FAQ item request: Accessing current testcase name

[eyalroz]

I couldn't find this in the documentation or the FAQ: Is it possible to obtain the current test case's name from within that testcase's code? I mean, it should be, but how do we do it? That should be either in the FAQ or in some other relevant documentation file, IMHO.

That's a good idea. I'll probably look into this for the next version of doctest, and maybe I should also look at #184 - basically the ability to introspect what is registered.

For now what you can do is define a function like the following:

const char* getCurrentTestName() { return doctest::detail::g_cs->currentTest->m_name; }

in the translation unit where the framework is implemented (where DOCTEST_CONFIG_IMPLEMENT is defined) and then you can forward declare it anywhere you choose and use it.

I also think this would be a good feature to have.
My use case is when doing benchmarks with nanobench, it would be practical to use the same name for the benchmark and the test. getCurrentTestName would be great because in the case of templated test cases, it already includes the template parameters.

Besides getCurrentTestCaseName(), can we also have getCurrentSubCaseName()?
I hope we can see these API's soon, thanks!

Would love to see this feature added!
