IoT Interoperability Testing
The essence of the Internet of Things (IoT) lies in the connection between people, processes, and things. However, it covers a vast area including all industries and consumers. The main challenge remains to ensure a hassle free interoperability between each connection.
Going by the definition, interoperability is required by the IoT system to get the full potential through seamless programmability. In order to ensure this, there needs to be a standard to connect diverse platforms irrespective of their manufacturer and industry. The vision is to have connectivity between people and processes. However, in reality IoT still lacks interoperability and is fragmented. Some of the concerns related to this, include the following.
- Devices that are made by different manufacturers cannot be integrated
- Not able to run on the same operating system
- Devices that are purchased at different times
- Different connectors and frameworks
- Different standard for communication protocol
- Lack of programmability
Adding to the existing challenges, technology giants like Google, Apple, Microsoft, etc. have to create interoperability. However, companies like Google and Apple have their own Internet of Things and therefore the challenge to some extent is underscored. These companies are creating a vertical stack of products instead of creating horizontal infrastructure, thus making it more fragmented.
Mass customization of IoT still remains a challenge, as many new vendors still look for interoperability. Though many things can interact, interoperability still remains a challenge, especially in the early phase, which remains chunky.
With more open-source frameworks in development, more and more companies are emerging to enable interoperability. However, there needs to be a proper IoT interoperability testing to ensure the seamless function of the IoT system. The following scenarios are tested using interoperability testing.
- Test the system from one manufacturer with other
- Test the entire system and the sub-system
- Test IoT devices with WLAN and LTE compliance
Interoperability Testing Characteristics
- Testing boundaries specified by the equipment being tested and qualified equipment
- The EUT and QE must be from different vendors and line of products
- Tests are conducted at interfaces that are used for monitoring
- These are functional tests as used by the user
- Interfaces like MMIs are simulated for interoperability
You need to develop interoperability tests before the test begin. You need to follow the below procedure.
- Specify abstract architecture
- Prepare Interoperable Features Statement
- Specify Test Suite Structure
- Develop Test Purpose
- Develop Test Cases
- Validate the TCs
- Finalize the Interoperable Features Statement
