Its hard to elucidate about embedded systems especially when you try so hard to do so considering you always encounter them at home, in the office, or everywhere. The embedded systems have certainly infiltrated our daily lives and makes up almost 90% of the value of these devices that we regularly take for granted. Testing embedded system could be required to be sure that using such device is safe and that its performance can better improve daily activities. This can also be a necessary step for corrective and preventive measure intended for improved quality. With testing of the embedded systems, the devices can be debugged or removing defects. It is the job of the software creators to debug these devices so they will become more productive and their performance is optimized. Testing embedded systems comprises an actual evaluation of the application including some of its components as against a criterion. The testing is done based on the behavior, robustness and performance which can be measured and validated very easily. The testing process ensures good quality of product while it is still being developed. Functional testing, however, is another type of testing which differs from embedded systems testing since functional testing or also called black box testing, is done according to the specs of software components. It involves five steps that are the identification of the various functions that the software will perform, the creation of an input data based upon the specifications of the function, the determination of the output based upon the function specifications, the execution of the test and finally the comparison between the actual and the expected results. Embedded systems are also present in medical, nuclear and the avionics industry that it's therefore significant to undergo the testing in order to safeguard safety and quality. Prevailing standards should be followed for the development of such software in avionic industry since they are important for excellent performance as well as to save lives. Similar criteria is being observed for testing embedded systems in transportation as well as medical industries because both are important for the safety of human lives. If the software is not tested for quality and performance the effects might result to a system failure or a catastrophic failure of the whole system. This is the rationale behind testing embedded systems which should meet all the mandatory requirements for all levels of equipments and devices.
