"Dumper" sample application

In order to learn how to dump miscellaneous OpenFlow messages
As a developer using Trema
I want to execute "Dumper" sample application

Background
Given
a file named "dumper.conf" with:
vswitch("dumper") { datapath_id 0xabc }

vhost("host1")
vhost("host2")

link "dumper", "host1"
link "dumper", "host2"
Scenarios
  • @slow_process
Run "Dumper" C example
Given
I run trema run ../../objects/examples/dumper/dumper -c dumper.conf -d
And
wait until "dumper" is up
When
I send 1 packet from host1 to host2
Then
the file "../../tmp/log/dumper.log" should contain "[switch_ready]"
And
the file "../../tmp/log/dumper.log" should contain "[packet_in]"
And
the file "../../tmp/log/dumper.log" should contain "datapath_id: 0xabc"
  • @slow_process
Run "Dumper" Ruby example
Given
I run trema run ../../src/examples/dumper/dumper.rb -c dumper.conf -d
And
wait until "Dumper" is up
When
I send 1 packet from host1 to host2
Then
the file "../../tmp/log/Dumper.log" should contain "[switch_ready]"
And
the file "../../tmp/log/Dumper.log" should contain "[packet_in]"
And
the file "../../tmp/log/Dumper.log" should contain "datapath_id: 0xabc"
"dumper --help"
When
I run ../../objects/examples/dumper/dumper --help
Then
the output should contain exactly:
OpenFlow Event Dumper.
Usage: dumper [OPTION]...

  -n, --name=SERVICE_NAME         service name
  -d, --daemonize                 run in the background
  -l, --logging_level=LEVEL       set logging level
  -g, --syslog                    output log messages to syslog
  -f, --logging_facility=FACILITY set syslog facility
  -h, --help                      display this help and exit
"dumper -h"
When
I run ../../objects/examples/dumper/dumper -h
Then
the output should contain exactly:
OpenFlow Event Dumper.
Usage: dumper [OPTION]...

  -n, --name=SERVICE_NAME         service name
  -d, --daemonize                 run in the background
  -l, --logging_level=LEVEL       set logging level
  -g, --syslog                    output log messages to syslog
  -f, --logging_facility=FACILITY set syslog facility
  -h, --help                      display this help and exit
