I don't think we have automated statistics, but I can assure you that
the coverage it's exactly the same. We are testing two correlated
functions with the same input, in a single test case, instead of having
a single case for each one, so that's why the number of cases is reduced.

For example, instead of:

total_tests++;
if (guid_parse(data->uuid, &le))


total_tests++;
if (!guid_equal(&data->le, &le))

We now have:

KUNIT_ASSERT_EQ(guid_parse(data->guid, &le), 0)
KUNIT_EXPECT_TRUE(guid_equal(&data->le, &le))

That will count as a single test.
