@williamfgc Hi William, since I'm working on make BP tests able to run parallel, I can handle this issue.

Hi @HaochengLIU thanks for reminding me I had an open ticket. This should have been fixed in PR #231, we need to add more tests for names in the form: /path/a/b/c/file. If you don't mind, please go ahead and add tests you think would be meaningful. It also has an automatic OS path separator (Windows = \, Unix-like = / ) implemented in adios2/source/ADIOSTypes.h

Thanks @williamfgc , I've incorporated the OS path separator in PR #252 - TestBPWriteReadAttributes.
