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.

Erik Bolmsj about top software developers at LITSLINK
The LITSLINK team did an excellent job in developing an app from scratch. We were in need for designer/front end/ back end and it was all managed by a PM at LITSLINK. A very tight schedule was never a problem, and we are really overwhelmed by the quality and client focus of the staff at LITSLINK.

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.
