The purpose of oe-selftest is to run unittest modules added from meta/lib/oeqa/selftest, which are tests against bitbake tools. Right now the script it's useful for simple tests like: - "bitbake --someoption, change some metadata, bitbake X, check something" type scenarios (PR service, error output, etc) - or "bitbake-layers <...>" type scripts and yocto-bsp tools. This commit also adds some helper modules that the tests will use and a base class. Also, most of the tests will have a dependency on a meta-selftest layer which contains specially modified recipes/bbappends/include files for the purpose of the tests. The tests themselves will usually write to ".inc" files from the layer or in conf/selftest.inc (which is added as an include in local.conf at the start and removed at the end) It's a simple matter or sourcing the enviroment, adding the meta-selftest layer to bblayers.conf and running: oe-selftest to get some results. It would finish faster if at least a core-image-minimal was built before.
