Overview

Due to the adoption of various technology trends such as remote monitoring and control, connectivity protocols, smart sensors, touch screen displays and so on; the embedded devices becoming more and more ‘smart & connected’. These smart embedded devices provide a lot of features and functionalities to bring usability, scalability and upgradability. This has resulted into ever increasing complexity of these devices; especially when it comes to testing phase.

Embedded device manufacturers have been looking for automated test framework to effectively address the complexity in testing phase and achieve full test coverage, high quality and time to market.

SoftDEL has extensive experience and expertise in testing of embedded devices within building automation, industrial and process automation, smart lighting, oil and gas and automotive domains. We have an in-house developed test automation framework for testing of embedded devices. This framework is embedded device agnostic and supports different testing types including regression, functional, integration, system, acceptance, smoke testing.
