Boost.Test 不将内存泄漏视为失败

Question

#define BOOST_TEST_MODULE test
#include <boost/test/unit_test.hpp>

BOOST_AUTO_TEST_CASE(test)
{
    int * i = new int;
    BOOST_CHECK(i==0);
}

以上测试用例明显失败。内存泄漏也被正确报告。但是，如果我将测试从 i==0 更改为 i!=0，它会毫无问题地成功并且不关心是否存在内存泄漏。

这是一个错误还是我错过了一些配置，使 Boost.Test 将内存泄漏视为故障？

如果内存泄漏，

Boost.Test 可以很容易地展开以失败测试。对于未来的读者，我包括我的解决方案：

#define MY_TEST_CASE(name)              \
    void my_test_cases__##name();       \
    BOOST_AUTO_TEST_CASE(name)          \
    {                                   \
        mytests::heap heap_scope;       \
        my_test_cases__##name();        \
        (void)heap_scope;               \
    }                                   \
    void my_test_cases__##name()

namespace mytests
{
    class heap
    {
#   if !defined(NDEBUG) && defined(_MSC_VER)
    public:
        heap()
        {
            _CrtMemCheckpoint(&oldState);
        }

        ~heap()
        {
            _CrtMemState curState, diffState;

            _CrtMemCheckpoint(&curState);

            int leaked_memory = _CrtMemDifference(&diffState,&oldState,&curState);

            BOOST_REQUIRE(leaked_memory==0);
        }

    private:
        _CrtMemState oldState;
#   endif
    };
}

那么就用MY_TEST_CASE代替BOOST_AUTO_TEST_CASE

MY_TEST_CASE(test)
{
    // various
    // tests
    // .
    // .
    // .
}

如果任何堆内存泄漏，您的单元测试将报告错误并失败。

Boost Test 是一个单元测试框架。

泄漏检测不是核心功能。

文档说：

Memory leaks detection

The Execution Monitor provides a limited ability to detect memory leaks during program execution, and to break program execution on specific memory allocation order-number (1 - first allocation of memory in program, 2 - second and so on).

Unfortunately this feature is, at the moment, implemented only for the Microsoft family of compilers (and Intel, if it employs Microsoft C Runtime Library).

Also it can not be tuned per instance of the monitor and is only triggered globally and reported after the whole program execution is done. In a future this ought to be improved.
