Quality assurance

Excellent quality is non-negotiable – it simply must come as standard. Nobody wants to get derailed by bugs, so we’ve developed a way of working that delivers everything to exceptionally high standards.

What we do

Automated testing

Our ‘automate everything’ culture keeps manual testing to an absolute minimum. We automate every stable flow we can. We use Playwright for web and Appium for mobile, running tests continuously through CI/CD pipelines so we catch issues immediately.

Cloud testing platforms like BrowserStack give us access to a wide range of real devices and browsers, so we know exactly how your product behaves before we ship it.


Manual Testing

We go manual when automation is prohibitively expensive, less effective, or simply impossible.

Some elements and interactions are best checked with the human eye. Automation handles the repeatable flows. Manual testing handles the edge cases, the unexpected paths, and everything else no test case or automation script can cover.

Why it works so well

Quality that enterprise-level software demands

We understand the complex requirements of the world’s largest brands, and we’re trusted by leading enterprises to deliver to the highest standards.

Rigorous test plans

We map out exactly how and when tests are carried out, accurately allocating time during each sprint, alongside regression plans and test cases to be covered manually.

In the room from day one

QA is there at kickoff, not brought in at the end. That means we’re questioning requirements, defining acceptance criteria, and catching edge cases before development even starts. Faster, easier and cheaper than dealing with problems after deployment.

Product-minded, not spec-driven

Ticking off requirements is the easy part. When we build and test a feature, we think about who’s actually using the product, what they’re trying to do, and whether it genuinely solves the problem. Owning the product is the standard we hold ourselves to.

AI-assisted testing

We use AI where it genuinely speeds things up. Drafting test cases, writing and updating automation scripts, summarizing tickets. The repetitive, predictable work. That frees our engineers to focus on the things AI can’t do well: exploration, judgment, and edge cases.

We make quality everyone’s job

Quality isn’t something QA owns and everyone else ignores. Every engineer, PM, and designer has a part in it. We set the standards and make them easy to follow.


How our developers and QAs work together

Developers test what they build. QAs test how it’s built. Watch Marko Brajer, QA Team Lead at DECODE, explain why both perspectives are essential, and why full test coverage only happens when developers and QA engineers work together.

Tools we use

playwright

Playwright for web automated testing

Ideal for testing across multiple OS, browsers, and devices, providing robust cross-browser automation with native support for modern web features.

Appium

Appium for mobile automated testing

A versatile tool for automating tests across iOS and Android platforms, supporting native, hybrid, and web applications with seamless cross-platform compatibility.

BrowserStack

BrowserStack or SauceLabs for testing farms

Farms help us improve quality by testing across an extensive range of desktop browsers and real mobile devices.

Selenium

Selenium for web automated testing

A widely-used tool for automating browser actions across multiple OS and browsers, ideal for ensuring compatibility and functionality in web applications.

Postman

Postman and Charles for API testing

Our preferred way to streamlining collaboration between testers and developers so we can create, test and deploy better APIs, faster.

An open source load testing tool.

Locust for load testing

A powerful tool for simulating millions of users to test and measure system performance under heavy load, providing valuable insights for scalability and stability across different environments.

testrail

TestRail for test case management

An intuitive tool for organizing and tracking test cases, offering advanced reporting and seamless integration with various CI/CD tools for efficient test management.

azure test plan

Azure Test Plans for integrated testing

A comprehensive testing solution within the Azure DevOps ecosystem, ideal for managing and automating tests with built-in workflows and Azure Pipelines integration.

Powerful quality assurance with Shake

Our sister company Shake’s products allow our clients to easily report all app issues, give documented context reports and monitor application behavior, helping developers communicate with testers, designers and users.

See how we built Shake →

We build internal tools too, like a Chrome extension that makes bug reports consistent across different Jira instances. Pair that with Atlassian’s Rovo AI, and you can write two or three sentences describing a bug and it fills out the rest of the template for you: steps, expected behavior, actual result. That saves us anywhere from 5 to 20 minutes per bug.
