Templates 带有模板化测试类的CppUnitTestingFramework

首先，这里描述了一个具有类似目标的问题：

这个问题是关于我试图解决同样的问题

使用Microsoft CPPFUnitTestFramework，我们可以使用以下内容创建单元测试：

using namespace Microsoft::VisualStudio::CppUnitTestFramework;

namespace MyUnitTests {
    TEST_CLASS(NameOfMyTestClass) {
    public:
        TEST_METHOD(MyMethod1) {
            Assert::IsTrue(false);
        }
    };
}

namespace MyUnitTests {

    ONLY_USED_AT_NAMESPACE_SCOPE
    template<MyEnumClass MeasurementType, char ExpectedShift>
    class templatedScaleTestClass : public TestClass<templatedScaleTestClass<MeasurementType,ExpectedShift>>
    {
    public:
        TEST_METHOD(Test_ExpectedShift) {
            Assert::AreEqual(ExpectedShift, Calculations::getShiftAmount(MeasurementType));
        }
    };

    ONLY_USED_AT_NAMESPACE_SCOPE template class templatedScaleTestClass<MyEnumClass::FIRST,3>;
    ONLY_USED_AT_NAMESPACE_SCOPE template class templatedScaleTestClass<MyEnumClass::THIRD,1>;
}

template<typename T>
void debugMethod(TestClass<T> *tc) {
    const TestClassInfo* classInfo = tc->__GetTestClassInfo();
    std::stringstream msg;
    msg << "Tag: " << classInfo->metadata->tag << std::endl;
    msg << "helpMethodName: " << classInfo->metadata->helpMethodName << std::endl;
    msg << "helpMethodDecoratedName: " << classInfo->metadata->helpMethodDecoratedName << std::endl;
    msg << "New method address: " << &(classInfo->pNewMethod) << std::endl;
    const MemberMethodInfo* methodInfo = T::__GetTestMethodInfo_Debug();
    msg << "methodInfo - Tag: " << methodInfo->metadata->tag << std::endl;
    msg << "methodInfo - methodName: " << methodInfo->metadata->methodName << std::endl;
    msg << "methodInfo - helpMethodName: " << methodInfo->metadata->helpMethodName << std::endl;
    msg << "methodInfo - helpMethodDecoratedName: " << methodInfo->metadata->helpMethodDecoratedName << std::endl;
    msg << "methodInfo - lineNo: " << methodInfo->metadata->lineNo << std::endl;
    Logger::WriteMessage(msg.str().c_str());
}

... (namespace, test class etc)

TEST_METHOD(Debug) { debugMethod(this); }

我想测试一组类似的测试（不使用For循环将所有断言放在一个

test\u方法

），因此我查看了

test\u类

宏：

#define TEST_CLASS(className) \
ONLY_USED_AT_NAMESPACE_SCOPE class className : public ::Microsoft::VisualStudio::CppUnitTestFramework::TestClass<className>

这会编译，在我看来，它应该允许我在template类中定义

TEST\u METHOD

s的集合，然后实例化必要的枚举和常量值集合来设置它们（也许将来会对其他参数使用某种构造函数，尽管查看CppUnitTest.h会让我怀疑这是否是另一个问题……）

但是，该类从未出现在测试资源管理器中，尝试右键单击测试（在模板代码中）并单击“运行测试”将生成以下输出：

[datetime Informational] Executing test method 'MyUnitTests.templatedScaleTestClass<MeasurementType, ExpectedShift>.Test_ExpectedShift'
[datetime Informational] No tests found to run.

[datetime Information]正在执行测试方法“MyUnitTests.templatedScaleTestClass.test\u ExpectedShift”
[日期时间信息]未找到要运行的测试。

---

编辑：不确定最后一部分（“未找到要运行的测试”）的相关性-对正常测试（无用户端模板）执行相同操作生成相同的输出。单击某个特定测试会运行.cpp文件中的所有测试。也许我使用右键单击菜单时出错了。

尽管我尝试了多次尝试将其显示出来，并检查了如下函数的输出：

using namespace Microsoft::VisualStudio::CppUnitTestFramework;

namespace MyUnitTests {
    TEST_CLASS(NameOfMyTestClass) {
    public:
        TEST_METHOD(MyMethod1) {
            Assert::IsTrue(false);
        }
    };
}

namespace MyUnitTests {

    ONLY_USED_AT_NAMESPACE_SCOPE
    template<MyEnumClass MeasurementType, char ExpectedShift>
    class templatedScaleTestClass : public TestClass<templatedScaleTestClass<MeasurementType,ExpectedShift>>
    {
    public:
        TEST_METHOD(Test_ExpectedShift) {
            Assert::AreEqual(ExpectedShift, Calculations::getShiftAmount(MeasurementType));
        }
    };

    ONLY_USED_AT_NAMESPACE_SCOPE template class templatedScaleTestClass<MyEnumClass::FIRST,3>;
    ONLY_USED_AT_NAMESPACE_SCOPE template class templatedScaleTestClass<MyEnumClass::THIRD,1>;
}

template<typename T>
void debugMethod(TestClass<T> *tc) {
    const TestClassInfo* classInfo = tc->__GetTestClassInfo();
    std::stringstream msg;
    msg << "Tag: " << classInfo->metadata->tag << std::endl;
    msg << "helpMethodName: " << classInfo->metadata->helpMethodName << std::endl;
    msg << "helpMethodDecoratedName: " << classInfo->metadata->helpMethodDecoratedName << std::endl;
    msg << "New method address: " << &(classInfo->pNewMethod) << std::endl;
    const MemberMethodInfo* methodInfo = T::__GetTestMethodInfo_Debug();
    msg << "methodInfo - Tag: " << methodInfo->metadata->tag << std::endl;
    msg << "methodInfo - methodName: " << methodInfo->metadata->methodName << std::endl;
    msg << "methodInfo - helpMethodName: " << methodInfo->metadata->helpMethodName << std::endl;
    msg << "methodInfo - helpMethodDecoratedName: " << methodInfo->metadata->helpMethodDecoratedName << std::endl;
    msg << "methodInfo - lineNo: " << methodInfo->metadata->lineNo << std::endl;
    Logger::WriteMessage(msg.str().c_str());
}

... (namespace, test class etc)

TEST_METHOD(Debug) { debugMethod(this); }
