Can you add tests to an existing untested codebase?

Yes. We start with the highest-risk paths, add integration and end-to-end tests around them first, then build out coverage so refactoring becomes safe over time.

Do you automate everything?

No. We automate repetitive, high-value checks and keep manual testing for usability, exploratory and one-off scenarios where human judgement finds more than a script would.

Can you test security too?

Yes. NUEXUS runs an in-house security team, so we can add vulnerability scanning and full penetration testing to QA for systems that handle sensitive data.

QA and testing

Software & Web Development

Quality assurance and testing

Catch bugs before your users do, with automated and manual testing that actually covers risk.

We build quality assurance into the development process, not as an afterthought: unit, integration and end-to-end tests run automatically on every change, and a CI pipeline blocks broken code from merging. We add manual exploratory, regression and usability testing where human judgement matters, plus performance and security testing for high-stakes systems. You get fewer production incidents and a test suite that protects you on every release.

How we engage

A clear path from problem to outcome

Discovery and scope

We map the problem, users and constraints, agree the requirements, and define a clear scope with milestones, a technical approach and success criteria you can hold us to.

Architecture and design

We choose the right stack, data model and API contracts, design the user experience, and plan for security, performance and scale before a line of production code is written.

Build and iterate

We ship in short increments with automated tests and code review, demo working software each sprint, and adjust to your feedback so you see progress, not a black box.

Release and support

We deploy through a CI/CD pipeline, hand over clear documentation, set up monitoring and alerting, and provide ongoing maintenance so the system stays secure and reliable.
