Types of our software testing

It is equally important to perform non-functional testing in addition to functional testing. To ensure that teams are conducting a mix of different types of testing, both types of testing must be completed during the quality assurance services complex. That is essential to having QA and testing services work just as expected.

  • Functional testing

    As a type of software testing, functional testing involves validating the software system against its functional specifications. Tests are performed to ensure software functions are working as intended by giving adequate input and comparing the received result with the requirements.

  • Non-functional testing

    Software non-functional testing examines the non-functional features of a software application (performance, usability, dependability, and so on). The non-functional test aims to assess a system's readiness based on criteria that never appear in functional tests.

Our QA services lifecycle

With decades of QA experience, we know precisely the best way to start our future cooperation. Meet our QA as a service lifecycle:

Quality assurance & testing services start with your project documentation audit to know your key goals and features from top to bottom and prepare the perfect test plan considering all your essential needs.

We will identify test situations, create the most common test cases, and define the test starting point, completing our test scenario. Developing a piece-of-mind testing automation if you require it.

During the implementation stage, functional and non-functional testing is performed. Following the test cases established, errors are discovered and reported. QA ensures that the features are constructed and work in line with the requirements supplied.

Our team completes the full regression test to exclude any script sabotage and be 100% sure that everything is nice and steady.

After the successful acceptance testing and scope verification, our QA team provides the final test results and performance review with detailed information about criticals and deliverables.

Client feedback


I was most impressed by the quality of the end product.

While my ideas formed the basis for the work, they delivered a far more superior product than I imagined with greater flexibility and viability of features. They exceeded expectations so many times it got to the point I couldn't wait to see what they came up with next.

Dan Brooks

President, Krytter

COAX have delivered immense value to our business as our valued strategic development partner.

I implicitly trust the whole COAX team to do the right thing by location:live, and to have blunt and honest conversations with me when we are in the thick of delivery. COAX are the engine room and compass behind our market-leading tech.

Neil Winkworth

CTPO, Location Live

For almost 10 years now, I’ve enjoyed working with COAX Software on various projects.

Their team of highly talented, cross-functional software engineers and architects helps us meet development timelines quickly and reliably.

Joseph Heenan

CEO, Proteineer

The solution created by COAX is better than I could have anticipated.

The app is simple to use, effective, well designed and never fails. Highlights of the COAX service are a clear, transparent specification with realistic cost estimate, project managers that are responsive, always helpful and communicate clearly, a strong technical team and a company that I can trust.

Phil Cushion

Founder, SiteSurvey Plus

I heavily relied on COAX for not only the development of my core product, but also assistance in all the other support infrastructure in hosting my product.

The team also went above and beyond their existing web development skillset by making effort to understand the domain specific (financial modelling) math and technicalities of my product.

Tim

Founder, Peercents

COAX’s team is second to none designing, developing, and deploying websites.

I was delighted by COAX attention to detail and ability to deliver such a complex project. I highly recommend COAX to anyone looking for a reliable and talented web development team.

Mason Blake

Co-founder and CTO, Ratio

In working with COAX, we found them to be highly professional.

We have continued our ongoing relationship and cooperation with COAX on this project thanks to the ongoing support they continue to offer us.

Ashley Greenfelder

Director, Re:Plan

Their highly responsive team had the technical know-how to seamlessly incorporate non-standard features.

Despite facing tight crucial deadlines, they worked tirelessly around the clock to deliver the project on time, even accommodating additional feature requests. We are immensely thankful for their hard work, which resulted in exceptional outcomes.

Ali Ghafour

CEO, 2020 Armor

Throughout the years, we have maintained a strong relationship based on mutual trust and respect.

From the start, we prioritized flexibility, particularly in terms of working within our monthly budget and delivering new features and functionalities every two weeks. Our communication with both the project manager and team members has been exceptional, and we have consistently received high-quality product delivery and support.

Andrew Macfarlane

Founder & CEO, Carezapp

You will not often find such an approach in the outsourcing development market.

From the first day, the COAX team established themselves as optimistic. After the guys spent a dozen hours sorting out our problems and never once talked about money, we realized that this team was ready to go the extra mile. We were finally convinced of the prospects for cooperation when the COAX CTO came to our British office in person with a detailed presentation of the renovation.

Richard Murray

CEO, Antique Ecommerce Marketplace

We liked the COAX team’s deep-diving approach and attention to detail.

Their incremental approach with feedback loops allowed us to see results from the early stages and ensured we stayed on the right track. But most importantly, we felt that they genuinely cared about our project. Doing their best to make it as perfect as possible, they were always there for us, on-site rather than online.

Mykola Bronitskyy

Co-founder, GrandBus

They always respond right away to any questions or requests that we have and contribute really good ideas.

The development work delivered by COAX has satisfied all project stakeholder requirements for the project and helped to streamline internal company processes for the client. Their team is communicative and helpful throughout the work, contributing ideas to make the product even better.
