Quality Engineering and Testing

Testing that starts with the paths customers use, and checks that run on every change.

Why It Matters

A release goes wrong when nobody tested the path customers use. The defect reaches production, the team reacts under pressure, and the next release is delayed while people search for the cause.

Manual testing does not scale with frequent releases. It is slow, it misses the same things each time, and it gives no clear answer about whether a release is safe. Performance and accessibility problems often appear only after users arrive.

What We Do

  • Checks that run on every change, catch breaks before customers do and name the path that failed.

  • We prove the system holds at the traffic you expect and beyond, and show where it breaks first.

  • We test the tasks people rely on with a keyboard and a screen reader, then report what blocks them.

  • Clear rules for what blocks a release, and a report that shows what passed and what is still open.

What Changes for You

  1. Checks run on every change and block a release when a core task breaks, so defects surface in the build.

  2. The team stops repeating manual checks and spends its time on the risks that need judgement.

  3. Results, trends and open risks are recorded for each release, so you can show what was tested and what passed.

How the Work Runs

Testing starts with the paths that matter, not with a tool. Each stage keeps the suite small enough to trust.

  1. Agree the Risks

    We agree the paths and risks that matter, and what should block a release. You provide the environments, test data and the release rules your team follows. We also record the checks you already run.

  2. Automate

    We write the checks and connect them to your pipeline. You decide which checks run on every change and which run before a release. Checks that only a person can judge stay manual.

  3. Test the Limits

    We test at the traffic you expect and beyond, and break parts on purpose. You agree the limits and the window for each test, and we compare the result with them.

  4. Keep It Useful

    We review failures and remove checks that no longer earn their place. You decide who owns the suite and how it changes. Each check keeps a named owner.

Team and Engagement Options

The team can join yours or work on a defined suite. You choose how much of the testing you keep in house.

  • Test engineers join your team and work beside developers. They write checks in your repository and attend your release reviews.

  • A team builds a defined set of automated checks for a release or product. The scope and result are agreed first.

  • Our specialists add capacity to your existing test team. They follow your tools, standards and release process.

Platforms and Technologies

We use the tools that fit your stack and keep the checks in your repository. Playwright, Cypress, Selenium and Appium drive a browser or a device, while Jest, JUnit and pytest check code. k6 and JMeter apply load, axe checks accessibility, Postman tests interfaces, and OWASP ZAP looks for security weaknesses. GitHub Actions and GitLab CI run the checks on each change.

Questions

What teams ask before they change how they test.

How do we start?

We agree the paths and risks that matter most. You give us access to a test environment, test data and your release process. The first checks run early, on the paths you chose.

What shapes the effort testing needs?

The number of paths, environments and systems, plus the state of the current tests. Performance and accessibility testing add effort. We agree what the tests must cover before any are written.

When do we see results?

The first automated checks run early and show what they catch. A full suite grows with each release. You see the results on every change, not only at the end.

Do we own the tests?

Yes. The checks live in your repository and run in your pipeline. Your team can change them, and we document how they are built and maintained.

What should we not automate?

Not every check is worth keeping. We avoid automating one-off features, changing screens and judgements that need a person. A smaller suite that people trust is worth more than a large one they ignore.
