Users can't do much after the install fails with the device showing
"error" under recovery. So our best choice is to reboot the device
since sometimes the system image is still bootable (i.e. on package
verification failure). At worst the device would stuck in a boot loop
where the users need the same professional knowledge to recover as
before.
Behaviors after installation failure (including data wipe):
If recovery text is visible:
No change.
If recovery text is not visible:
Old behavior: Wait under "error" screen. Reboot after UI timeout (120s)
if not connected to usb charger.
New behavior: Wait for 5s (shortens from the 120s timeout) under "error"
screen and reboot (w or w/o charger).
sideload-auto-reboot (only available for userdebug):
Old behavior: Reboot immediately after installation failure.
New behavior: Wait for 5s under "error" screen and reboot.
Bug: 35386985
Test: On angler user, device auto reboots 5s after a failing OTA.

The Recovery Image
Quick turn-around testing
mm -j && m ramdisk-nodeps && m recoveryimage-nodeps
# To boot into the new recovery image
# without flashing the recovery partition:
adb reboot bootloader
fastboot boot $ANDROID_PRODUCT_OUT/recovery.img
Running the tests
# After setting up environment and lunch.
mmma -j bootable/recovery
# Running the tests on device.
adb root
adb sync data
# 32-bit device
adb shell /data/nativetest/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest/recovery_component_test/recovery_component_test
# Or 64-bit device
adb shell /data/nativetest64/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest64/recovery_component_test/recovery_component_test
Running the manual tests
recovery-refresh and recovery-persist executables exist only on systems without
/cache partition. And we need to follow special steps to run tests for them.
-
Execute the test on an A/B device first. The test should fail but it will log some contents to pmsg.
-
Reboot the device immediately and run the test again. The test should save the contents of pmsg buffer into /data/misc/recovery/inject.txt. Test will pass if this file has expected contents.
ResourceTest validates whether the png files are qualified as background text
image under recovery.
1. `adb sync data` to make sure the test-dir has the images to test.
2. The test will automatically pickup and verify all `_text.png` files in
the test dir.
