End to End IoT Testing

End to End IoT Testing

In today’s technology driven markets devices, machines, and systems are getting connected. This makes business software having more and more data-driven features. IoT technologies are enabling the connectivity of these devices with the cloud. The users interact through mobile devices. Hence quality, security, and performance of embedded software are critical. 

The Internet of Things (IoT) is a network of physical objects (devices, vehicles, buildings, etc.) embedded with electronics, software, sensors, and network connectivity that enables data collection and exchanging of data. Achieving sufficient test coverage is challenging and requires considerable effort and time. A suitable test strategy is a must to address these challenges.   

An IoT Solution deployment has high technical complexity as a huge volume of data gets generated and transmitted over different connectivity layers, IoT applications and solutions demand a holistic approach in their testing. Some of the unique factors and challenges associated with IoT applications are: 

  • Dynamic environment: Unlike application testing in a defined environment, IoT has a very dynamic environment with millions of sensors & different devices used in conjunction with intelligent software.
  • Real-time complexity: IoT applications have multiple, real-time scenarios & its use cases are extremely complex.
  • Scalability of the system: Creating a test environment that simulates end devices, users, and interfaces that matches the system’s functionality, scalability, and reliability is challenging.
  • Other operational challenges: Related subsystems and components could be owned by third-party units. A complex set of use cases, diverse hardware, security, and privacy requirements makes the creation of test cases and test data challenging.  

Gadgeon’s end-to-end IoT testing services provide comprehensive quality management and test strategy for your IoT solutions. It comprises test management, test planning, test scenario identification, test environment management and execution of test cases – manually as well automated.  Both the functional and non-functional requirements like security, performance, stress testing, etc. will be covered.  We bring thought leadership by way of recommending and implementing process tailoring, guidelines, best practices, templates, and continuous improvements to the testing of IoT solutions. 

Test planning and data simulation: Metrics-driven exhaustive test execution and static code coverage analysis along with continuous integration and release cycles will ensure a stable high quality IoT system irrespective of the complexities involved. 

Embedded IoT Testing Areas


  • Gadgeon addresses the complexities and challenges of embedded IoT testing through a test strategy that focuses on Device Interaction as well as User Interaction layers. 
  • At the Device interaction layer, since the software and the hardware components interact in real-time, in addition to functional testing, types of testing like conformance with standards, interoperability, and security are required to be executed.
  • The User interactional layer acts as the touch-point between ‘Things’ and ‘User’. A seamless experience is critical. We conduct tests covering specific aspects of network communication, connectivity, usability, user experience, IoT services, and back-end environment.
  • The cumulative experience of 250+ man-years in embedded real-time hardware and firmware development of complex systems
  • We deliver consistently 40-50% cost savings and about 60% savings in schedule
  • Expertise and ability to bring thought leadership in the implementation of tools, process improvements, guidelines, best practices, templates, and process tailoring
  • Built in libraries to interact with DUT interfaces like serial (RS232/RS485/USB) and Ethernet (SSH/Telnet/HTTP, HTTPS)
  • Relay/Servomotor for simulating the power cycle / button press events
  • Light sensor module for validating the visual indications
  • Wireless sniffers and Protocol analysers for protocol/data validation
  • Voice conversion libraries for voice commands verifications
  • Appium/Selenium libraries for automating mobile / web applications
  • NMAP/OWASP plug-in for security and vulnerability analysis 
  • Jenkins/Bamboo/GitLab plug-in for enabling the CI/CD pipeline
  • Integrated with standard test management tools like TestRail /TestOpia.
  • Supports configurable options that support recovery in case of fatal errors in target devices
  • Built in libraries to deploy embedded/firmware/application images on target devices or environments
