Testing Open Banking APIs: A QA Checklist for UK Fintech
A practical nine-part open banking API testing checklist for UK fintech QA teams: consent, SCA, payments, security, performance and compliance.

I’m a Software Test Engineer with experience working across different projects and domains, with a focus on delivering reliable, high-quality software. My work includes manual and functional testing, API testing, performance and load testing, accessibility testing, and test automation. I have worked on web, mobile, financial, and e-commerce projects, covering areas such as API validation, end-to-end functional testing, Shopify theme testing, and performance testing. I use tools and technologies including Postman, Apache JMeter, k6, Playwright, Cypress, Selenium, Appium, Java, JavaScript/TypeScript, and Groovy. Through this blog, I share practical experiences, testing approaches, automation solutions, performance testing learnings, and troubleshooting tips from my day-to-day work as a Software Test Engineer.
