Create tests at run-time (google test)

Use value-parameterized tests:

typedef std::pair<std::string, std::string> TestParam;

class ParserTest : public testing::TestWithParam<TestParam> {};

TEST_P(ParserTest, ParsesAsExpected) {
   test_parameters = yaml_conf.get_parameters(GetParam().first,
                                              GetParam().second);
   g_parser.parse(test_parameters);
   ASSERT_TRUE(g_env.parsed_as_expected());
}

INSTANTIATE_TEST_CASE_P(
    GeneralAndSpecial,
    ParserTest,
    testing::Values(
        TestParam("General", "GeneralTestCase")
        TestParam("Special", "SpecialTestCase1")
        TestParam("Special", "SpecialTestCase2")));

You can read the list of test cases from disk and return it as a vector:

std::vector<TestParam> ReadTestCasesFromDisk() { ... }

INSTANTIATE_TEST_CASE_P(
    GeneralAndSpecial,  // Instantiation name can be chosen arbitrarily.
    ParserTest,
    testing::ValuesIn(ReadTestCasesFromDisk()));

I have added two classes DynamicTestInfo & ScriptBasedTestInfo as well as RegisterDynamicTest function into google unit test. It requires C++17 at least (haven't analyzed backporting to C++11 or C++14) - it allow to create google unit tests dynamically / at run-time slightly simpler than current google API's.

For example usage could be something like this:

https://github.com/tapika/cppscriptcore/blob/f6823b76a3bbc0ed41b4f3cf05bc89fe32697277/SolutionProjectModel/cppexec/cppexec.cpp#L156

But this requires modified google test, see this file for example:

https://github.com/tapika/cppscriptcore/blob/f6823b76a3bbc0ed41b4f3cf05bc89fe32697277/SolutionProjectModel/logTesting/gtest/gtest.h#L819

I will try to merge changes to official google test repository.

I have changed also how tests are reported to user application (using <loc> tag) but that one requires modified google test adapter for Visual studio, for more information see following youtube video for more explanation how things works.

Using newer GTA you can get file system listing in test explorer, for example like this:
