The CMakeOnly directory added by commit9a20abf0(Add infrastructure for CMake-only tests, 2012-01-11) was sufficient only for tests that always run CMake to successfully configure a project. Later commiteeaaffcb(find_package: Test error and warning messages in failure cases, 2012-02-28) added a sample test that covers failure cases. Generalize the above to create new "RunCMake" test infrastructure that can run CMake multiple times for a single project with different variations and check for expected result/stdout/stderr. Allow for both successful and failing CMake project configuration cases. This will be useful to test error messages and failure behavior.

If you think about adding a new testcase then here is a small checklist you
|
|
can run through to find a proper place for it. Go through the list from the
|
|
beginning and stop once you find something that matches your tests needs,
|
|
i.e. if you will test a module and only need the configure mode use the
|
|
instructions from section 2, not 3.
|
|
|
|
1. Your testcase can run in CMake script mode, i.e. "cmake -P something"
|
|
|
|
Put your test in Tests/CMakeTests/ directory as a .cmake.in file. It will be
|
|
put into the test binary directory by configure_file(... @ONLY) and run from
|
|
there. Use the AddCMakeTest() macro in Tests/CMakeTests/CMakeLists.txt to add
|
|
your test to the test runs.
|
|
|
|
2. Your test needs CMake to run in configure mode, but will not build anything
|
|
|
|
This includes tests that will build something using try_compile() and friends,
|
|
but nothing that expects add_executable(), add_library(), or add_test() to run.
|
|
|
|
If the test configures the project only once and it must succeed then put it
|
|
into the Tests/CMakeOnly/ directory. Create a subdirectory named like your
|
|
test and write the CMakeLists.txt you need into that subdirectory. Use the
|
|
add_CMakeOnly_test() macro from Tests/CMakeOnly/CMakeLists.txt to add your
|
|
test to the test runs.
|
|
|
|
If the test configures the project with multiple variations and verifies
|
|
success or failure each time then put it into the Tests/RunCMake/ directory.
|
|
Read the instructions in Tests/RunCMake/CMakeLists.txt to add a test.
|
|
|
|
3. If you are testing something from the Modules directory
|
|
|
|
Put your test in the Tests/Modules/ directory. Create a subdirectory there
|
|
named after your test. Use the ADD_TEST_MACRO macro from Tests/CMakeLists.txt
|
|
to add your test to the test run. If you have put your stuff in
|
|
Tests/Modules/Foo then you call it using ADD_TEST_MACRO(Module.Foo Foo).
|
|
|
|
4. You are doing other stuff.
|
|
|
|
Find a good place ;) In doubt mail to cmake-developers@cmake.org and ask for
|
|
advise.
