[jira] [Comment Edited] (BEAM-5617) Several tests fail on Python 3 with failed assert: == []

["Valentyn Tymofieiev (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/BEAM-5617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16642684#comment-16642684 ]

--------------------------------------------------------------------

It appears that lines 1272-1274 are not executed for apache_beam.transforms.sideinputs_test.SideInputsTest.test_iterable_side_input, so failure may be somewhere else (for that particular test at least). One possible way to track this down would be to go over functions/methods that are invoked during test execution, and see when do the arguments passed to the functions/methods start to diverge between Python 2 and Python 3. I didn't get to the bottom of the issue yet, but will continue looking tomorrow, if we don't rootcause it by then.
