How are tests designed in Clang? More specifically:
- How should a test file be named?
For tests in CXX/, it seems to be named after a paragraph in the standard, with "-0x" for C++0x feature testing, and placed in a directory named after the section in the standard. If so, what document are we using for the C++0x standard? I thought it might be N3242, but there is a test named clang/test/CXX/expr/expr.prim/p12-0x.cpp, and I don't see a paragraph 12 in section 5.1 [expr.prim].
- What should go in the test?
For C++, I'm guessing we test parsing diagnostics in CXX/ and sema diagnostics in SemaCXX/?
Most tests in CXX/ are run with "-fsyntax-only -verify", but some aren't. How do I determine the best way to run the test?

Use the FDIS as your guide. Many tests predate the FDIS, and paragraphs have moved around, so the test paragraph numbers are out of date.

Parsing tests can also go into test/Parse.
test/CXX is meant for general testing. Some parsing, mostly semantic analysis.
Most tests in CXX/ are run with "-fsyntax-only -verify", but some
aren't. How do I determine the best way to run the test?
If it doesn't require code generation, use -fsyntax-only -verify.
