[jira] [Commented] (QUARKS-143) bogus test behavior with
DevelopmentProvider
[ https://issues.apache.org/jira/browse/QUARKS-143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15244482#comment-15244482 ]
Cazen Lee commented on QUARKS-143:
----------------------------------
Good day [~dlaboss]
How about
{code}
s = s.filter(tuple ->
{ System.out.println("filter tuple: "+tuple); return true; }
);
{/code}
instead of
{code}
s.filter(tuple ->
{ System.out.println("filter tuple: "+tuple); return true; }
);
{/code}

> Key: QUARKS-143
> URL: https://issues.apache.org/jira/browse/QUARKS-143
> Project: Quarks
> Issue Type: Bug
> Components: Runtime
> Reporter: Dale LaBossiere
>
> I'm perplexed... if you add the following test to TStreamTest and run the DirectTStreamTest it works. If you run the DevelopmentTStreamTest it fails as noted in the commentary.
>
> @Test
> public void testBrokenDevelopmentProvider() throws Exception {
> Topology t = newTopology();
>
> // For some reason, the following sequence fails with no content
> // received by the tester when run with the DevelopmentProvider.
> //
> // Commenting out either the s.filter() OR the s.peek() makes it work.
> // OR putting the peek() before the filter() statement works!???
> //
> // This runs fine with the DirectProvider.
> //
> // I understand that given the structure of this test, the test
> // could reach completion before either the filter or peek was actually
> // called for the second tuple but that doesn't mean the tester
> // should receive/report no tuples. (in practice, the full println
> // output is present when it fails).
> TStream<String> s = t.strings("a", "b");
> s.filter(tuple -> { System.out.println("filter tuple: "+tuple); return true; });
> s.peek(tuple -> System.out.println("peek tuple: "+tuple));
> Condition<Long> tc = t.getTester().tupleCount(s, 2);
> Condition<List<String>> contents = t.getTester().streamContents(s, "a", "b");
> complete(t, tc);
> assertTrue("contents "+contents.getResult(), contents.valid());
> }
