# This script should be used outside of the build system to run image tests.
# It needs a json file as input as exported by the build.
# E.g for an already built image:
#- export the tests:
#   TEST_EXPORT_ONLY = "1"
#   TEST_TARGET  = "simpleremote"
#   TEST_TARGET_IP = "192.168.7.2"
#   TEST_SERVER_IP = "192.168.7.1"
# bitbake core-image-sato -c testimage
# Setup your target, e.g for qemu: runqemu core-image-sato
# cd build/tmp/testimage/core-image-sato
# ./runexported.py testdata.json
