Subject: oe-selftest: fix handling of test cases without ID in --list-tests-by
X-Git-Tag: uninative-1.5~1401
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=71c6790689e2cbd3c4e882335b3b03e635ad46ed;p=openembedded-core.git

oe-selftest: fix handling of test cases without ID in --list-tests-by

Running `oe-selftest --list-tests-by module wic` will produce the
following backtrace:

Traceback (most recent call last):
  File "<snip>/poky/scripts/oe-selftest", line 668, in <module>
    ret = main()
  File "<snip>/poky/scripts/oe-selftest", line 486, in main
    list_testsuite_by(criteria, keyword)
  File "<snip>/poky/scripts/oe-selftest", line 340, in list_testsuite_by
    ts = sorted([ (tc.tcid, tc.tctag, tc.tcname, tc.tcclass, tc.tcmodule) for tc in get_testsuite_by(criteria, keyword) ])
TypeError: unorderable types: int() < NoneType()

The root cause is that a test case does not necessarily have an ID
assigned, hence its value is None. Since Python 3 does not allow
comparison of heterogeneous types, TypeError is raised.
