Core Connection

Check that the site closed the connection as required when faced with various types of incorrect behaviour from our side.

The site object passed by Validator::Site a SiteProxy object. We can redefine methods on this object to modify behaviour after the connection has been established. To ensure that the modfid SityProxy is not reused in later tests, we use Validator::Site.isolate, rather than the more common Validator::Site.connect.

Tests

• Connection is closed if watchdogs are not acknowledged
• Connection is not closed if watchdogs are not received

Connection is closed if watchdogs are not acknowledged

1. Given the site has just connected
2. When our supervisor does not acknowledge watchdogs
3. Then the site should disconnect

View Source

timeout = Validator.get_config('timeouts','disconnect')
Validator::Site.isolated do |task,supervisor,site_proxy|
  supervisor.ignore_errors RSMP::DisconnectError do
    log "Disabling watchdog acknowledgements, site should disconnect"
    def site_proxy.acknowledge original
      if original.is_a? RSMP::Watchdog
        log "Not acknowledgning watchdog", message: original
      else
        super
      end
    end
    site_proxy.wait_for_state :disconnected, timeout: timeout
  end
rescue RSMP::TimeoutError
  raise "Site did not disconnect within #{timeout}s"
end

Connection is not closed if watchdogs are not received

1. Given the site has just connected
2. When our supervisor stops sending watchdogs
3. Then the site should not disconnect

Validator::Site.isolated do |task,supervisor,site|
  timeout = Validator.get_config('timeouts','disconnect')
  wait_task = task.async do
    site.wait_for_state :disconnected, timeout: timeout
    raise RSMP::DisconnectError
  rescue RSMP::TimeoutError
    # ok, no disconnect happened
  end
  log "Stop sending watchdogs, site should not disconnect"
  site.with_watchdog_disabled do
    wait_task.wait
  end
end
