[Insight-developers] CMakeLists changes

[Bill Hoffman]

OK, but there is no way to enforce that developers turn on the testing.

How about this...

The current problem is that ITK builds too many .exe files.
In VTK this is not a problem because the majority of the tests
are written in Tcl, so there is one executable vtk.exe that is used
to run all the tests.   

What if for each library :
Algorithms Common Local Patented BasicFilters IO Numerics

We created a TestDriver exe program.  It would compile all of the
tests for that directory into one executable, allowing shared template
instances to be combined into the exe file.   It would take a command line
argument that was the name of the test to run.   We could take all
the existing tests and just change the name of main to the name of the test.
And add a register step in the TestDriver.cxx main.

For example:

itkAlgorihmsTests.cxx:

std::map<std::string, mainfuncpointer> TestMap;
#define ITK_REGISTER_TEST(test) \
extern int test(int ac, char** av); \
TestMap[##test] = test; 

void RegisterTests()
{
  ITK_REGISTER_TEST(itkBinaryMinMaxCurvatureFlowImageFilterTest);
  ITK_REGISTER_TEST(itkCurvatureFlowTest);
}


main(ac, av)
{
  RegisterTests();  // create test map strings to function pointers
  return (*TestMap[av[1]])(ac, av);  // run the test from the command line
}


The downside would be that if one test failed to compile, none of the
tests would run.  However, that is the same situation that you have in
VTK, if Common does not build, non of the tcl tests are run.

This might be a better way to manage C++ tests.
