According to Forbes, "the global IoT market can grow from $157B in 2016 to $457B by 2020, attaining a Compound Annual Growth Rate (CAGR) of 28.5 percent."

Adoption of IoT (Internet of Things) is increasing across various industries, in government sectors, and in consumers’ day-to-day life. Moreover, the enterprises are rapidly migrating or developing and rolling out their IoT-enabled apps into the mobile app market. And we already experience how the data generated by connected devices help businesses gain insights into business processes, take real-time decisions, and run more efficiently. For consumers, access to such information keeps them informed about the status of households, health and fitness, vehicles, and family members. It is fascinating to watch how these ‘smart devices’ interact with one another to provide a seamless experience of our embedded future.

Every quarter, the expected number of IoT devices is increasing enormously, and consumer expectations in terms of technology, user interface, and product quality are also rising fast.

IoT has given a new dimension to embedded systems. Previously, these systems worked in isolation. But with the evolution of IoT, connected devices now have to communicate well with each other to work properly. So delivering a high-quality product is very important, and thorough end-to-end testing becomes critical. This means the demand for better testing tools and more sophisticated testing models will increase in the connected world. Proper testing is a key to deliver error-free IoT-based application. Although manual testing will still happen, “test automation” has become a necessity for modern quality assurance.

Challenges Associated With Manual Testing for IoT Applications

IoT system comprises three modules: the connectivity module, the cloud, and the mobile app for end users to interact with the device, which is often developed in parallel. It is critical to manually test individual components for performance, reliability, interoperability, and security during the integration process and also identifying and addressing potential problems. For example, there are 15 different connectivity modules and two serial interfaces for each, which makes 30 various combinations. Each connectivity module has to be validated by about 1,000 test cases, which means 30,000 tests for a full release. Without automation, this task would be impossible.

Let us understand how automated testing can be beneficial for IoT applications. Unlike other testing methods, the process of automating testing is imperative to its success. Virtualization of an IoT ecosystem and using simulators, which can easily mimic the network of nodes, inherent to IoT, leads to faster turnaround and reduced hardware costs.

Test Automation Benefits to IoT Application Testing

1. Accelerate Automated Testing

  • Remove resource constraints and bottlenecks by virtualizing your devices
  • Enables continuous testing of apps with speed and agility
  • Allows parallel test execution on multiple devices

2. Improves Test Coverage

  • Cost effective testing supports various app versions, mobile devices and OS’s
  • Scalable virtual labs to support more test flows
  • Better ROI by a reduction in UAT defects and production defects
  • Defect prevention at early stages of the project life cycle

3. Fix Defects Faster

  • Get instant feedback on code changes
  • Repeatable automated tests execution simplifies debugging
  • Quickly resolves failing conditions from complex end-to-end tests

4. Faster Delivery and Higher Quality

  • Broader test coverage and fewer defects released to production
  • Reduced risk and faster release cycles through earlier functional and load testing
  • Lower costs related to complex test environment management
  • Reduces time to market by validating builds faster

5. Increased Testing Productivity

  • Assist in the generation of automated test scripts that are repeatable and extensible
  • Runtime analysis alongside live tests can easily detect and trace errors to be fixed
  • Automation can perform regression tests which ensures system stability while enhancing the application continuously.

6. Removing Hardware Resource Bottlenecks:

  • Accurately simulates the behavior of the actual component
  • Elimination of time and access constraints for dependent components and services
  • Parallel execution of functional or performance testing
  • Eliminates the requirement for access to constrained business-critical infrastructure, third-party systems, or cloud components for testing

7. Practical and Realistic Performance

  • No manual operation and physical maintenance increases efficiency and quality of testing
  • Cost-effectively and quickly test the performance of the connected device and the application that controls it

In a Nutshell

There’s no doubt about the fact that we are living in the IoT era. And, IoT applications can offer tremendous benefits to both end-users and developers, but adding connectivity to devices is no easy task. Businesses still need to be cautious as IoT brings a myriad of security risks. The role and future of IoT testing are, therefore, critical because it involves testing of hardware and software, transmitting massive amounts of real-time intelligence, which significantly reduces time to market, mitigate risk, and ensures ROI as per enterprise needs and priorities.
