I need a reliable WebdriverIO + Appium test suite that runs the same functional checks on both iOS and Android. The focus is strictly on functionality: users must be able to log in and out, move around the app without hiccups, and complete a payment flow from start to finish. You’ll receive the current React Native codebase, sample user accounts, and a Git branch dedicated to automation. I’m looking for clean, page-object-style scripts, clear comments, and a single command that triggers the tests on an iOS simulator/device and an Android emulator/device. Deliverables • WDIO config adjusted for the two platforms • Page objects and specs covering login/logout, in-app navigation, and payment processing • A concise README showing how to set up dependencies and execute the suite locally and in CI Acceptance is simple: I clone the repo, follow the README, and the tests pass on both operating systems without manual tweaks.
