gtest-参数化测试限制,编译错误

当实例化超过50个参数化测试时,出现以下错误:

main.cpp:31: error: expected class name
main.cpp:49: error: no matching function for call to 'Values'
gtest-param-test.h:1411: expanded from macro 'INSTANTIATE_TEST_CASE_P'
gtest-param-test.h:342: candidate function template not viable: requires single argument 'v1', but 51 arguments were provided
gtest-param-test.h:347: candidate function template not viable: requires 2 arguments, but 51 were provided
gtest-param-test.h:352: candidate function template not viable: requires 3 arguments, but 51 were provided
gtest-param-test.h:357: candidate function template not viable: requires 4 arguments, but 51 were provided
//and so on

这是我使用的示例简化代码:

template <typename param>
class MyFixtureWithParam: public ::testing::Test, public ::testing::WithParamInterface<param>
{
};

using MyPair = std::pair<std::string, std::string>;
using MyTests = MyFixtureWithParam<MyPair>;

TEST_P(MyTests, Params)
{
}

INSTANTIATE_TEST_CASE_P(Params, MyTests, ::testing::Values(std::make_pair("aaa", "bbb"),
                                                           std::make_pair("aaa", "bbb")));

超过50 make_pair会产生该错误。如何解决?
