Today, the entire world is running on embedded software and
embedded systems are seen at every part of our daily life, be it the wireless
infrastructure behind the mobile handset, several systems in automobiles,
software-intensive systems in aerospace and defense, medical devices, consumer
electronics and so on. With the growing competition to deliver high quality
products with high-end functionality, most of the manufacturers across various
industries like automotive, aerospace, defense, consumer electronics, high-tech,
and medical devices are focusing on innovating new products by embedding more
and more software into them.
Most of the embedded systems are real-time and any defect or
compatibility problem can have a huge impact on enterprises. Many embedded products
developed like medical devices or systems developed for use in the Aerospace
industry can have a direct impact on the human safety and any failure in such
systems can result in costly re-work, delays, and even product recalls that can
have huge impact not only on the profits and success of new products, but also
on the over all brand image. For example, many global automakers in the recent
past have recalled their several car models over technical problems. General
Motors has recently recalled its Chevrolet Cruze cars from the North American
market due to steering and transmission problems while Honda Motor recalled its
certain models of Accord, Civic, Acura, and CR-V to rectify possible faulty
airbag defects. Hence, it is quite critical for manufacturers to develop
flawless embedded software to avoid such problems.
Embedded systems testing will help enterprises to meet the
demand for innovative, high-quality products, while at the same time address
safety-critical issues, time-to-market and cost pressures. It also plays a
crucial role to meet various statutory and regulatory requirements across
several industries. But, testing embedded systems is considerably more complex
than testing traditional software systems due to many reasons like, range of execution
platforms and cross-development environments, lack of clear design models, and
several quality and certification standards across various industries. To
ensure that the system's behavior, performance, and robustness meet the
expected criteria, embedded testing should include several major aspects like
unit testing and string testing of software across subsystems and integrated
testing of software across the entire product architecture, apart from system
unit testing, system integration testing, and system validation testing.
Unit testing is one of the most effective approaches to test
in the integrated development environment (IDE) as it ensures that all the
software units work as designed independently while system integration testing
verifies how different software systems work in combination. Test automation
can also be established to increase test coverage and ensure completeness and
efficiency. Testing against simulators or emulators can also provide
enterprises several benefits of software prototyping, test actual production
code, validate compatibility, and reveal many defects similar to testing on
actual device. Implementing various testing methods based on the requirements
of an organization and the type of the product, will ensure effectiveness and
efficiency of the test process, reduce development costs, and ultimately help
enterprises to deliver high-performing products.
