Software Testing and Quality Assurance
Get better software to market faster –
Build the right thing, the right way from day one
At Nimble Approach, we believe testing and quality assurance should be considered from the very start.
We ask questions, challenge assumptions, and ensure your project maintains the highest standards throughout the software development lifecycle.
Our shift-left testing philosophy is embedded in everything we do. By integrating testing early, we help you deliver higher quality software, faster.

Full Stack Automated Testing
From frontend to backend, we implement and scale automation using tools like Playwright, Cypress, Selenium and more – ensuring end-to-end coverage and scalable, modern testing architectures.
Regression Testing
Ensure new changes don’t break existing functionality with comprehensive regression test suites that support fast, iterative delivery.
Mobile Testing
Ensure apps work flawlessly across devices, platforms, and screen sizes – keeping real user experience at the centre. Including specialised QA testing for iOS and Android applications.
Accessibility Testing
Your software needs to be accessible to all users. Audit and enhance digital accessibility – from WCAG compliance to real-world usability with screen readers and keyboard navigation.
Performance Testing
Identify bottlenecks and optimise your application’s speed and responsiveness using tools like JMeter and K6 – ensuring your systems perform reliably under real-world and cloud-scale conditions.
Scalability and Resilience Testing
Don’t let scaling hold you back. Ensure resilience and scalability by identifying and solving bottlenecks and validating your architecture for sustainable, long-term growth.
Security Testing
Evaluate security vulnerabilities and implement protective measures with secure-by-design principles, utilising static application security testing (SAST) and dynamic application security testing (DAST) capabilities – supporting safe, modern and reliable digital services.
Coaching, Workshops and Mentoring
Upskill your teams. We offer training sessions, 1:1 mentoring and embedded coaching to raise your internal capability and create lasting change.
AI-assisted Testing
Using tools that leverage machine learning to improve test coverage, accuracy, and delivery speed.
Testing AI-driven Systems
Helping teams think critically about how to validate behaviour when AI models are involved, ensuring responsible, explainable and reliable outcomes.
Strategic Guidance
Supporting organisations to test responsibly in data-rich, AI-influenced environments.
”Now, with thanks to our new testing approach and strategy, we can evidence we have much more performant, secure and accessible applications which are ready to take over from the legacy applications.

Frequently Asked Questions
About Software Testing
What is the difference between QA and software testing?
Quality Assurance (QA) is a proactive process focused on preventing defects by improving development processes, while software testing is the actual practice of evaluating software to identify bugs and verify functionality. At Nimble Approach, we combine both: implementing quality processes throughout development (QA) and conducting thorough testing to validate results.
What testing methodology does Nimble Approach use?
We adapt our testing methodology to each client’s needs rather than forcing a one-size-fits-all approach. For Agile environments, we implement continuous testing practices integrated with CI/CD pipelines. For more traditional projects, we can provide structured test plans with clear phases. Our approach always emphasises shift-left principles—introducing quality considerations as early as possible in the development lifecycle.
How does automated testing compare to manual testing?
Manual testing leverages human intuition and exploratory skills to find unexpected issues, while automated testing excels at repetitive verification and regression testing. The best strategy combines both: automated testing for consistent, repeatable test cases, and manual testing for exploratory scenarios and user experience evaluation. At Nimble, we help clients determine the optimal balance based on their specific needs.
How can we measure the ROI of investing in software testing?
The ROI of effective testing manifests in several ways: reduced production bugs (saving costly fixes), faster release cycles, reduced customer support tickets, and improved customer satisfaction. We work with clients to establish metrics before implementing testing improvements, then track these over time to demonstrate tangible value, such as reduced defect escape rates and decreased time spent on bug fixes.
How do you handle testing for accessibility compliance?
We implement a comprehensive approach to accessibility testing that includes automated WCAG compliance checks, manual testing with assistive technologies like screen readers, and expert review of content and functionality. With the European Accessibility Act implementation approaching, we help clients understand their compliance obligations and implement sustainable testing practices to meet these requirements.
What's your approach to testing AI and machine learning systems?
Testing AI systems requires specialised approaches beyond traditional testing. We focus on evaluating training data quality, algorithm performance across diverse scenarios, monitoring for bias, and ensuring proper model validation. For generative AI specifically, we test response quality, handling of edge cases, and alignment with intended use while considering ethical implications.
How do you integrate testing into DevOps and CI/CD pipelines?
We implement multi-layered testing throughout the CI/CD pipeline, including unit tests during commits, integration tests during builds, and automated acceptance tests before deployment. Our approach ensures quality gates at each stage while maintaining delivery speed. We work with tools like Jenkins, GitHub Actions, GitLab CI, and Azure DevOps to integrate seamlessly with existing pipelines.
What testing tools and frameworks do you use?
We’re tool-agnostic but have expertise across numerous testing technologies, including Cypress, Playwright, and Selenium for UI automation; JMeter and K6 for performance testing; Postman for API testing; and specialised tools for accessibility and security testing. Plus more.
We select tools based on your technology stack, team expertise, and specific project requirements rather than forcing our preferred solutions.
How do you approach mobile application testing?
Our mobile testing strategy addresses the unique challenges of mobile apps through device compatibility testing across multiple devices and OS versions, performance testing under various network conditions, security testing for mobile-specific vulnerabilities, and usability testing that considers mobile interaction patterns. We utilise both real device testing and emulators/simulators depending on testing needs.
Can you help us transition from manual to automated testing?
Yes, we specialise in helping organisations gradually implement test automation. We begin by assessing your current testing processes, identifying high-value test cases for automation, developing a tailored automation framework, and training your team. Our approach focuses on sustainable, maintainable test automation that delivers long-term value rather than quick fixes.
