#####
# Local unit test Makefile
#
# This makefile builds and runs the keymaster unit tests locally on the development
# machine, not on an Android device.  Android.mk builds the same tests into the
# "keymaster_tests" binary for execution on-device, but this Makefile runs them locally,
# for a very fast edit/build/test development cycle.
#
# To build and run these tests, one pre-requisite must be manually installed: BoringSSL.
# This Makefile expects to find BoringSSL in a directory adjacent to $ANDROID_BUILD_TOP.
# To get and build it, first install the Ninja build tool (e.g. apt-get install
# ninja-build), then do:
#
# cd $ANDROID_BUILD_TOP/..
# git clone https://boringssl.googlesource.com/boringssl
# cd boringssl
# mdkir build
# cd build
# cmake -GNinja ..
# ninja
#
# Then return to $ANDROID_BUILD_TOP/system/keymaster and run "make".
