FeatureFlagTargetPreparer
public
class
FeatureFlagTargetPreparer
extends BaseTargetPreparer
Updates the DeviceConfig (feature flags tuned by a remote service).
This can be used to reproduce the state of a device (by dumping all flag values to a file
using `adb shell device_config list`) or to bulk enable/disable flags (all-on/all-off testing).
Example usage:
- To use for all-on/all-off testing, specify the necessary flag file:
--flag-file=flag_file_path
- To override one or more flags, specify their values (can be combined with flag files):
--flag-file=flag_file_path --flag-value=namespace/name=value
- To use for reversibility testing, specify the all-on file followed by the all-off file, and
enable rebooting between the two files:
--flag-file=all_on_file_path --flag-file=all_off_file_path --reboot-between-flag-files
Should be used in combination with DeviceSetup
to disable DeviceConfig syncing during
the test which could overwrite the changes made by this preparer.
