The checks with CheckUriUriStringToWindowsFilenameA are bit chaotic and could use some improvement. The code is only tested with ASCII input as I don't build with wchar_t support.
I do one test file for each compilation unit rather than a catch all test.cpp.
Code is copyright Google and donated to uriparser under the uriparser license.
// Test UriFile.c
//
// A = ASCII
