Rspec test failure about relative url

Hello I’ve got trouble about discourse settings.

discourse version is 1.6.1 and I Have Some Question.

File : config/discourse_defaults.conf

# set to relative URL (for subdirectory hosting)
# IMPORTANT: path must not include a trailing /
# EG: /forum
relative_url_root = /

when I make it ‘/’(root), rspec test passed all cases. But When I change it ‘/url’, rspec test failed 81 cases.
I checked some test code in spec folder, some test case’s expected value is hard coded and the other is not.

This is my question.
If I fix relative_url_root on setting, Is there any other setting which I must change? or Should I fix the Test Code?

Here’s the Failure list.
