in my project,there are some files needed to be exist while the program is running.for example some xlst files,which are used in xml transforming.

i set the property of these files to "always copy",and i use these files with relative path,like "./xsltFiles/test.xslt"

but,while i am running my unit testing, my program just can't find all these files. obviously,these files didn't be copied to the out folder which is the working directory under unit testing

Is there any way to make my files be copied correctly,as compiling the project directly?

Thank you
