With ISO 9001:2015, ISO 27001:2013 and ISEB accreditations, quality runs throughout our software testing services and sits at the centre of everything we do.

With our agile software testing services there’s no need to run the risk of expensive downtime and performance issues – our expert consultancy will help you develop software testing strategies and quality control procedures that identify potential vulnerabilities in your process, highlight opportunities for efficiency or saving, and minimise risk.

High-quality software testing services

Evidenced by ISO 9001 and 27001 accreditations, Box UK’s commitment to quality runs right across the company. Our internal software testing processes are subjected to the very strictest standards, all code goes through several levels of approval before it’s allowed anywhere near a live environment and at least 98% of bugs are caught pre-release.

QA metrics and Pillars of QA

An agile, test-driven development approach ensures the design and delivery of robust applications, and our project-specific QA teams (who lead the BBC’s testing framework) support both manual and automated software testing – targeting areas of particular interest and/or historical fragility to ensure your peace of mind. 

Along with the entire project team, our software testing consultants apply rigorous quality control processes to check that all QA activities have been completed and to confirm the development satisfies requirements. Each feature is subjected to testing to ensure both that it has been built correctly, and delivers what is needed.

Need help with targeted testing activities?

Our website and software testers can be deployed to your project to focus on specific tasks or areas, providing you with confidence where it’s needed most. Targeted activities may cover:

  • Load and capacity testing: trust in the ability of your site, application or system to withstand high numbers of users and still deliver the optimal experience to every visitor, with tests that simulate high levels of traffic and measure response times.
  • Penetration testing: evaluation of the security of your systems to validate existing protocols, and ensure potential threats, vulnerabilities and other risks are identified and addressed before they can negatively impact your business.
  • Automated testing strategies: our team will support you in identifying key tasks and processes that can benefit from automation, and set up testing frameworks with reusable scripts, to drive efficiency and effectiveness across your operations.
  • Manual testing support: if there are strategically-important pages and journeys that require specific focus, our experienced testers can augment your team with specialist knowledge and skills, increasing your rate of testing and adding a valuable extra layer of quality control.

Our tech stack

In order to be effective, software testing services must be underpinned by technology that’s robust, proven and well-supported. Not only does this support the creation of software that’s bug-free and fit-for-purpose, it also increases the speed with which features can be signed off and released.

Drawing on a variety of modern, flexible testing testing tools and frameworks, we select only the most appropriate solutions for each individual project, ensuring all code meets our incredibly high quality standards, every time. Here are just some of the technologies at our disposal, which we use alongside an extensive range of physical devices up to the very latest models:

  • PHPUnit – PHP unit testing library
  • PHPStan – PHP tool for carrying out static analysis of code
  • Jasmine – behaviour-driven JavaScript testing library
  • Karma – test running environment for JavaScript
  • PHP Codesniffer – PHP tool for checking code against a set of coding standards
  • NUnit – open-source unit testing framework for .NET
  • MOQ – mocking library for .NET for use in tests
  • BrowserStack – cloud-based automated software testing platform covering more than 2,000 real mobile devices, browsers and operating systems
  • Robot Framework – test automation framework for acceptance testing and acceptance test-driven development
  • Appium – used together with Robot Framework and BrowserStack CI to provide immediate feedback on compatibility with Android and iOS devices
  • ESLint – static code analysis tool
  • Behat – open source Behavior-Driven Development framework for PHP
Software Testing in Action


Over 100,000 medical professionals across the globe rely on the BMJ Best Practice App to inform their clinical decision-making. When we rebuilt the app from the ground up, then, ensuring the accuracy of all information was vital.

Employing a variety of testing techniques – including replicating real-world scenarios such as patchy network connections – we were able to safeguard the quality of the finished app, which now provides access to crucial information more quickly and easily than ever before.
