Googletest参数化测试崩溃 [英] Googletest Parametrized tests crash
问题描述
我刚刚了解了 googletest中的值参数化单元测试
标题：
#include< gtest / gtest.h>
namespace EnsembleClustering {
class ParametrizedGTest：public testing :: TestWithParam< int> {
public：
ParametrizedGTest（）;
virtual〜ParametrizedGTest（）;
};
} / * namespace EnsembleClustering * /
#includeParametrizedGTest.h
namespace EnsembleClustering {
ParametrizedGTest :: ParametrizedGTest （）{
// TODO自动生成的构造函数stub
}
ParametrizedGTest ::〜ParametrizedGTest（）{
// TODO自动生成destructor stub
}
TEST_P（ParametriizedGTest，testParameter）{
int n = GetParam（）;
EXPECT_EQ（n，getParam（））;
}
INSTANTIATE_TEST_CASE_P（ParametrizedGTestInstance，
ParametrizedGTest，
:: testing :: Values（100））;
} / * namespace EnsembleClustering * /
像往常一样，程序崩溃，没有任何输出。 gdb堆栈跟踪是

我做错了什么或者这是googletest中的错误？您可以重现此错误吗？
编辑：我在Mac OS X 10.8。
从查看gtest的源代码的唯一情况下，如果没有参数化测试可用是在Windows上使用VC7.1与禁用的异常：
//我们不支持MSVC 7.1，现在禁用例外。因此
//我们关心的所有编译器都足以支持
//值参数化测试。
#define GTEST_HAS_PARAM_TEST 1
因此，您需要检查您的MinGW的构建并可能更新它？
有关MinGW的更多信息：
在他们的常见问题他们报告，当使用MinGW时，需要以下编译选项来构建gtest： PATH / TO / configure CC =gcc -mno-cygwinCXX = g ++ -mno-cygwin。
完成示例：
<
#include< gtest / gtest.h>
namespace EnsembleClustering {
class ParametrizedGTest：public testing :: TestWithParam< int> {
public：
ParametrizedGTest（）;
virtual〜ParametrizedGTest（）;
};
ParametrizedGTest :: ParametrizedGTest（）{
}
ParametrizedGTest ::〜ParametrizedGTest（）{
}
TEST_P （ParametrizedGTest，testParameter）{
int n = GetParam（）;
EXPECT_EQ（n，GetParam（））;
}
INSTANTIATE_TEST_CASE_P（ParametrizedGTestInstance，
ParametrizedGTest，
:: testing :: Values（100））;
} / * namespace EnsembleClustering * /
int main（int argc，char * argv []）{
:: testing :: InitGoogleTest （& argc，argv）;
return RUN_ALL_TESTS（）;
}
我在Mac OS X 10.8上使用以下编译器调用编译此代码： / p>
g ++ -IGTEST_INCLUDE_DIR -LGTEST_LIB_DIR -lgtest -o tt2 tt2.cpp
其中 GTEST_INCLUDE_DIR 和 GTEST_LIB_DIR 并存储库文件。当你编译和执行时，会发生什么？
I've just learned about value-parametrized unit tests in googletest and would like to use them in my project.
I wrote a simple parametrized test.
Header:
#include <gtest/gtest.h>
namespace EnsembleClustering {
class ParametrizedGTest: public testing::TestWithParam<int> {
public:
ParametrizedGTest();
virtual ~ParametrizedGTest();
};
} /* namespace EnsembleClustering */
Source:
#include "ParametrizedGTest.h"
namespace EnsembleClustering {
ParametrizedGTest::ParametrizedGTest() {
// TODO Auto-generated constructor stub
}
ParametrizedGTest::~ParametrizedGTest() {
// TODO Auto-generated destructor stub
}
TEST_P(ParametrizedGTest, testParameter) {
int n = GetParam();
EXPECT_EQ(n, GetParam());
}
INSTANTIATE_TEST_CASE_P(ParametrizedGTestInstance,
ParametrizedGTest,
::testing::Values(100));
} /* namespace EnsembleClustering */
Now, when I run googletest as usual, the program crashes without any output. The gdb stack trace is

Am I doing something wrong or is this a bug in googletest? Can you reproduce this error?
EDIT: I am on Mac OS X 10.8.
From looking at the source code of gtest the only case if there are no parametrized tests available is on Windows using VC7.1 with disabled exceptions:
// We don't support MSVC 7.1 with exceptions disabled now. Therefore
// all the compilers we care about are adequate for supporting
// value-parameterized tests.
#define GTEST_HAS_PARAM_TEST 1
So, you'll need to check how your MinGW was built and probably update it? And can you run the gtest unit tests to see if they execute the typed parameters test?
More information on MinGW:
On their FAQ they report that when using MinGW the following compile option for building gtest is required: PATH/TO/configure CC="gcc -mno-cygwin" CXX="g++ -mno-cygwin".
Complete Example:
#include <gtest/gtest.h>
namespace EnsembleClustering {
class ParametrizedGTest: public testing::TestWithParam<int> {
public:
ParametrizedGTest();
virtual ~ParametrizedGTest();
};
ParametrizedGTest::ParametrizedGTest() {
}
ParametrizedGTest::~ParametrizedGTest() {
}
TEST_P(ParametrizedGTest, testParameter) {
int n = GetParam();
EXPECT_EQ(n, GetParam());
}
INSTANTIATE_TEST_CASE_P(ParametrizedGTestInstance,
ParametrizedGTest,
::testing::Values(100));
} /* namespace EnsembleClustering */
int main(int argc, char* argv[]) {
::testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}
I compiled this code using the following compiler call on Mac OS X 10.8:
g++ -IGTEST_INCLUDE_DIR -LGTEST_LIB_DIR -lgtest -o tt2 tt2.cpp
Where GTEST_INCLUDE_DIR and GTEST_LIB_DIR are the path where header and library files are stored. When you compile and execute, what happens?
