# testexport.bbclass allows to execute runtime test outside OE environment.
# Most of the tests are commands run on target image over ssh.
# To use it add testexport to global inherit and call your target image with -c testexport
# You can try it out like this:
# - First build an image. i.e. core-image-sato
# - Add INHERIT += "testexport" in local.conf
# - Then bitbake core-image-sato -c testexport. That will generate the directory structure
#   to execute the runtime tests using runexported.py.
#
# For more information on TEST_SUITES check testimage class.
