This section describes rules how the functionality of the IT++ library should be verified. In the
`tests' subdirectory test files are provided. All functionality should be tested using these test files.
Each new IT++ module/class should be accompanied with a test file. The test file is an implementation in C++ that tests the functionality of a function/class or a group of functions/classes called modules. The test file should test relevant parameter settings and input/output relations to guarantee correct functionality of the corresponding classes/functions. The test files should be maintained using version control and updated whenever new functionality is added to the IT++ library.
The test file should print relevant data to a standard output that can be used to verify the functionality. All relevant parameter settings should be tested.
The test file should be placed in the
`tests' subdirectory and should have a name ending with
Consider a test file named
`module_test.cpp'. A reference file named
`module_test.ref' should accompany the test file. The reference file contains a reference printout of the standard output generated when running the test program. The reference file should be maintained using version control and updated according to the test file.
One can compile and execute all test programs from
`tests' subdirectory by typing
% make check
after successful compilation of the IT++ library.
