# Send restconf rpc:s when starting from backend
|
|
# Two specific usecases that have been problematic are tested here
|
|
# In comparison test_restconf_rpc.sh:
|
|
# - uses externally started restconf, here started by backend
|
|
# - generic tests, here specific
|
|
# The first usecases is: empty status message
|
|
# 1. Start a minimal restconf
|
|
# 2. Kill it externally (or it exits)
|
|
# 3. Start a server
|
|
# 4. Query status (Error message is returned)
|
|
# The second usecase is: zombie process on exit
|
|
# 1. Start server with bad address
|
|
# 2. Zombie process appears
|
|
# The third usecase is: restconf not removed
|
|
# 1. Start server
|
|
# 2. Remove server
|
|
# 3. Check status (Error: still up)
|
|
|
|
# Magic line must be first in script (see README.md)
