[question] Why are SUBCASEs executed only once when within a function called multiple times?

[andreaplanet]

Description

SUBCASE's are executed only once if within a function.
I missed the documentation where it is described.

Steps to reproduce

void MyTestCase(int n)
{
	SUBCASE("") { cout << "MyTestCase:" << n << endl; }
}


TEST_CASE("lots of nested subcases") {
	cout << endl << "root" << endl;
	MyTestCase(1);
	MyTestCase(2);
}

Expected output:

root
MyTestCase:1
MyTestCase:2

Got output:

root
MyTestCase:1

Hi!

This is the expected behavior. Doctest cannot (easily) know from what callstack a subcase is defined - from the point of view of the framework there is only one subcase found while executing the test case and it is uniquely identified by the file and line it is written at (using __FILE__ and __LINE__) and by its name.

What exactly is your testing scenario? Perhaps the subcases can be extracted from the separate function?

Perhaps I should improve the documentation :)
