nit testing improves programming productivity and improves object oriented class abstraction. classes should be loosely coupled and their methods should do exact what they describe. Unit testing help isolate the functionality of the class. classes and derived class functionality can be access by type casting. Virtual and override methods will have predictable behavior that can be verified in unit testing. Unit testing should be built as you go. Refactoring classes and methods will affect the unit tests, but often don't take long to correct. Unit testing promotes better abstraction reducing complexity and makes possible more reusable components. The automated unit testing can be run every night after checkin and a report generated for correction the next day. Legacy systems, code and design can be refactored incrementally. The real value of unit testing is design feedback. Unit testing reduces fear and increases understanding of the object interface and interaction behaviors. I often look at the unit test to see how to use the application. Every developer is responsible for his code and the code quality of others. github is an excel resource of collaberating with other developers to build quality code. unit tests are a standard expectation of the github repository. Unit test should on test one path. Visual Studio Manager has an unit test manager providing automatic test runs or debug test runs. You can see quickly the quality of your solution by running your unit tests.[Learn More ...]
