-------------------------------------
Summary: TestTaxonomyFacetAssociations test failure
Key: LUCENE-10530
URL: https://issues.apache.org/jira/browse/LUCENE-10530
Project: Lucene - Core
Issue Type: Bug
Reporter: Vigya Sharma
TestTaxonomyFacetAssociations.testFloatAssociationRandom seems to have some
flakiness, it fails on the following random seed.
{code:java}
./gradlew test --tests TestTaxonomyFacetAssociations.testFloatAssociationRandom
\
-Dtests.seed=4DFBA8209AC82EB2 -Dtests.slow=true -Dtests.locale=fr-VU \
-Dtests.timezone=Europe/Athens -Dtests.asserts=true -Dtests.file.encoding=UTF-8
{code}
This is because of a mismatch in (SUM) aggregated multi-valued,
{{float_random}} facet field. We accept an error delta of 1 in this
aggregation, but for the failing random seed, the delta is 1.3. Maybe we should
change this delta to 1.5?
My hunch is that it is some floating point approximation error. I'm unable to
repro it without the randomization seed.
