Software testing and QA services

Get an Estimate

Quality matters, you know it from your own experience, facing obstacles on numerous fronts, including software, devices, and system interfaces. And our team would be the one who will guide you as a certified QA services company.

Developing and maintaining quality standards is more accessible by preventing problems from occurring in the first place, which saves costs and fixes issues before they become more prominent.

Our QA and software testing services

Quality Assurance consulting

Every revenue-driving business must focus on its software testing process before it goes live to maintain its confidence and human friendly. COAX QA consulting services are brought to assist companies in managing their software testing services and clients across the SDLC. Side by side with you, we provide a wide range of QA & testing services, from scratch to implementation.

Automation testing

Quality assurance and testing services automation help you deliver your products more efficiently and effectively. Our certified software testing & QA services team employs the most up-to-date automated testing techniques to verify that our products perform consistently across various releases.

Manual testing

Ensure your product is delivered defect-free and on schedule by combining COAX manual testing methodologies, tools, technical experience, and domain expertise. We use manual software QA services testing methods to recreate user behavior, follow consistent practices, verify various scenarios, and remove as many system flaws as possible before launch.

Performance testing

Your users expect your app to have a perform perfectly. They abandon pages that don't deliver, and every lost visit is a lost customer. Our QA testing services cover load testing, stress testing, and performance benchmarking to ensure your app holds up under real-world conditions and keeps users coming back.

SEO testing

No worries, that is just a breeze for our SEO testing team. We will analyze your off-page and on-page health and POV in search results and implement the necessary fixes quickly.

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.

You have a vision. We take care of quality
