Image tests

The build system has the ability to run a series of automated tests for qemu images. All the tests are actually commands run on the target image over ssh. (and the tests themselves are written in Python, using unittest as a test runner)

The class that enables this is testimage.bbclass.

To use it add "testimage" to global inherit and call your target image with -c testimage, like this:   - for example build a qemu core-image-sato: bitbake core-image-sato   - add INHERIT += "testimage" in local.conf   - then call "bitbake core-image-sato -c testimage". That will run a standard suite of tests.

You can change the tests run by appending or overrding the TEST_SUITES variable in local.conf

The test names are the module names in meta/lib/oeqa/runtime.

Each name in TEST_SUITES represents a required test for the image. (no skipping allowed)

Appending "auto" means that it will try to run all tests that are suitable for the image (each test decides that on it's own).

Note that order in TEST_SUITES is important (it's the order tests run) and it influences tests dependencies.
