Things to consider for testing IoT based projects

What is IoT and how they are Useful?

IoT's are the network of embedded items like sensors, electronics software, actuator and other physical objects which collectively exchange data.

Some of their major application areas are as irrigation, homes, offices, education and even healthcare departments, they facilitate user with improved efficiency, better sensing and reduced cost

How IoT based project can be tested?

This is a multiple layers architecture which needs a different type of testing at each layer

Let's review the layers and testing required for each:

1) Data sensing layer: this consists of actual devices like sensors, RFID(s), wearables, etc which are connected by various protocols to communicate with each other.

Testings required in this phase: IOT device testing to check whether the device is acquainted with features which we need to measure, hardware testing & edge testing will be the parts here to consider

2) Data transfer layer: this layer works as a data sending layer which includes routing and addressing, network collaboration, error detection in data transportation, acknowledgments. even after that multiple protocols and differently versioned networks may work together for the collection of data where latency should be avoided as much as possible.

Testings required in this phase: here we will be testing the data transfer protocols used with the acknowledgments

3) Data processing layer: This layer can also be named as the service layer which holds all the decision-making algorithms, monitoring all incoming data, visualizing and organizing all information.

Testings required in this phase: performance testing and all algorithms which are changing data from one form to another must be tested to avoid any type of data loss

4) Application support and management: This layer is for management and support purposes for application, by converting in the observable and visual manner we have the data but who all can access the data is a big question, here we manage authentication, identity management, etc

Testings required in this phase: All type of security testings must be provided here for the authentication because the application may contain classified data which should not be open to all

5) Application layer: This is the highest level layer of architecture and is a way of representing all the collected data in various forms like tabular, charts, etc.

Testings required in this phase: all type of functional and non-functional testing should be performed here to ensure the user gets the all possible requirements he needs.

A Final Note:

IoT is a new time vertex of Software/IT of the business. The market requests and ascent of innovation, associations are intending to fabricate and moving to IoT items to extend their associated environments.

To test the IoT applications different techniques comes nearer from our standard QA rehearses setups require for an IoT. The three IoT center parts viz Devices, Communication Between the gadgets and figuring the measure of information that should be handled and investigated.
