Mobile Test Automation for Banking App
Cross-platform automation framework for critical banking flows on Android and iOS
Overview
A banking application needed reliable automated regression across Android and iOS. The app combined native UI, hybrid webview screens, and multi-step authentication — creating real challenges for automation stability. This project involved designing a test framework from scratch, with a focus on maintainability, cross-platform reuse, and CI/CD integration.
Challenge
Hybrid app architecture with native and webview contexts required careful handling of context switching during test execution.
Complex authentication flows (biometrics, OTP, session management) created flaky automation scenarios.
Frequent UI changes across releases demanded a framework designed for minimal maintenance overhead.
Cross-platform coverage needed to be achieved without duplicating the entire test suite for Android and iOS.
Approach
Designed a layered framework architecture: Page Objects for UI abstraction, service layers for API interactions, and a shared test logic layer that works across both platforms.
Implemented robust context-switching utilities for seamless native-to-webview transitions, with auto-retry and wait strategies for stability.
Created a dynamic element identification system combining accessibility IDs, XPath fallbacks, and platform-specific locator strategies.
Built data-driven test patterns allowing the same test scenarios to run against multiple environments and user profiles.
Integrated the framework with Jenkins pipelines for automated regression execution on every release candidate.

Outcomes
Achieved stable automation coverage for critical banking user flows across both Android and iOS.
Reduced regression testing cycle time by enabling parallel automated execution.
Framework architecture withstood multiple major UI redesigns with minimal locator maintenance.
Provided the team with clear, automated pass/fail signals integrated directly into release pipelines.
Summary
Mobile automation in banking demands architecture built for real-world complexity — hybrid apps, complex auth, constant UI evolution. This framework prioritised durability, and its layered structure held up across multiple major releases.
