# Restconf basic functionality also uri encoding using eth/0/0
|
||||
# Note there are many variants: (1)fcgi/native, (2) http/https, (3) IPv4/IPv6, (4)local or backend-config
|
||||
# (1) fcgi/native
|
||||
# This is compile-time --with-restconf=fcgi or native, so either or
|
||||
# - fcgi: Assume http server setup, such as nginx described in apps/restconf/README.md
|
||||
# - native: test both local config and get config from backend
|
||||
# (2) http/https
|
||||
# - fcgi: relies on nginx has https setup
|
||||
# - native: generate self-signed server certs
|
||||
# (3) IPv4/IPv6 (only loopback 127.0.0.1 / ::1)
|
||||
# - The tests runs through both
|
||||
# - IPv6 by default disabled since docker does not support it out-of-the box
|
||||
# (4) local/backend config. Native only
|
||||
# - The tests runs through both (if compiled with native)
