Hello There ,
Are you running BVT on windows ? if so , this is expected behavior with windows .
Windows has Maximum Path Length Limitation of 260 , hence files longer that this, is not being processed/ fails when running in wondows env
Workaround is : its windows limitation, user can run the BVT on linux to work around this
Same has been confirmed in bug 25121893
I am running BVT on windows.
But Path Length is quite shorter than 260.
So bug 25121893 is not applicable to this problem.
When there is even one multi-byte character, this problem occur.
