7 min readDec 14, 2022


The Internet of Things (IoT) is a constantly developing technology that is creating new opportunities in a variety of industries, and IoT solutions are also transforming cities. By 2026, the number of Internet of Things (IoT) devices will surpass 20 billion, according to Gartner.

As a consequence of innovation to boost sustainability and efficiency, IoT solutions have the potential to be infinite.

An IoT is a network of physical things, such as appliances, cars, gadgets, and other things, that are integrated with electronics, software, sensors, and network connectivity to store and exchange data over the internet. Some of these gadgets may be found in self-driving vehicles, smart houses, and other common household items like refrigerators and air conditioners.

IoT Quality Assurance may be used to verify the functioning of IoT devices because the behavior and performance of these IoT devices are largely governed by the quality of the embedded software applications and communications networks.

The Role of IoT Quality Assurance

Applications across a wide spectrum are being created to enhance the connected environment, which is already quite sophisticated. The network of home gadgets, vehicles, and medical equipment that employs embedded electronics and microchips to collect and exchange various forms of data is known as the “Internet of Things” (IoT). Because of this, testing for the Internet of Things involves analyzing software application code as well as confirming device connectivity services.

It is never enough to adjust with a set of merely working apps while validating an IoT service or system.

Sensors, apps, and gadgets, without a doubt, contribute to the ecosystem’s formation. Still, testing is required to validate the experience of apps in a dynamic context. There are many kinds of gadgets and sensors that provide the best experience when combined with intelligent software. Because of the complexity of IoT systems, it is not enough to merely confirm their functionality. IoT is also the most modern technology that gives businesses the ability to develop a broad range of systems, products, and services.

Implementing IoT projects in real-time is difficult. In addition to environmental settings, it also needs access to reliability and scalability to validate its correctness. Extensive simulation knowledge is needed to establish a test environment for the system, which is built on several analytics and engines. It is vital to use testing to solve the complexity of IoT QA because of the large amount of data (i.e., enormous volume, variety, and velocity).

How Can QA Testing Strengthen IoT Components?

It would solve a lot of problems if you asked BJIT to test IoT gadgets, and it’s possible that the IoT technology would be as advanced as that in Wakanda. However, the current practice is to test various systems separately.

The issue arises when data is transferred over the internet, even though some people may believe that the equipment that sends and receives data is properly tested, incredibly fast, and safe. To prevent a compromise during transport, this data must be encrypted.

Security, connection, analytics, network, processor, platform, operating system, and performance-related issues are all addressed by QA testers who evaluate IoT devices.

The common kinds of testing BJIT conducts are:

Controlling components

The Internet of Things is made up of parts that might interact to create a network and an IoT device. You need to test IoT components effectively, including hardware, software, connections, data flow, and the cloud. IoT components are independently tested to determine whether they can function effectively together and produce excellent results, and the complete system is evaluated by QA.

Usability evaluation

IoT devices could appear simple to create and maintain, but usability varies from device to device. It is unexpected, diversified, and intricate. Usability testing aids QA testers in confirming the device’s overall UX and usability. After all, the primary objective of product design for these gadgets is to be easily accessible.

Fast device connectivity, push notifications for successes or failures, transparency, clarity of all documented events, and data processing are a few examples of these accessibility characteristics.

Compatibility check

IoT devices employ a variety of software and hardware combinations, thus compatibility testing can be challenging. Significant data breaches or other connection problems might be caused by a hole or ineffective authentication. No matter the hardware or software being used, compatibility testing makes sure that the connection is reliable and secure across all devices.

Handling Exceptions

An IoT solution connects a large number of devices. While working on the complete system, certain unforeseen exceptions occur, and each component has distinct functions that must be properly monitored and addressed by quality assurance tests.

Performance Evaluation

The gadget functions effectively thanks to a personal setup. It is difficult to anticipate problems and defects when several IoT devices connect with one another, regardless of whether you are an experienced tester or a developer for an IoT software firm. Performance monitoring, which is a component of quality assurance and useful for understanding the effectiveness of IoT devices, is essential for ensuring that all IoT-based operations operate as expected and that the devices can connect with one another.

Testing for connectivity

A reliable network connection to the internet and other devices is necessary for IoT devices. QA engineers ensure that the system is constantly up and accessible, as well as that the connection and networking are stable. This area is critical because IoT data is often exchanged between devices, and such a connection is impossible without strong connectivity.

Security Checks

It is simple to transfer a lot of data via a shared network and to facilitate communication amongst IoT devices. IoT devices might lose sensitive and important data in the wrong place if the network has security breach problems. Because of this, security is crucial for IoT devices and quality assurance. Automated QA testing makes sure that every network and device is completely secure and protects the data from outside threats. Data encryption and decryption procedures must be confirmed through security testing in order to detect data loss and leakage, analyze data packets, and maintain system stability.

Challenges of IoT Testing

Due to the complexity of IoT devices and their interactions, it is difficult for QA testers to conduct tests as they would with a web application or software. Indeed, the essential tests should be carried out, minimizing the obstacles. Therefore, BJIT experts take care of the following cases before starting such a difficult task.

  • Internal and network communication are tested.
  • Complete reliance and continuous internet activities might lead to security risks.
  • Recognize that problems may be undiscovered due to sophisticated software or hardware settings.
  • Understand that memory, computing power, bandwidth, and battery life are all limited.
  • Network availability is a major determinant of IoT device performance.

Real-world Overview of Some IoT based Software Development Case Studies by BJIT

Traffic Motion Monitoring

The management of automotive traffic in large cities is made easier by the Internet of Things. We require the Internet of Things to display the circumstances of different routes, track traffic in real-time, and enhance information on different routes for the same distance, destination, and projected arrival time. Through applications like Google Maps or Waze, smartphones are utilized as sensors to gather and exchange data from moving automobiles. The aim of our study was to build models that accurately forecast how traffic agents would move around autonomous vehicles, such as automobiles, bicycles, and pedestrians.

Illegal Parking Identification

Numerous issues arise from illegal parking, including traffic congestion and dangers to other road users. Therefore, keeping an eye out for automobiles that have been parked illegally has become crucial to contemporary urban administration. An IoT-based solution has been created to automate the handling of illegal parking enforcement, offer real-time illegal parking analysis, and decrease the participation of human labor in on-the-spot verification of unlawful parking infractions.
