# Wrapper script to push build artifacts and run tests on an Android device.
#
# This script expects the following arguments:
#   <test-binary> [<test-args>]..
# Where <test-binary> should be a path relative to /data/local/tmp/ on device.
#
# This script reads the following environment variables:
# - TEST_ANDROID_ABS_DIR: the absolute path on Android device for the build
#   artifacts.
# - TEST_DATA: optional; the data file to push to the Android device.
# - TEST_EXECUTABLE: the executable file to push to the Android device.
# - TEST_TMPDIR: optional; temporary directory on the Android device for
#   running tests.
#
# This script pushes $TEST_EXECUTABLE and $TEST_DATA onto the device
# under $TEST_ANDROID_ABS_DIR/ before running <test-binary> with all
# <test-args> under /data/local/tmp.

# Execute the command with `adb shell` under `/data/local/tmp`.
# We set LD_LIBRARY_PATH for the command so that it can use libvulkan.so under
# /data/local/tmp when running Vulkan tests. This is to workaround an Android
# issue where linking to libvulkan.so is broken under /data/local/tmp.
# See https://android.googlesource.com/platform/system/linkerconfig/+/296da5b1eb88a3527ee76352c2d987f82f3252eb.
# This requires copying the vendor vulkan implementation under
# /vendor/lib[64]/hw/vulkan.*.so to /data/local/tmp/libvulkan.so.
