# Bootstat boot reason tests
#
# throughout testing:
# - manual tests can only run on eng/userdebug builds
# - watch adb logcat -b all -d -s bootstat
# - watch adb logcat -b all -d | audit2allow
# - wait until screen is up, boot has completed, can mean wait for
#   sys.boot_completed=1 and sys.bootstat.first_boot_completed=1 to be true
#
# All test frames, and nothing else, must be function names prefixed and
# specifiged with the pattern 'test_<test>() {' as this is also how the
# script discovers the full list of tests by inspecting its own code.
