How to skip a BOOST unit test?

Question

How can I skip a BOOST unit test? I would like to programatically skip some of my unit tests depending on, (for instance) the platform on which I am executing them. My current solution is:

#define REQUIRE_LINUX char * os_cpu = getenv("OS_CPU"); if ( os_cpu != "Linux-x86_64" ) return;

BOOST_AUTO_TEST_CASE(onlylinux) {
    REQUIRE_LINUX
    ...
    the rest of the test code.
}

(note that our build environment sets the variable OS_CPU). This seems ugly and error-prone, and also like the silent skips could cause users to be skipping tests without knowing about it.

How can I cleanly skip boost unit tests based on arbitrary logic?

Answer 1

BOOST_AUTO_TEST_CASE(a_test_name,*boost::unit_test::disabled())

{
   ...
}

Answer 2

Use enable_if / enable / precondition decorators.

boost::test_tools::assertion_result is_linux(boost::unit_test::test_unit_id)
{
  return isLinux;
}


BOOST_AUTO_TEST_SUITE(MyTestSuite)

BOOST_AUTO_TEST_CASE(MyTestCase,
                     * boost::unit_test::precondition(is_linux))
{...}

precondition is evaluated at runtime, enable, enable_if at compile time.
