I am writing test cases right now and I created some test files which I try to read. The absolute path is:
/home/user/code/Project/source/Project/components/Project/test/file.dat
but testing with an absolute path is bad for obvious reasons. So I try to convert the absolute path into a relative one and I don't know why it doesn't work. I created a file with the relative path
findme.dat
and I found it in
/home/user/code/Project/build/source/Project/components/Project/test/findme.dat
so I created the relative path
/../../../../../../source/Project/components/Project/test/file.dat
but the file is not open and not associated with the is object,
std::ifstream is (path);, and the is.is_open() function returns fulse.
Can you help me?
What you are using is not at all a relative path. Sure you are using the relative path syntax but not the actual meaning of what it is.
/../../../../../../source/Project/components/Project/test/file.dat
This path starts with a / which means root then finds it parent which return root again since root has no parent and goes on... The simplified version of this is:
/source/Project/components/Project/test/file.dat
So it will look for folder source in root which of-course doesn't exist.
What you should do is something like this (assuming your code is in project folder):
./test/file.dat
or if it is in some other folder within Project folder you can do something like this:
../test/file.dat
../ take you to the parent of your current code directory which under this case's assumption is Project.
