Launch Latency

Summary

Measures elapsed time from the first launch of an application to a series of defined startup events.

Precision

This would be filled in with the estimated precision of the test. For example, we might trust the results within 10ms or we might trust them within 100ms. The latter would imply very different margins before we could assume a regression.

Scenarios

Launch each of the following apps from a cold state:

• Browser
• Camera
• Contacts
• Dialer
• Email
• Gallery
• Marketplace
• Settings
• SMS

For each app, report the time elapsed to the following events:

• moz-chrome-dom-loaded
• moz-chrome-interactive
• moz-app-visually-complete
• moz-content-interative
• moz-app-loaded

Dashboards

This should be a series of links to dashboards per branch, device, and test. Unfortunately, Datazilla doesn't seem to allow direct linking without embedding revisions, specific implemented apps, and other time-specific artifacts in the URL. This is a real problem.

startup_>_moz-chrome-interactive	link

startup_>_moz-content-interative	link

Procedure

This needs more detail.

1. Clear app from memory
2. Inject launch command
3. Monitor app events for each of the five events under Scenarios
4. Time elapsed is the time between that event and start time?
