The existing test infrastructure relies on the full Magisk setup before it can test any functionality. However for most of the time, we just want to test the core Magisk functionality without the need of involving MagiskInit.

# AVD Magisk Setup
|
|
#####################################################################
|
|
#
|
|
# Support API level: 23 - 36
|
|
#
|
|
# For developing Magisk, just use:
|
|
# ./build.py emulator
|
|
#
|
|
# This script will stop zygote, simulate the Magisk start up process
|
|
# that would've happened before zygote was started, and finally
|
|
# restart zygote. This is useful for setting up the emulator for
|
|
# developing Magisk, testing modules, and developing root apps using
|
|
# the official Android emulator (AVD) instead of a real device.
|
|
#
|
|
# This only covers the "core" features of Magisk. For testing
|
|
# magiskinit, please checkout avd_patch.sh.
