes the results of their work.

Frequently Asked Questions

1. Do all projects require quality assurance?

Quality assurance is a vital part of the product development lifecycle. There is a common misconception that testing should be performed as a final step in the project.

The QA process starts at the very beginning when the development team submits the first features and functions to the app. A QA engineer's primary task is to test the product at every stage and ensure that everything the team delivers meets the project requirements. They verify and validate your product, which helps to build a seamless user experience.

By neglecting quality assurance, you risk releasing low-quality products full of bugs and inefficiencies, which would ruin your reputation on the market. Thus, it is always better to have a team of testers who will deal with all the vulnerabilities and ensure you get the product you can be proud of.

2. Do you follow quality assurance standards?

Sure, we apply the best practices and adhere to all the Software Testing Standards, such as the ISO/IEC/IEEE 29119.

3. What kind of QA software testing services do you provide?

We provide the full spectrum of QA services our clients might need. Our team of professional QA engineers performs all kinds of testing, including function, non-functional, regression, localization, usability testing and others.

The choice of QA services is highly dependent on the type of software you aim to build. For quality QA consulting services, reach out to us and we will analyze your request and come up with the optimal solution to meet your custom development needs.

4. Why should I outsource quality assurance?

Outsourced quality assurance might become a cost-effective solution for your app development project. If you are on a budget but need an experienced and qualified team to perform testing for your software product, outsourcing can perfectly meet your needs without compromising quality.

There are lots of software development companies out there ready to provide you with high-end QA services.
