Debugging TO in a local (dev) environment
Hi,
I'm running a local instance of TO, and debugging the CDN health API route
/api/1.2/cdns/health
In order to report the CDN health, TO need to read cache status from
Traffic Monitor, which in turn, has to collect status from the caches.
I am looking for a way to create a dev setup on which I can debug such use
cases, without having to run numerous monitors and caches.
Does the unit/integration test framework provides infrastructure to mock
Traffic Monitor responses?
Are there other kind of mocks that can mimic Traffic Monitor responses?
I'd appreciate any tips and practices.
Thanks

You should be able to just run it like this:
/usr/local/bin/node
/git/apache/incubator-trafficcontrol/traffic_monitor/etc/ats_sim.js
https://<traffic_ops_url>/CRConfig-Snapshots/<cdn_name>/CRConfig.json
<port>

Hi Dave,
Can you elaborate on how to run the ats_sim.js script?
I tried to run it as a stand alone script, using the node command line, but
the requests against TO are unauthorized, as it does not handle login.
Thanks

+1, we have some internal tools floating around to do some of that, but
nothing available publicly (or ready for public consumption). I would
definitely be in favor of adding some of those things to the project.

Thanks a lot, Dave,
I'd like to consider investing in such testing tools.
In addition to cache simulation, we can create clients simulation, to debug
request routing path. A Traffic Monitor mock, to debug motioning path
without caches,
and maybe more.
I would be glad to hear any insights about this.
Thanks

Hey Amiry,
Unfortunately we do not have a mock version of Traffic Monitor to use for
testing. We do, however, have an ATS simulator here:
https://github.com/apache/incubator-trafficcontrol/blob/master/traffic_monitor/etc/ats_sim.js
which you can use with a Traffic Monitor to simulate traffic monitor
polling caches and sending responses.
Hopefully that helps.
Thanks,
Dave
