// I/O TESTS
// The following tests assume the results of extraction (i.e.: contents,
// state and width of is, contents of b) only depend on input (the string
// str). In other words, they don't consider "unexpected" errors such as
// stream corruption or out of memory. The reason is simple: if e.g. the
// stream buffer throws, the stream layer may eat the exception and
// transform it into a badbit. But we can't trust the stream state here,
// because one of the things that we want to test is exactly whether it
// is set correctly. Similarly for insertion.
//
// To provide for these cases would require that the test functions know
// in advance whether the stream buffer and/or allocations will fail, and
// when; that is, we should write both a special allocator and a special
// stream buffer capable of throwing "on demand" and pass them here.
// operator<<(ostream,
// operator>>(istream,
// Seems overkill for these kinds of unit tests.

//****************************************************************************//
// WARNING:
// ~~~~~~~
// This is a preliminary version, for internal testing only.
// For now, it stresses the count() function only and has been executed
// on a very few platforms. The previous version, for instance, was never
// executed on MSVC (boost::bitset<> didn't even compile with it) and at
// the first try it crashed at startup, presumably because of a linker bug.
// To cope with it, the definition of
//
// template <typename T> void timing_test()
//
// has been moved before the definition of main()
