Quality Engineering

We build testing into the way your team delivers, with automated checks and clear release gates, so you ship more often and with fewer surprises in production.

Overview

When testing happens at the end, it becomes a bottleneck. Releases slip, bugs reach customers, and teams stop trusting their own test results because tests fail for no clear reason. Quality engineering moves checking into daily work: fast automated tests on every change, a few reliable checks before each release, and clear numbers showing whether quality is improving.

Bugs found in minutes, not weeks
Automated tests run on every change, so problems surface while the person who made them still remembers why.
Release without the long checklist
Quality gates in your pipeline replace manual sign-off for ordinary releases, and flag the ones that need a closer look.
Tests you can rely on
We remove flaky tests, keep suites fast, and report results in a way the whole team understands.

What we cover

The kinds of testing that matter most for modern web and mobile products, built to run on every change.

Test strategy and review
An honest look at how you test today, where the risk sits, and a plan for what to automate first.
Test automation
Automated checks for web, mobile, and APIs, written in code your engineers can read and maintain.
Quality gates in CI/CD
Checks that run on every change and block a release only when something important is wrong.
Performance and load testing
Tests that show how the product behaves with many users, before your customers find out.
Accessibility and security checks
Automated and manual checks built into the pipeline, with issues ranked by how much they matter.
Test data and environments
Reliable test data and stable environments, so tests fail for real reasons only.

What to test, and how

Not everything deserves the same amount of testing. We help you decide where to invest, and where to stop.

  • What should we automate first?

    How we approach it

    We list your main user journeys and the places bugs have cost you most, then automate those before anything else.

    What you get

    A ranked list of checks and a working suite for the most important journeys.

  • How much testing is enough?

    How we approach it

    We balance fast unit and API tests with a small number of full journey tests, and avoid heavy suites that slow everyone down.

    What you get

    A test mix that runs in minutes and catches the problems that matter.

  • What should block a release?

    How we approach it

    We agree gates with you: failing critical tests, security findings, accessibility failures, and performance limits.

    What you get

    Written release rules in your pipeline, and fewer arguments on release day.

  • What do we do about flaky tests?

    How we approach it

    We find the cause, fix or delete the test, and track flakiness so it does not creep back.

    What you get

    A suite your team trusts, with a failure rate you can see.

  • How do we know quality is improving?

    How we approach it

    A small set of measures: escaped defects, time to fix, test run time, and release frequency.

    What you get

    A monthly view of the numbers, with the changes that moved them.

Approach

We start with the risks that matter most, automate those first, and widen cover as the team gains confidence.

  1. Phase 1

    2 weeks

    Review

    • Look at your releases, bugs, and test process with your team
    • Find the highest-risk journeys and the slowest checks
    • Measure a baseline for defects, release time, and test run time

    You receive

    Quality review, risk map, and a ranked automation plan.

  2. Phase 2

    3 to 4 weeks

    Build the framework

    • Set up the test framework, data, and environments
    • Automate the first critical journeys and API checks
    • Connect the tests to your pipeline

    You receive

    A working suite running on every change.

  3. Phase 3

    4 to 8 weeks

    Widen cover

    • Add performance, accessibility, and security checks
    • Introduce quality gates, starting in warning mode
    • Coach your engineers to write and review tests

    You receive

    Release gates switched on and a team that can extend the suite.

  4. Phase 4

    Ongoing

    Keep improving

    • Track the quality measures every month
    • Remove flaky and slow tests
    • Add checks for new features as they ship

    You receive

    Monthly quality report and a short list of improvements.

Engagement models

Start with a review, set up a framework, or embed engineers in your team. You can combine them.

Quality review

Teams unsure where their quality problems come from.

2 to 3 weeks

  • Process and risk review
  • Baseline measures
  • Ranked automation plan
  • Recommendations for tools

Automation build

Teams ready to get core journeys automated and gated in the pipeline.

8 to 12 weeks

  • Framework and first test suites
  • Pipeline gates
  • Performance and accessibility checks
  • Training for your engineers

Embedded quality team

Products releasing often that need steady quality work alongside delivery.

Monthly, rolling

  • Quality engineers inside your team
  • Tests for every new feature
  • Monthly quality report
  • Scale up or down with notice

Standards and tools

How we keep tests reliable and trusted, and the tools we use to run them.

How we keep tests trustworthy

Tests live in your repository
All test code is in your own repositories and reviewed like any other code, so you keep it.
Honest results
We report failures and flaky tests plainly, and do not turn off checks to make a dashboard green.
Safe test data
Tests use synthetic or masked data, never real customer records.
Fast by design
We set time limits for each suite and keep to them, because a slow suite stops being used.
Shared ownership
Developers write and fix tests too. Quality is not left to a separate team at the end.

Tools we use

Web and API testing
Playwright, Cypress, Selenium, Postman, REST Assured
Mobile testing
Appium, Detox, XCUITest, Espresso, BrowserStack
Performance
k6, JMeter, Gatling, Lighthouse
Accessibility and security
Axe, Pa11y, OWASP ZAP, SonarQube, Snyk
Contract and unit testing
Pact, Jest, Vitest, JUnit, pytest
Pipelines and reporting
GitHub Actions, Azure DevOps, Jenkins, TestRail, Xray, Allure

We work with the tools you already have where they fit, and suggest changes only when there is a clear gain.

Frequently asked questions

Do you replace our testers?

No. We work with them. Manual testers move toward exploratory testing and risk work, where people are better than machines.

Which tools do you use?

Whatever suits your product and team. We start from the tools you already have and suggest changes only when there is a clear benefit.

How long until we see results?

Most teams have their core journeys automated and running on every change within 6 to 8 weeks.

Can you fix our flaky tests?

Yes. We find out why they fail, repair or remove them, and put in place checks that stop new ones building up.

Do you test mobile apps too?

Yes, on real devices and simulators, along with web and API testing, so one framework covers the whole product.

Can you work with a team that has no tests today?

Yes. We start with the few journeys that matter most and build from there, rather than trying to cover everything at once.
