Case Study — Transportation / eTolling
Client: Reputed eTolling & RUC App Startup, USA | Category: Mobile, Web & API Automation
Our client is a reputed US-based eTolling and Road User Charging (RUC) startup pioneering smartphone-driven toll payment technology. Their innovative platform eliminates the need for drivers to stop at toll booths by enabling seamless toll collection via a mobile app. The solution integrates native Android and iOS applications, a web management portal, and a suite of backend REST APIs — delivering end-to-end capabilities for toll tag management, vehicle registration, real-time location tracking, and in-app digital payments for commuters across the United States.
Build a comprehensive end-to-end test automation suite covering native mobile apps (Android & iOS), a web portal, and backend REST APIs — delivering consistent quality across all three platform layers of the eTolling ecosystem
Functional validation of critical user journeys including new user onboarding, GPS-based location tracking, toll tag registration and management, and in-app mobile payment workflows for road user charging
REST API test automation covering all critical endpoints — including user authentication, vehicle registration, payment gateway transactions, and automated toll deduction — with positive, negative, and boundary test scenarios
Integrate automation suites with CI/CD pipelines using Jenkins and GitHub Actions for automated nightly regression builds — enabling early defect detection and faster time-to-market for new eTolling features
Cross-device and cross-browser compatibility testing across a wide range of Android and iOS devices, screen resolutions, and OS versions to ensure a consistent user experience for all toll payment app users
Four technically distinct layers — Android, iOS, web, and API — had to behave as one reliable system, with location data and payment logic that are inherently hard to test.
Orchestrating a unified, maintainable test automation strategy that delivered consistent regression coverage across three technically distinct platforms — Android mobile, iOS mobile, web portal, and backend REST APIs — without siloed testing efforts.
Simulating and validating real-time GPS geolocation data and dynamic toll deduction logic within automated test environments — a technically complex challenge inherent to location-aware RUC and eTolling applications.
Thoroughly validating payment gateway integrations for digital toll transactions — including successful payment flows, declined transactions, partial payments, and timeout edge cases — in a zero-tolerance financial processing environment.
Enforcing rigorous API payload schema validation, HTTP status code accuracy, and response time benchmarks across frequently evolving and dynamically structured REST API endpoints of the toll management backend.
Thoughtcoders built dedicated automation for each platform layer, then unified them under one CI/CD pipeline so every commit was validated end to end — mobile, web, and API together.
Developed robust Appium-based mobile test automation scripts for both Android and iOS platforms, covering end-to-end user journeys including new user onboarding, GPS location tracking, toll tag management, and in-app digital payment processing.
Engineered a scalable and maintainable Selenium WebDriver web automation framework using the Page Object Model (POM) design pattern — enabling modular test scripts, reduced maintenance effort, and faster test authoring for the eTolling web portal.
Designed and executed comprehensive REST API test cases using Postman and Newman, incorporating JSON schema validation, response body assertions, status code verification, and automated collection runs within the CI pipeline.
Integrated mobile, web, and API automation suites with Jenkins and GitHub CI/CD pipelines — enabling continuous automated testing on every code commit and delivering real-time quality feedback to development and product teams.
Executed cross-device compatibility testing across real Android and iOS devices via BrowserStack's cloud testing infrastructure; generated detailed Allure and Extent Reports for full test execution traceability and stakeholder visibility.
Sustained high regression test coverage across all sprint cycles by actively participating in agile sprint planning, automation backlog grooming, and retrospective reviews — ensuring test automation continuously evolved in lockstep with new eTolling features and product releases.
A stop-free tolling experience only works if every layer behind it — GPS tracking, payment processing, vehicle registration, and cross-platform apps — is validated together, not in isolation. By building dedicated automation for Android, iOS, web, and APIs and unifying them under one Jenkins/GitHub CI/CD pipeline, Thoughtcoders gave the client one consistent signal for release readiness across the entire ecosystem.
Treating the payment gateway as a zero-tolerance surface — testing declines, timeouts, and partial payments as rigorously as the happy path — meant financial edge cases were caught before they ever reached a commuter's toll account.
"A tolling app has no room for 'mostly works' — a missed GPS ping or a silent payment failure becomes a driver's problem instantly. Testing every layer together is the only way to earn that kind of trust."
