Every Tap, Every Trip, Every Transaction — Tested
Modern transit systems run on dozens of interconnected platforms — the software behind fare validators, mobile apps, dispatch engines, payment gateways, and batch reconciliation systems. A failure in any one of them cascades. Stratos™ validates the entire chain, end to end.
Transportation Testing
How does Clear Sky test transit and tolling systems?
Clear Sky's Stratos™ platform validates the software behind fare collection and ticketing end to end — mobile ticketing platforms, the applications and APIs behind fare validators, dispatch and scheduling engines, payment gateways, and batch reconciliation systems.
It is capable of testing the systems behind the full fare-collection journey from mobile tap-in and fare calculation through overnight reconciliation — including tap-in/tap-out and smartcard flows — along with the systems that batch-process ridership logs, and simulates up to 25,000 concurrent users to validate APIs under peak transit load.
Built for Complex, Multi-System Transit Environments
End-to-End Journey Validation
Tests the full rider journey — from mobile tap-in through fare calculation, backend processing, and financial reconciliation.
Batch File Automation
Validates batch processing workflows — ridership logs, overnight fare reconciliation, eligibility files — via FTP/SFTP or custom endpoints.
Real-Time Data Flow Testing
Verifies data integrity between scheduling engines, rider-facing apps, and back-office platforms in real time.
Cross-Platform Test Chaining
Chains test suites across systems — trigger a test when a validator file drops, then verify the database, API, and dashboard outputs downstream.
Back-Office System Coverage
Supports mission-critical systems including payment gateways, operations dashboards, CRM platforms, and financial reporting tools.
Shared Test Environment
Brings business analysts, test developers, and automation engineers into one workspace — no silos, no handoffs, no duplicate effort.
Stratos™ Capabilities for Transit & Tolling
Fare System Stress Testing
Simulate thousands of real-world riders tapping in and out to run functional and load tests on fare collection and back-office settlement systems.
Batch Processing Validation
Generate randomized data files, submit them to your processing engine, and validate every transaction from intake to final report — automatically.
Real-Time Transit Data Verification
Validate live data flows between scheduling systems, rider apps, and back-office platforms — ensuring accuracy under normal and peak conditions.
Multi-System Test Orchestration
Chain tests across platforms so a single trigger validates the full pipeline: file drop → database update → API response → dashboard output.
Load Testing at Scale
Stress-test mobile ticketing, trip planning, and fare-collection systems with up to 25,000 concurrent simulated users across multiple regions.
API Validation Under Traffic
Verify that trip planning, fare, and payment APIs return accurate data — even during rush-hour traffic spikes.
Use Cases
End-to-End Transit Validation
Validate the full rider journey from the software behind fare validators through financial reconciliation — automated, repeatable, and auditable.
Report Reconciliation
Cross-verify simulated rider activity against backend operational and financial reports to confirm traceability and data integrity across your transit ecosystem.
Batch Processing for Ridership Logs
Generate randomized data files, submit them to your processing engine, and validate every transaction from intake through reporting.
Real-World Load Simulation
Stress-test mobile ticketing and trip-planning apps with up to 25,000 concurrent users from multiple regions to find breaking points before riders do.
API Validation Under Peak Load
Confirm that trip planning, fare, and payment APIs return accurate, timely responses — even under peak traffic.
