Talos Ts

Automated Testing

Limitations

• no plans to allow addons to 'call home' - we will still be working in the talos testing environment where we are proxied to localhost, so there will be no live web interaction
• no current plans to interact with the addon (no clicks, no visiting specific pages)
  • this sort of perf test would have to be designed/built per-addon to get the most bang for the buck

Plans

• integrate into buildbot and have run on production machines
  • how frequently?
  • which tests?
    • for now, we'll limit to clean ts starts with just the addon installed
  • where would the list of addons be maintained?
  • where do we download the addons from?
• results reported as .csv files
  • where should these be sent?
  • do we want the data on the graph server?
  • how do we compare the results?
