    ??Module testing (or unit testing) is a process of testing the individual subprograms?? subroutines?? or procedures in a program. That is?? rather than initially testing the program as a whole?? testing is first focused on the smaller building blocks of the program.??
???Pragmatic Unit Testing in C Sharp with NUnit?????У???????????????￡?

      ??A unit test is a piece of code written by a developer that exercises a very small?? specific area of functionality of the code being tested. Usually a unit test exercises some particular method in a particular context. For example?? you might add a large value to a sorted list?? then confirm that this value appears at the end of the list. Or you might delete a pattern of characters from a string and then confirm that they are gone.
      Unit tests are performed to prove that a piece of code does what the developer thinks it should do.??
