It is often useful to run a suite of tests multiple times, varying one or more parameters.

GTest supports this through value-parameterized tests.

For example:

 class FixtureClass : TestWithParam<int> {
 };
 
TEST_P(FixtureClass, TestThatUsesParameterizedFixture) {
    int param = GetParam();
    // ... do a test using the given parameter
}

TEST_P(FixtureClass, AnotherTestThatUsesParameterizedFixture) {...}

INSTANTIATE_TEST_SUITE_P(SomeUniquePrefix, FixtureClass, Values(1, 2, 3, 4))

Such functionality would be a useful addition to the unittest framework, as it does not appear to currently be supported.

To explore the viability of adding this to the framework, I've created a proof of concept: github.
