# Experimental, simple script to run a robolectric test in AOSP development environment.
# Intended for faster iteration and more specific options than atest.
#
# In particular this script will:
#  - only run tests on current SDK (35)
#  - use sqlite native mode
#  - load native libandroid_runtime built from HEAD
#  - output stdout and stderr directly to terminal
#
# Usage:
# [m -j <test_module_name> libandroid_runtime]
# run-android-test.sh <test_module_name> <test_class_name>
