An embedded system is a programmed hardware device which performs some dedicated tasks. Few of the possible challenges that might occur to perform automation testing on such systems are as follows:
Emulators/Simulators are used to perform automation testing in real time embedded systems. We face following challenge in this:
Probable Challenge 1: Emulators and Simulators may not accurately represent the behavior of the actual device and could though a false sense of application's usability and system performance.
Possible Solution: In such cases, the emulators and simulators should be evaluated for accuracy based on actual system.
Probable Challenge 2: Automation testing in embedded system may become complex due to complexity of software development in which changes in hardware and software interfaces are common.
Possible Solution: Modular and extensible automated test environments can significantly reduce the influence of these changes. For this is mandatory to put the efforts for a fair design and continuous maintenance.
Testing is considered as an art that makes the life of Software easier and secure. With the advancement of technology and needs of the mankind, the term software has become sophisticated and complex with each passing day. Belonging to the same pool of advancements are the Embedded Systems.
So, with such complex mechanical and electrical systems embedded within a software, quality is âtheâ factor makes up the profitability of the system. Ensuring quality to these systems is acceptably challenging; but not a rocket science. We have got Automated Frameworks that have created a âWoWâ factor in enhancing the quality details to these systems. However, it is very important to note the challenges that one has to overcome to in achieving this success. This article deals with some of such challenges in test automation for an Embedded Systems.
First and foremost, let us look at a few approaches and their challenges that deal in test automating the embedded systems:
1) Testing the IDE by Unit Testing.
2) Testing the Back end via Internet.
3) Testing against the Emulators and Simulators.
All said and done, every technique has got its own pros and cons. It is completely up to us on how to challenge these challenges to better the standards of the Embedded Systems. With the proactive intent amongst the testing world, it is expected that these challenges can be solved and we can expect to see better software testing frameworks helping to automate the Embedded Systems.
There are many challenges that one can face while implementing test automation on embedded systems. Basic challenges that surface are because of the complexity, which arises from the different combination/permutations of input and also, due to the configuration of the system.
Interoperability, connectivity issues and dependency on emulators and simulators can also pose a major challenge to perform automation testing as the final product is also developed in parallel with simulators and emulators. Another challenge that automation testers face is the lack of application programming interfaces (APIs) that are needed to drive the automation scripts.
To overcome such challenges we can use the automated the automated test cases to run scripts on emulators and simulators. This enables automation to be implemented on embedded systems at an early stage of development cycle. Also, this eliminates the dependency on hardware and interface.
Continual maintenance and careful design also prove beneficial in overcoming challenges of test automation on embedded systems.
