Ship with confidence, not hope

Software that hasn't been properly tested hasn't been finished. We find defects before your users do and give your team the confidence to ship quickly without sacrificing quality.

Defects cost more in production than in testing

We help brands ship faster
 with fewer surprises

We embed quality throughout the development lifecycle, not just at the end. From test strategy to performance validation, we provide the rigour that lets your teams move fast without breaking things.

Our testing services capability

We take a quality-first, shift-left approach to testing, integrating QA throughout your development process rather than treating it as a final gate.

Test strategy & planning

We define the testing approach, establishing what needs to be tested, how, and what the acceptance criteria are.

Manual functional testing

We conduct structured manual testing against defined requirements, documenting every defect with the detail needed.

Automated testing

We build automated test suites for regression coverage and continuous testing across your development pipeline.

Regression testing

We maintain regression test suites that verify existing functionality continues to work correctly as your product evolves.

Performance & load testing

We test your application under realistic and peak load, identifying bottlenecks and capacity limits visible only at scale.

Security testing

We integrate security testing into your QA process, running vulnerability scans, manual testing, and adversarial testing.

Accessibility testing

We test against WCAG 2.2 standards using automated tools and screen reader evaluation, identifying every access barrier.

API testing

We test your APIs across functional correctness, performance, security, and edge cases for reliable production behaviour.

Mobile app testing

We test mobile apps across the device landscape, covering functionality, performance, and platform requirements.

User acceptance testing

We facilitate UAT with your stakeholders, managing the process and ensuring every finding is acted on before launch.

Our partnership with Atomic has been essential in delivering a new level of digital convenience for our guests. The app enriches each stage of their short break, aligning perfectly with our commitment to offering the best possible guest experience.

We succeed together.

How we built a No.1 app 
for Center Parcs guests

Over 70,000 downloads in its first week, a 15% uplift in bookings, and No.1 in the travel app charts. We designed a native iOS and Android app that made it simpler for Center Parcs guests to plan, book, and get the most from their stay.

Our testing approach is built on one thing:
Quality is engineered in, not inspected at the end

Test early and continuously

We integrate testing into every stage of development, from requirements review through to acceptance. Defects caught early are cheapest to fix.

Automate the right things

We automate regression and repetitive work, freeing testers for the exploratory testing and adversarial thinking that automation cannot replicate.

Report with clarity

Our reports communicate what was tested, found, and what's next. Prioritised by severity so your team fixes the right things in the right order.

We keep defects away from your users

Atomic's testing team provides the manual and automated quality assurance your software needs to reach production in the condition your users expect and your business requires.

Got questions about our testing services? We've got answers.

Get in touch

Software testing is the process of verifying that your product works as intended, identifying defects before they reach users and ensuring quality is built in throughout development.

Manual testing involves a person executing test cases to find defects. Automated testing uses scripts to run checks repeatedly and quickly. Both have a role in a thorough testing strategy.

Throughout. Testing only at the end is expensive and risky. Shifting testing left, starting early in development, catches defects when they're cheapest to fix and least disruptive.

Functional testing, regression testing, performance testing, security testing, accessibility testing, cross-browser and device testing, and API testing, scoped to what your product needs.

By risk and user impact. We focus testing effort on the most critical user journeys, the highest-risk components, and the areas most likely to contain defects based on complexity and change.

We build regression test suites covering the most critical functionality and run them after every significant change, catching any unintended side effects before they reach users.

Testing investment varies by product complexity, testing scope, and the mix of manual and automated work required. We scope every engagement individually and give a clear estimate upfront.

Timeline depends on the scope of testing and the state of the product. A targeted test cycle for a release typically takes one to two weeks. Larger programmes run alongside development.

Access to your product or test environment, any existing test documentation, and a clear brief on what needs to be tested and the risks we should prioritise.

Yes. We regularly provide independent testing for software built by other agencies or in-house teams. Independent testing catches things internal teams, too close to the work, often miss.
