Subject: testsdk.bbclass: check python module testtools and subunit
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fheads%2Frbt%2Ftesttools;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

testsdk.bbclass: check python module testtools and subunit

The testtools or subunit is not part of python's standard library, so check them
before use.

Fixed when they are not installed on host:
$ bitbake core-image-minimal -ctestsdk
Exception: ImportError: No module named 'testtools'

Now it can run with a warning:
WARNING: core-image-minimal-1.0-r0 do_testsdk: Failed to import testtools or subunit, the testcases will run serially
