Feature: show network stats with `trema show_stats' command
As a Trema user
I want to get packet stats with `trema show_stats' command
So that I can easily debug trema applications
Background:
Given I try trema run "learning_switch" example with following configuration (backgrounded):
"""
vswitch { datapath_id "0xabc" }
vhost("host1") { ip "192.168.0.1" }
vhost("host2") { ip "192.168.0.2" }
link "0xabc", "host1"
link "0xabc", "host2"
"""
Scenario: show_stats
When I send 1 packet from host1 to host2
Then the stats of "host1" should be:
"""
Sent packets:
ip_dst,tp_dst,ip_src,tp_src,n_pkts,n_octets
192.168.0.2,1,192.168.0.1,1,1,50
Received packets:
"""
Scenario: show_stats --tx
When I send 1 packet from host1 to host2
Then the tx stats of "host1" should be:
"""
ip_dst,tp_dst,ip_src,tp_src,n_pkts,n_octets
192.168.0.2,1,192.168.0.1,1,1,50
"""
Scenario: show_stats --rx
When I send 1 packet from host1 to host2
Then the rx stats of "host2" should be:
"""
ip_dst,tp_dst,ip_src,tp_src,n_pkts,n_octets
192.168.0.2,1,192.168.0.1,1,1,50
"""
Scenario: show_stats error
Then "./trema show_stats NO_SUCH_HOST" exits abnormally with an error message:
"""
Unknown host: NO_SUCH_HOST
"""
Scenario: trema help show_stats
When I try to run "./trema help show_stats"
Then the output should be:
"""
Usage: ./trema show_stats HOSTNAME [OPTIONS ...]
-t, --tx
-r, --rx
-h, --help
-v, --verbose
