Quality assurance
Manual, automated and end-to-end testing that catches problems before your users do.
What we build
Testing we provide
We test software manually and automatically, build quality gatesAutomated checks in the pipeline that stop a release if agreed criteria aren't met. into your pipeline and report on quality release by release.
Test automation
Automated unit, API and end-to-end testsAutomated tests that drive the real interface through a full user journey. running on every change.
Regression testing
Replace long manual regression cycles with suites that run in minutes.
Performance testing
Load and stress tests that show how the system behaves at peak traffic.
Accessibility and security testing
Automated scans and manual checks against WCAG 2.2 and the OWASP Top 10:2025.
Mobile app testing
Apps tested on real and virtual devices across iOS and Android versions.
API testing
Contract and integration tests for your APIs and partner integrations.
How to get started
Three steps to a plan for quality assurance
- 1Tell us what you needUse the project form or book a call. A few sentences about the goal is enough to start.
- 2Free technical consultationWe go through your goals, users, existing systems and constraints with you.
- 3Your planA detailed plan covering the right tech stack, architecture, timeline and budget. Then you decide.
How it works
How we structure your tests
Many fast tests at the base and a few slow ones at the top, so feedback comes in minutes. Choose a layer, then compare with an inverted suite.
Mostly fast, automated tests: feedback in minutes.
Unit tests
Single functions and components, checked in isolation on every commit.
- Runs in
- Milliseconds
- Typical number
- Thousands
Tools: Jest, Vitest, JUnit, pytest
Every layer of the suite
The suites we build cover unit, integration, contract, end-to-end and performance tests, each catching different problems. Run each layer.

Services
Quality assurance services
Take one on its own, or combine them in one engagement with one team.
QA consulting and assessment
A review of your tests, defects and release process, ending in a test strategy.
Test automation
Automated suites in your CI/CD pipeline, starting with the critical journeys.
Manual and exploratory testing
Testers who find what scripts miss, every sprint.
Managed testing
A test lead and engineers running QA for your releases.
Our approach
How the work runs
Each stage hands its output to the next, like the stages of a delivery pipeline.
- Stage 1
Assess
Current tests, defect history, release process and the journeys that matter most.
- Stage 2
Strategy
A test strategy: what to automate at which level, and what stays manual.
- Stage 3
Automate
Suites built into the CI/CD pipeline, starting with the critical journeys.
- Stage 4
Gate releases
Quality gates that block a release when critical checks fail.
- Stage 5
Report
Dashboards for pass rates, coverage, flaky tests and escaped defects.
What we'll need from you
Having these ready keeps the work moving.
Environment access
Test environments, test accounts and safe test data.
Critical journeys
Product owners to confirm what must be protected first.
Pipeline access
Access to add tests to your CI/CD pipeline.
Defect history
Bug tracker access to find where problems cluster.
Who's on the project
Our team, working with product owners from yours.

Production
QA lead: Writes the test strategy and owns quality reporting.
Deliverables
What you receive
Everything is handed over in your name: code, accounts and documentation.
What the documentation looks like
Every project ends with documents your team can run with. Here is an excerpt of one of them.

Measuring success
How success is measured
What we report on in quality assurance projects. Which measures apply, and their targets, are agreed with you at the start.
escapedDefects
Escaped defects
Bugs found in production rather than in testing.
The release quality gate
Required checks on every pull request. Merging stays locked until they pass.

Readiness check
Are you ready for
quality assurance?
Five questions, about a minute. You'll see what to settle first and a sensible starting point.
? Do you know the user journeys that must never break? (y / n / ?)
How to start
From first call to production
Start where you are. Each step ends with a decision, so you commit to the next one only when it makes sense.

What it could be worth to you
Enter your own figures. The formula is shown, and the estimate can go with your enquiry.

Build or buy
When you don't need
a custom build
Part of the free technical consultation: when an existing product covers the need, we recommend it instead of a custom build. These are the options we weigh, alongside the tools you already have.
Automation in your pipeline fits when
- Tests must run inside your pipeline on every change
- APIs and integrations need contract and data tests
- Performance and security testing against your targets
- A test strategy tied to your architecture and risks

Questions
Common questions
about quality assurance
How much do you automate?
What runs often and is stable: regression checks, APIs and critical journeys. We keep people for exploratory testingUnscripted testing where a tester designs and runs tests on the fly, guided by risk., usability and anything that changes every sprint.
Can you test software another team built?
Yes. We start with the riskiest journeys, add automation around them, and report findings with clear steps to reproduce.
Do you do load testing?
Yes, with tools such as k6 and JMeter, against agreed targets for response time and throughput at expected and peak load.
How is a project priced?
Well-defined scopes are delivered as fixed-price engagements; when requirements are still evolving, we provide a dedicated team instead. Either way, the free technical consultation ends with a plan covering tech stack, architecture, timeline and budget, so you know the cost before work starts.
