The reusability of previous verification efforts is an important parameter is assessing the “immediate” reusability of the code; in this paper, the verification technique that we are focusing on is software testing. Observations about Testing "Testing is the process of executing a program with the intention of finding errors." Software reuse can be more readily enabled if the testing of the code in the previous environment is still applicable to the new environment. This post is mainly focusing on describe the general specifications of software quality attributes. Agility in context of software engineering. A program is an executable code, which serves some computational purpose. In order to achieve a higher degree of testability, it has to be carefully considered right from the design phase throughout development. The appendix discusses other definitions of software testability in the literature. Testability is the extent to which a piece of software can be tested.

The only way to do exhaustive testing for a system like this would be to connect all the components and perform tests end-to-end if no test hooks were built for individual components which makes the fault-isolation very difficult. Testability should always be considered while signing and implementing a software system so that the errors (if any) in the system can be detected with minimum effort. Of course everything can be tested after a product is finished but is that needed and is it right to place all the tests at a stage prior to delivery is what needs rethinking. 1. This is determined by both aspects of the system under test and its development approach. This is why we give the book compilations in this website. Place a right set of test hooks at both the end. If the testability of the software artifact is high, then finding faults in the system (if it has any) by means of testing is easier.
