c++ - 具有夹具支持的 BOOST_DATA_TEST_CASE

Question

我正在 BOOST_DATA_TEST_CASE 中寻找夹具支持。我为它编写了以下 C++ 宏，但也许有人有更好的东西？

#include <boost/test/unit_test.hpp>
#include <boost/test/data/test_case.hpp>

#define BOOST_FIXTURE_DATA_TEST_CASE_IMPL( arity, test_name, F, dataset, params )  \
struct test_name : public F {                                                      \
    template<BOOST_PP_ENUM_PARAMS(arity, typename Arg)>                            \
    static void test_method( BOOST_DATA_TEST_CASE_PARAMS( params ) )               \
    {                                                                              \
        BOOST_TEST_CHECKPOINT('"' << #test_name << "\" fixture entry.");           \
        test_name t;                                                               \
        BOOST_TEST_CHECKPOINT('"' << #test_name << "\" entry.");                   \
        BOOST_TEST_CONTEXT( ""                                                     \
            BOOST_PP_SEQ_FOR_EACH(BOOST_DATA_TEST_CONTEXT, _, params))             \
        t._impl(BOOST_PP_SEQ_ENUM(params));                                        \
        BOOST_TEST_CHECKPOINT('"' << #test_name << "\" exit.");                    \
    }                                                                              \
private:                                                                           \
    template<BOOST_PP_ENUM_PARAMS(arity, typename Arg)>                            \
    void _impl(BOOST_DATA_TEST_CASE_PARAMS( params ));                             \
};                                                                                 \
                                                                                   \
BOOST_AUTO_TU_REGISTRAR( test_name )(                                              \

                                                                                   \

BOOST_DATA_TEST_CASE 的示例用法:

#include <boost/range/iterator_range.hpp>
#include <boost/filesystem/path.hpp>
#include <boost/filesystem/operations.hpp>

struct fixure
{
    fixure() :
        _Mydir(boost::filesystem::temp_directory_path() / boost::filesystem::unique_path("test-%%%%-%%%%-%%%%-%%%%"))
    {
        create_directory(_Mydir);
    }

    ~fixure()
    {
        _TRY_BEGIN
            remove_all(_Mydir);
        _CATCH_ALL
        _CATCH_END
    }

    boost::filesystem::path const _Mydir;
};

BOOST_FIXTURE_TEST_SUITE(suite, fixure)

namespace {

std::array<char const *, 4> const _Ourdata = { "A", "B", "C", "D" };

}

BOOST_AUTO_DATA_TEST_CASE(test, _Ourdata, _Str)
{
    BOOST_REQUIRE(_Str);
    BOOST_REQUIRE(is_directory(_Mydir));
    auto const _File = _Mydir / _Str;
    BOOST_TEST_MESSAGE(_File);
    std::fstream _Stream;
    _Stream.open(_File.c_str(), std::ios::out);
    _Stream << _Str;
    _Stream.close();
    BOOST_REQUIRE(is_regular_file(_File));
}

BOOST_AUTO_TEST_SUITE_END()

输出test_suite模式:

更新:测试套件已更新为 std::array<>使用

从 Boost 1.62 开始，您可以使用 BOOST_DATA_TEST_CASE_F 来实现此目的:

Declares and registers a data-driven test case, using a particular dataset and a fixture.

BOOST_DATA_TEST_CASE_F(my_fixture, test_case_name, dataset, var1, var2..., varN)
