Things You Should Know About IoT Testing

In the era of technologies, it is essential to keep up with the speed of the growing market. Now people are moving towards the emerging technologies, and Internet of Things (IoT) is one of them. IoT is an extensive technology which includes many use cases for IoT platforms and solutions. It offers some interesting applications to make our lives easier.

"Internet of Things (IoT) gets set to connect about 20 billion devices by the year 2020 according to Gartner."

With the increasing demand for IoT, software testing teams are refurbishing their testing techniques to keep up with this emerging tech. IoT testing requires a different environment and approach to execute testing strategies. Customers today are demanding quality output with speed. So, the need for automation testing has increased. Automation testing has also become one of the most important components of IoT testing. It is the most flexible and lightweight approach for IoT testing. It is said that test automation is challenged by IoT.

"The global IoT testing market is estimated to grow from USD 302.9 million in 2016 to USD 1378.5 million by 2021, at a CAGR of 35.4%, - MarketsandMarkets"

Challenges faced during IoT Testing

  • Connectivity Issues
  • Complexity
  • Safety Concerns
  • Power Issues
  • Quality Issues

Solution to these Challenges

  1. QA team should concentrate on best testing strategies and practices. These strategies should be designed based on the requirements; this will help in generating a quality output.
  2. There is a huge amount of data transferred through IoT devices, there are some IoT testing supported platforms that ensure efficient communication between the devices while data transfer.
  3. QA testing team should have enough knowledge of the OS, applications, architecture, and protocols to design better test cases.
  4. Organizations should have strong backend as it directly affects the output of the product.

As IoT is considered as one of the most trending technologies nowadays, IoT testing plays a very significant role as it unlocks the door for new business opportunities and strengthens enterprises to serve by new revenue streams, enhanced analytics, and reduction in human interference, efforts, and manual labor.

To ensure performance, adaptability and security of IoT applications, certain type of testing are endorsed:

1) Compatibility Testing
IoT architecture is a mixture of simple and complex architecture. It is important to test the compatibility of various browsers, operating systems and various versions. This will help testers determine if there are any compatibility issues hidden within different IoT network layers.

2) Security Testing
Security Testing is one of the most important testing parameters while implementing IoT. If the connected devices are not checked properly then it may leak the sensitive data and will affect the overall functionality of the system.

3) Scalability Testing
It is a testing technique in which an applications’ performance can be tested based on its ability to perform under extreme conditions such as time required to process several user requests.

4) Usability Testing
Devices vary in size, shape and various factors and many users use them with different perceptive. So, checking the usability of the device is essential. In this testing type, displaying, processing and transferring the data from one device to another is monitored.

5) Performance Testing
Factors such as multiple users at a time, bandwidth, packet loss, etc. are considered by testers during performance testing. This testing examines how quickly the data is transformed from one network layer to another.

A lot of log analysis and backend verification is required while doing IoT testing, since the devices may have displayed to show output i.e. Radar, GPS, Detectors.

Most of the testing happens in simulation mode that may not cover some cases which happens in real mode. Identification of real-time scenario is also the most important area that needs to be verified. Failure condition of each IoT device also needs to be accessed since these devices will have limited memory, processing power, etc. To perform IoT application tests, testers may require certain test cases, strategies and tools as their input and output required to carefully verify before the deployment.
