|
|
|
|
Performs an end-to-end test of updating a ChromeOS device from one version
|
|
to another. The test performs the following steps:
|
|
|
|
- Stages the source (full) and target update payloads on a devserver.
|
|
- Installs source image on the DUT (if provided) and reboots to it.
|
|
- Verifies that sign in works correctly on the source image.
|
|
- Installs target image on the DUT and reboots.
|
|
- Does a final update check.
|
|
- Verifies that sign in works correctly on the target image.
|
|
- Returns the hostlogs collected during each update check for
|
|
verification against expected update events.
|
|
|
|
This class interacts with several others:
|
|
UpdateEngineTest: base class for comparing expected update events against
|
|
the events listed in the hostlog.
|
|
UpdateEngineEvent: class representing a single expected update engine event.
