OCR Testing in Mobile Applications

Overview

OCR Testing in mobile applications focuses on validating the accuracy, reliability, and performance of text recognition from images on real devices. It ensures that the app accurately detects and extracts text across different fonts, languages, lighting conditions, and image quality. By testing OCR on physical devices, teams can uncover issues related to image resolution, orientation, and regional language support that are often missed in emulators. This helps ensure consistent text recognition for use cases such as document scanning, ID verification, receipts, QR alternatives, and app data captured across diverse devices in real-world conditions.
