             Summary: Improve LuceneTestCase.defaultCodecSupportsDocsWithField to check the actual DocValuesFormat in user per-field
                 Key: LUCENE-5199
                 URL: https://issues.apache.org/jira/browse/LUCENE-5199
             Project: Lucene - Core
          Issue Type: Improvement
          Components: general/test
            Reporter: Shai Erera
            Assignee: Shai Erera


On LUCENE-5178 Han reported the following test failure:

{noformat}
[junit4] FAILURE 0.27s | TestRangeAccumulator.testMissingValues <<<
   [junit4]    > Throwable #1: org.junit.ComparisonFailure: expected:<...(0)

which can be reproduced with

{noformat}
tcase=TestRangeAccumulator -Dtests.method=testMissingValues -Dtests.seed=815B6AA86D05329C -Dtests.slow=true -Dtests.postingsformat=Lucene41 -Dtests.locale=ca -Dtests.timezone=Australia/Currie -Dtests.file.encoding=UTF-8
{noformat}

It seems that the Codec that is picked is a Lucene45Codec with Lucene42DVFormat, which does not support docsWithFields for numericDV. We should improve LTC.defaultCodecSupportsDocsWithField to take a list of fields and check that the actual DVF used for each field supports it.
