From Chaos to Coverage: The Architecture Behind the Test Recording Tool (TRT)
The Backstory: Hackathon Idea to QA Transformation
Picture this: a software development team trapped in endless hours debugging client test suites to unblock failing CI/CD builds. Deployments stall, frustration mounts, and morale suffers. At ProdPerfect, this was our reality. Software testing is crucial for ensuring new features don’t break existing functionality. We focus on the Golden Path—the critical user flows that must always work. However, manual test suites were a significant bottleneck. During an internal hackathon, I developed the Test Recording Tool (TRT), a Chrome extension and backend system that revolutionized our QA process by automating test creation and improving debugging speed.
The Chaos: Manual QA Grind
Before TRT, QA at ProdPerfect involved:
- Dynamic UI Complexity: Constant selector changes due to dynamic CSS frameworks caused frequent test failures.
- Hidden UI Elements: Crucial UI components were obscured behind multiple modals and conditional flows, wasting valuable engineering hours.
- Delayed Feedback: Engineers waited hours for test coverage reports, testing blindly and repeatedly, uncertain if they’d met requirements.
This cycle drained productivity and stalled deployments.
The Problem: The Painful Reality of Regression Testing
Imagine trying to conduct regression testing on a feature that is constantly changing. UI selectors shift with each new build, important buttons are hidden behind modals, and development environments don’t match production. That was the situation we faced.
Writing tests was difficult, and keeping them updated was even harder. The main challenges were:
- Dynamic UI: Selectors generated by dynamic styling frameworks like CSS-in-JS changed frequently, causing brittle tests.
- Vague Error Logs: Confusing error logs made it difficult to pinpoint the root cause of a failure.
- Time-Consuming Debugging: Fixing a single broken test could take hours or even days, creating significant deployment delays.
This process wasn’t just slow; it was exhausting and made our work harder than it needed to be. We needed a better way.
TRT Architecture: Engineering Clarity
TRT reshaped QA by automating the entire testing workflow:
- Dashboard-Driven Testing: QA engineers trigger testing sessions directly from an intuitive dashboard. Each session spins up an ephemeral EC2 environment running the client’s web application.
- Remote Interaction via VNC: Engineers remotely interact through a browser-based noVNC session, removing environment setup overhead.
- Comprehensive Session Capture: TRT records DOM interactions, screenshots, and videos. This data flows through an Express backend and is stored securely in an AWS S3 bucket.
- Real-Time Data Analysis: Captured data is instantly analyzed by a dedicated Data Service, validating tests against real user paths (the Golden Path), clearly highlighting coverage gaps.
- Instant Reporting & Integration: QA engineers immediately see comprehensive coverage results, eliminating guesswork. Validated test sessions automatically generate detailed Jira tickets, ready for immediate follow-up.
Collaboration and Iteration
Building TRT required constant collaboration with different teams: QA engineers, product managers, and data engineers. Their direct input ensured TRT precisely solved real-world pain points, evolving quickly from hackathon prototype to a critical system within our workflow.
The Coverage Impact: A 600% Improvement
The implementation of TRT transformed our QA effectiveness:
- Debugging and achieving test suite coverage dropped from 72 hours to less than 12 hours.
- Provided instant, clear test coverage visibility.
- Enabled teams to proactively identify and resolve issues through data-driven insights.
One client used TRT to swiftly pinpoint a dynamic selector issue during checkout—a process that previously took days. TRT’s efficiency became our new standard.
Lessons Learned
The development of TRT reinforced several valuable software engineering principles:
- Solve tangible problems first through user collaboration.
- Trust data-driven insights over gut instinct.
- Maintain simplicity, even when handling complexity.
TRT was not just a tool but a catalyst for a transformative shift in our QA culture.
Conclusion
TRT turned our QA grind into a glide, shrinking debug time from endless hours to a breeze and making test creation a data-driven snap. Encounter similar challenges or have insights to share? Let’s connect and innovate together.
