[CMake] Running tests

[Olivier Tournaire]

Hi all,

Maybe it is a simple question, but I really have no answer. So, hope you 
could help me.

Here is my directories tree :

|_ src __
|          |_ geometrie
|          |_ truc
|
|_ test __
             |_ geometrie
             |_ truc

In test, I have this CMakeLists.txt :

-------------------------------------------------------------------------------------------------
PROJECT (Unit_Tests)

ENABLE_TESTING()
SET ( ENABLETESTING ON )

# Necessite BOOST pour travailler
INCLUDE_DIRECTORIES( E:/librairies/boost_1_34_1 )
# Necessite CPPUNIT pour le framework de tests
INCLUDE_DIRECTORIES( E:/librairies/cppunit-1.12.0/include )
LINK_DIRECTORIES( E:/librairies/cppunit-1.12.0/lib )

# Inclusion des répertoires qui contiennent les tests à réaliser
ADD_SUBDIRECTORY( geometrie )
ADD_SUBDIRECTORY( truc )
-------------------------------------------------------------------------------------------------

Then, in test/geometrie, I have this CMakeLists.txt :

-------------------------------------------------------------------------------------------------
PROJECT (Droites_Test_Project)

SET(DROITES_SRC ../../src/geometrie/Droites.cpp
                Main_Test_Droites.cpp
                DroitesTest.cpp)
SET(DROITES_INCLUDE ../../src/geometrie/Droites.hpp
                    DroitesTest.hpp)

ADD_EXECUTABLE(Test_Droites ${DROITES_SRC} ${DROITES_INCLUDE})
TARGET_LINK_LIBRARIES(Test_Droites cppunit.lib )

IF( ENABLETESTING )
    ADD_TEST(Droites_Test Test_Droites)
ELSE( ENABLETESTING )
ENDIF( ENABLETESTING )
-------------------------------------------------------------------------------------------------

Finally, in test/truc, I have this CMakeLists.txt :

-------------------------------------------------------------------------------------------------
PROJECT (Truc_Test_Projet)

SET(TRUC_SRC main.cpp)

ADD_EXECUTABLE(Test_Truc ${TRUC_SRC})
TARGET_LINK_LIBRARIES(Test_Truc)

IF( ENABLETESTING )
    ADD_TEST( Truc_Test Test_Truc )
ELSE( ENABLETESTING )
ENDIF( ENABLETESTING )
-------------------------------------------------------------------------------------------------


When I run CMake on the CMakeLists.txt which is in the test folder, I 
got a .sln with 4 projects : ALL_BUILD, RUN_TESTS, Test_Droites, 
Test_Truc. I am able to create executable binaries from the both lasts 
and then run RUN_TESTS which work.

However, I have no dependencies between Test_Droites, Test_Truc and 
RUN_TESTS, which means I have to build all projects to test before 
running RUN_TESTS. Is there a way to have only to build RUN_TESTS, in 
order to build the projects to tests and then launch the "tester" ?

Hope I am enough clear ...

Regards,

Olivier
