Case Study Summary
How did Clear Sky accelerate quality for NY E-ZPass's TollsNY platform?
Clear Sky embedded its Stratos platform across both API and customer-portal validation for NY E-ZPass's TollsNY tolling platform, using an API-first approach to begin testing before the portal was complete.
In under 60 days it achieved 92% test coverage with 450+ automated test cases, validating thousands of account, vehicle, and payment combinations to strengthen release readiness for a high-volume public tolling system.
Outcomes at a Glance
The Challenge
Modernizing a Mission-Critical Tolling Experience
NY E-ZPass needed to modernize the digital experience supporting toll account management for New York commuters. The new TollsNY platform required both a robust API foundation and an intuitive customer-facing web portal. Because the platform supported high-volume tolling transactions and customer account activity, quality could not wait until the end of development. NY E-ZPass needed a way to validate backend services, business rules, data conditions, and customer-facing workflows — in parallel with active development.
