Testing is the most important part of software designing. All the software developed has to go through the various tests to insure that it will perform in the real world. It has to perform to all the set standards and requirements. All the results obtained from the software is very important to match the required results.
There are different types of testing that are carried out on a software, unit testing, system testing and integration are the three main tests carried out on a software. Software almost always develops bugs that will cause the system to crash. Once bugs are detected in the software, they are reported back to the development team finds these bugs out and remove them.
In embedded software testing, the rules are the same. The most efficient way of testing software is by the use of automation testing. The other processes of testing through unit and integration testing run into a long time and a lot of testers are required to do so. Many testing tools have been made available in the market which help simplify these processes. Although automation testing can not be applied in environments that run real time data. All testing tools are designed for use with particular software. If software needs to be tested, the testing tool has to be redesigned from scratch. The use of these tools is all up to the managers to decide if they are required or not. Manual checking is the client side of testing where the tester uses the software the way a client will. This will avoid any problems that come up while using these embedded software in the real world. Manual testers can never be replaced by automated testers, no matter how good they are, since it is humans who are eventually going to use the software.
