Testing and program analysis

Program analysis and testing go hand in hand to assure the quality of our solutions. For example, running Valgrind becomes more consistent when test code is used. For this reason, we'll configure those two things together. Figure 12.5 illustrates the execution flow and files needed to set them up (a few snippets will be added to the src directory):

As we already know, tests live in the test directory, and their listfile gets executed from the top-level listfile with the add_subdirectory() command. Let's see what's inside:

include(Testing)
add_subdirectory(calc)
add_subdirectory(calc_console)

Testing utilities defined in the Testing module are included at this level to allow both target groups (from the calc and the calc_console directories) to use them:
