# This module adds support to testimage.bbclass to deploy images and run

# tests using a "master image" - this is a "known good" image that is
|
|
# installed onto the device as part of initial setup and will be booted into
|
|
# with no interaction; we can then use it to deploy the image to be tested
|
|
# to a second partition before running the tests.
|

|

# For an example master image, see core-image-testmaster
