IOT Testing

Introduction

IoT – The Internet of Things is a digital network of physical objects which has embedded sensors that can collect, store and transfer data over a wireless network with no human intervention.

 

The 4 Key components of an IoT system are

1) Sensor

2)Application

3)Network

4)Backend (Data Center)

IOT is a connection of identifiable embedded devices with the existing Internet infrastructure. In simple words, we can say that IOT is an era of “Smart”, connected products that communicate and transfer a large amount of data and upload it to the cloud.

Testing for IoT devices broadly revolves around Security, Analytics, Device, Networks, Processors, Operating Systems, Platforms and Standards.

Types of Testing followed for IOT testing

Compatibility Testing

There are many devices which can be connected through the IOT system. These devices have varied software and hardware configuration. This leads to a huge possible combination and hence it is important to perform compatibility testing for the IOT system.

Usability Testing

There are numerous devices with different form factors with which the users interact. Usability testing refers to evaluating a product or service by testing it with representative users. The goal is to identify any usability issues, collect qualitative and quantitative data and determine the participant's satisfaction with the product. That is the reason checking usability of the system is important in IoT testing.

Data Integrity Testing

Checking the data for its integrity is crucial in IOT Testing as it involves a large amount of data and its application.

Reliability and Scalability Testing

Reliability and Scalability is the key to build an IOT test environment which involves simulation of sensors by utilizing virtualization tools and technologies.

Security testing (Non-functional testing)

In the IOT environment, there are many users accessing a huge amount of data. Hence, it is important to validate users via authentication, and have data privacy controls as part of security testing.

Performance Testing (Non-functional testing)

Performance testing is important to create a strategic approach for developing and implementing an IOT testing plan.

Following chart gives the applicability of different testing types for various components of IOT.

IOT Testing challenges

  • We need to check both the network and internal communication
  • Security is a big concern in the IOT platform as all the tasks are operated using the Internet
  • The complexity of the software and system may hide bug present in the IOT technology
  • Resource considerations such as limitations in memory, processing power, bandwidth, battery life, etc
  • Understanding the internals of the product
  • Lack of clarity in requirement specification.

Effective IOT Software Testing - Industry Standard Practices

  • Gray Box testing should be used with IOT testing as it allows the design of an effective test case. This permits you to know the OS, the architecture, third-party hardware, new connectivity and hardware device limitation.
  • Real Time Operating System is essential in delivering scalability, modularity, connectivity, security, which is important for IOT
  • IoT Testing needs to be automated after a couple of sprint releases as the product marches towards stability.
