09 · Quality Engineering & Testing

Release often without breaking what works.

We make testing part of how software gets built instead of a phase at the end: a strategy that says what to test and how deeply, automated suites that run on every change, and the performance, accessibility and device testing that automation alone misses.

When teams call us

You might be here because…

  1. 01Every release breaks something that used to work.
  2. 02Manual regression testing takes days, so releases wait.
  3. 03The app slows down or falls over when usage peaks.
  4. 04Customers, procurement teams or the law expect accessibility, such as WCAG 2.2 or the European Accessibility Act.
  5. 05You have tests, but nobody trusts them because they fail at random.

01What we build

Quality Engineering & Testing, in practice.

  • 01

    Test strategy

    What to test, at which level and how deeply, decided by risk: a written plan that fits how often you release, not a coverage number.

  • 02

    Test automation

    Unit, integration and end-to-end suites with Playwright, Cypress, Vitest or the tools you already use, running in your pipeline on every change, with flaky tests fixed rather than ignored.

  • 03

    API and contract testing

    Tests that pin down the behavior of your APIs and the contracts between services, so one team’s change can’t silently break another’s.

  • 04

    Performance and load testing

    Realistic load run with k6 against response-time and error budgets, to find the bottleneck before your users do.

  • 05

    Accessibility testing

    Automated checks plus manual keyboard and screen-reader testing against WCAG 2.2 AA, with fixes your designers and engineers can apply.

  • 06

    Mobile and cross-browser testing

    The devices and browsers your users actually have: layouts, gestures, offline states and the versions you still support.

02How we hold the line

The standards that come with it.

Risk decides depth
Critical paths get the most testing. Fewer tests that catch real failures beat a high coverage figure.
Tests you can trust
A flaky test is treated as a bug. Suites are fast enough to run on every change and clear about why they failed.
Built in, not inspected in
Testing runs alongside development, in the same pipeline and the same definition of done.
Standards we test against
WCAG 2.2 for accessibility, service-level objectives for performance and ISTQB terminology for test planning. We say “aligned with”, never “certified by”.

03Across the loop

How this practice shows up at every stage.

    Design

    Acceptance criteria and testability decided with the design.

  2. 02 · 060°

    Engineer

    Tests written alongside the code, in the same change.

  3. 03 · 120°

    Integrate

    Contract tests at every API and integration boundary.

  4. 04 · 180°

    Secure

    Security checks in the same pipeline as the functional tests.

  5. 05 · 240°

    Scale

    Load tests against the traffic you expect, before it arrives.

  6. 06 · 300°

    Maintain

    Regression suites kept fast and green as the product changes.

05How engagements run

How engagements run

  • Quality assessment

    A short review of your tests, pipeline and release process, with a prioritized plan.

  • Automation build-out

    We build the suites and the pipeline, then hand them over with the know-how to keep them green.

  • Testing as a service

    Ongoing testing for every release: regression, new features and devices, by a team that knows your product.

Questions

What people ask first.

No. We test existing products too, alongside your developers or another vendor. On our own builds, testing is part of delivery rather than a separate line item.

Both, for different jobs. Automation covers what must never break and runs on every change. People cover what automation is bad at: exploratory testing, usability, accessibility with assistive technology and features still taking shape.

Yes. We extend the frameworks and pipeline you already have unless they are the problem, and if we suggest a change we explain the cost and the benefit first.
