[pypy-dev] test_all.py can't recognize has multi inherited classes

[James Lan]

Hi All,

I tried to run test cases for jvm backend by the following command,


    pypy pypy/test_all.py rpython/translator/jvm/test


but what I got was 10 tests defined in
rpython/translator/jvm/test/test_backendopt.py although there are two
dozens of test files in that directory.

After experiment, I found that it failed to collect test within a multi
inherited class. Take test_constant.py as an example, it defines a class,


    class TestConstant(BaseTestConstant, JvmTest):
        pass


and JvmTest is defined as,


    class JvmTest(BaseRtypingTest, OORtypeMixin):
        ......


When I executed the folloing,


    ypy pypy/test_all.py rpython/translator/jvm/test/test_constant.py
--collectonly


it reported 0 item was collected. If I remove BaseTestConstant from
TestConstant's super classes, it still reports 0 item collected; but if I
remove JvmTest from its super classes, it reports 18 items are collected.


I'm wondering how the daily test solve this problem?

Thanks,
James Lan
