[boost] [Test or Build?] How to add dummy files and dirs to a test?

Dear all, I'm putting the finishing touches to a Posix-conformant boost::glob function that I'd like to submit to Boost (assuming there's some interest). However, before I do so, I'd like to get the regression tests running smoothly. Currently my 'test' directory contains: $ ls .oo* foo* foo1bar foo bar foo!bar foo]bar foo*bar foocbar foo.hpp fooabar foo-bar foo?bar foo{bar foo\bar foo.cpp .oobar foo^bar foo,bar foo[bar foo}bar foobbar foo.cxx All 20 of these files have zero size; the idea is to test boost::glob's ability to find matches. However, I'd rather not have them as part of the library. How do I get the test framework to create them for me before running a test? Regards, Angus
