GTest - run multiple testcase on different parameters - c++

Question

Note: I know this question was asked in different ways, but I couldn't solve it based on my restrictions:
I am using google test version 1.7
Compiling in Visual studio 2010, with platform toolset V100
I am writing google test for a library I have created.
In my library, I have 3 structs, as follows:
struct utc_clock{ .... }
struct system_clock {....}
struct cpu_clock {....}
moreover, I have another class that uses them as template parameters.
In my test case, I do as follows:
TEST(MyTest, testImportantThings)
{
time_point<utc_clock> tp = utc_clock::now();
ASSERT_EQ(..things with tp... );
... more ASSERTION
}
What I am trying to do, is to run
TEST(MyTest, testImportantThings)
multiple times for each of the utc_clock, system_clock, cpu_clock
I have looked into How to get gtest TYPED_TEST parameter type,
after that, I got the following:
template<typename T>
struct MyTest: public testing::Test{
using MyParamType = T;
};
using MyTypes = testing::TYpes<utc_clock, system_clock, cpu_clock>;
TYPED_TEST_CASE(MyTest, MyTypes);
TYPED_TEST(MyTest, testImportantStuff)
{
using clock = typename TestFixture::MyParamType;
timepoint<clock> tp = clock::now();
ASSERT_EQ(..things with tp... );
... more ASSERTION
}
But I get the following errors:
unexpected token(s) preceding ';' on: using MyParamType = T;
testing::internal::TYpeList use of class template requires template
arguement list online on: using MyTypes = testing::TYpes<utc_clock, system_clock, cpu_clock>;
and more...

Answer 1

It is possible that your compiler is too old to support defining type aliases with using. What if you replace those with old-style typedef statements?
For example, you could replace
using MyParamType = T;
With the equivalent:
typedef T MyParamType;
