Case Study Summary
How did Clear Sky transform QA for Orlando's SunRail and LYNX transit systems?
Clear Sky embedded its Stratos platform for continuous, in-development testing across Orlando's SunRail and LYNX transit ticketing and operations platform, delivering 7,000+ automated test cases in under three months.
This drove a 1,825× increase in testing capability, cut individual test execution from 25 minutes to about 90 seconds, and reduced the full regression cycle from six weeks to under one hour — stabilizing every release and restoring commuter confidence.
Outcomes at a Glance
The Challenge
Breaking the Cycle of Reactive QA
Orlando's SunRail and LYNX transit platform spans physical devices, customer-facing applications, and backend systems—requiring seamless coordination across a complex, multi-layered ecosystem. The team was trapped in a reactive defect loop, with successive releases compounding instability rather than resolving it.
System Landscape
How Clear Sky Helped
Embedding Stratos for Continuous, In-Development Testing
Parallel Automation with Defect Remediation
As teams addressed production issues, automation was developed in parallel—ensuring fixes were immediately validated and protected against regression without slowing delivery.
Real-Time Regression Expansion
The regression suite grew continuously alongside development, eliminating reliance on limited, static manual test cycles and ensuring coverage kept pace with every code change.
Full-System Integration Testing
Stratos enabled synchronized validation across all system layers—device APIs, web UI, REST & SOAP services, Excel reporting, S/FTP transfers, socket communications, and backend services.
High-Frequency Execution
Daily execution cycles replaced infrequent testing, providing constant feedback and rapid issue identification so the team could contain and fix issues in near real-time.
Scalable Performance Validation
The system was continuously tested under realistic conditions via cloud-based hyperscaling, ensuring readiness for real-world commuter demand—executing 7,000+ tests in under one hour.
