Want to Learn About Unit Testing?

   Software testing by definition is the process of evaluating a capability or attribute of a function, program or system and determining if it meets a required end result. The testing procedure itself will provide a reliable estimation of the systems quality assurance, validation and verification. Unfortunately there is a trade-off between reliability testing and the budget and time constraints placed on a project.

   Unit testing is the process where a block of code, usually a method, checks the validity and correctness of another piece of code. The validity of the output must be based on per-assumed values and any deviation from this would create a failed test.

   Unit tests themselves should be descriptively commented, repeatable and automated, simple to implement, simple to execute and fast in nature. The testing should follow an orderly progression in stages as you integrate different dependent modules and the dependency must be tested.

   Between code that no longer supported ‘legacy code’ to features that used to function ‘regression’ it can be a daunting task to design and implement flexible unit tests that still remain valid. Just remember to describe the unit test completely and keep the method short and simple.
