[gentoo-dev] [PATCH v2] python-utils-r1.eclass: Handle deselect/ignore in epytest

[Michał Górny]

Support (potentially global-scope) EPYTEST_DESELECT and EPYTEST_IGNORE
arrays to conveniently deselect/skip tests.  This effectively replaces
local hacks such as:

    epytest ${deselect[@]/#/--deselect }

+# @VARIABLE: EPYTEST_DESELECT
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# Specifies an array of tests to be deselected via pytest's --deselect
+# parameter, when calling epytest.  The list can include file paths,
+# specific test functions or parametrized test invocations.
+#
+# Note that the listed files will still be subject to collection,
+# i.e. modules imported in global scope will need to be available.
+# If this is undesirable, EPYTEST_IGNORE can be used instead.
