This early phase establishes clarity around business logic, technical constraints, and key product flows. It also defines supported platforms and environments—laying the foundation for a well-aligned development cycle.
What you gain:
2
Instead of applying a one-size-fits-all approach, our QA experts develop a customized and thorough testing strategy tailored to your goals, timelines, and team dynamics. We determine the appropriate test techniques—balancing manual and automation efforts—based on system complexity, release cadence, and quality benchmarks. Optional paths for performance, security, and compliance testing are built in as needed.
3
We translate your product goals into executable test cases, scripts, and exploratory plans—backed by well-defined data and environment needs. All assets are managed using centralized test management tools, enabling visibility across teams and ensuring comprehensive coverage across functional and non-functional layers. At this stage, quality assurance and software testing activities begin to take shape, supported by structured processes and fully traceable documentation.
4
Our team runs manual and automated tests across key user flows, APIs, and backend operations, embedding continuous testing into your delivery pipeline. We identify critical defects early and ensure traceable reporting to reduce late-stage surprises and speed up feedback cycles. This stage significantly improves software reliability and user satisfaction.
5
Before release, we retest all resolved defects and re-execute regression suites. If included, we perform acceptance testing to verify new functionality and confirm there’s no negative impact on existing features. Our focus is to guarantee that the final product meets both business goals and user expectations across multiple platforms.
6
After testing is complete, we deliver detailed QA reports covering coverage, risk areas, and actionable insights. Whether for short-term assessments or long-term managed testing services, this phase supports the continuous enhancement of your software systems through performance metrics and root-cause analysis.
We really care about project success. At the end of the day, happy clients watching how their application is making the end user’s experience and life better are the things that matter.

“Quality of delivered work is outstanding”
Our company worked more than 5 years in total with NIX. Communication was always very clear and direct. Being a remote company, wasting time in communication is horrible, luckily with NIX, we experienced no delay or misunderstanding.
Quality of delivered work is outstanding, all tasks prior to delivery were tested in detail, and bugs or mistakes were virtually non-existent.

“Delivering high-quality code”
With NIX, I have broken some of my own rules of team composition with respect to the ratio of FTE and 3rd party engineers. I have some teams that are more than 50% NIX because the code coverage, quality, and velocity coming out from the NIX developers are very good. Delivering high quality code in a predictable manner has built trust and confidence with my management/full-time employees.
