这个问题是关于boost :: test :: unit_test的continuation to a previous question。
我写了一个单元测试并构建了单元测试。这是构建输出:
2>------ Build started: Project: UnitTests, Configuration: Debug Win32 ------
2> stdafx.cpp
2> UnitTests.cpp
2> UnitTests.vcxproj -> F:\Src\Crash\trunk\Debug\UnitTests.exe
2>
2> Running 3 test cases...
2> Test suite "Master Test Suite" passed with:
2> 3 assertions out of 3 passed
2> 3 test cases out of 3 passed

2> Detected memory leaks!
2> Dumping objects ->

2> Data: <P C > 50 E3 43 00 00 00 00 00
2> {809} normal block at 0x0043E350, 32 bytes long.
2> Data: < V| > 10 56 7C 00 00 00 CD CD CD CD CD CD CD CD CD CD

根据经验我知道描述内存泄漏的输出是使用CRT memory leak detection。
通常,要检测源代码中的分配位置,您可以将以下内容添加到入口点的开头:
_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
_CrtSetBreakAlloc( 809 );
但是,boost :: test :: unit_test定义了自己的入口点,阻止我添加这些行。我已经尝试将这些线添加到灯具中,但没有成功。我也尝试在测试代码中添加这些行,但再次没有成功。当我尝试这些修改时,我得到以下输出:
1>------ Build started: Project: UnitTests, Configuration: Debug Win32 ------
1> UnitTests.cpp
1> UnitTests.vcxproj -> F:\Src\Crash\trunk\Debug\UnitTests.exe
1>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppCommon.targets(113,5): error MSB3073: The command ""F:\Src\Crash\trunk\Debug\\UnitTests.exe" --result_code=no --report_level=short
1>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppCommon.targets(113,5): error MSB3073: :VCEnd" exited with code -2147483645.
-ve number转换为0x80000003(一个或多个参数无效)。
有人可以建议我如何检测源代码/测试这两个内存泄漏的位置吗?
对于好奇,这是我的测试:
void DShowUtilsGetFilter()
{
// SysDevNames is a typedef for std::vector<wstring*>
using namespace Crash::DirectShow;
using namespace Crash::SystemDevices;
using namespace std;
_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );
_CrtSetBreakAlloc( 809 );
HRESULT hr = S_OK;
SysDevNames AudioDevices;
wstring wsAudioDevice;
CComPtr <IBaseFilter> spAudioFilter;
try
{
TFAIL( ListDevicesInCategory( CLSID_AudioCompressorCategory, AudioDevices ) );
if( AudioDevices.size() == 0 )
throw E_FAIL;
wsAudioDevice.assign(*AudioDevices.at(0));
TFAIL( GetFilter( CLSID_AudioCompressorCategory, wsAudioDevice, &spAudioFilter ) );
if( spAudioFilter.p )
spAudioFilter.Release();
BOOST_CHECK_EQUAL (hr, S_OK);
}
catch(...)
{
BOOST_CHECK_EQUAL( 1, 0 );
}
if( AudioDevices.size() > 0)
{
for(SysDevNamesItr itr = AudioDevices.begin(); itr != AudioDevices.end(); itr ++ )
delete *itr;
AudioDevices.clear();
}
}
答案 0 :(得分:2)
看看这里:http://www.boost.org/doc/libs/1_40_0/libs/test/doc/html/execution-monitor/user-guide.html
您可以设置一个命令行参数来中断所需的分配ID。
编辑:在命令行上使用--detect_memory_leak(从此处开始:http://www.boost.org/doc/libs/1_40_0/libs/test/doc/html/utf/user-guide/runtime-config/reference.html)
