Describe the scope of work in detail. Please include a summary of key deliverables.

"Testerly didn't just do basic testing; they really dug into our system to understand every detail of the payment flow. They built a custom framework using Playwright for End-to-End (E2E) testing of critical paths, including user onboarding and cross-border transaction processing. A huge part of their work was the API security validation of our bank connections via Postman to ensure a rock-solid integration. They also used JMeter to run heavy stress tests, which was essential for our DevOps team to properly scale the servers for high traffic. Instead of just manual reporting, they used n8n to automate the feedback loop between QA and development, making sure every issue was tracked and resolved without slowing us down. By the end, they delivered a full suite of automated tests that run with every code update, along with detailed performance audits and a clear strategy for our future quality control."

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

The most important result was a completely stable launch with zero critical issues in the live environment. By automating the most repetitive tasks, Testerly cut our manual testing time by about 40%, which let our developers move much faster. Their stress testing was also a huge success—they helped us find and fix several performance bottlenecks, confirming the system could easily handle over 5,000 concurrent users, giving us full confidence in our platform’s stability during peak transaction windows. Overall, they transformed our QA from a slow manual process into a reliable, automated system that gives us full confidence in every update we ship.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

We had a great experience with their team. Communication was always clear through Slack, and we never had to worry about missed deadlines. They were incredibly helpful and quick to respond whenever we needed to tweak something. Instead of just sticking to a fixed plan, they were flexible enough to change focus whenever our development priorities shifted.
