-----------------------------------
Summary: remove epsilon-based testing from lucene/spatial
Key: LUCENE-7127
URL: https://issues.apache.org/jira/browse/LUCENE-7127
Project: Lucene - Core
Issue Type: Test
Reporter: Robert Muir
Currently, the random tests here allow a TOLERANCE and will fail if the error
exceeds. But this is not fun to debug! It also keeps the door wide open for
bugs to creep in.
Alternatively, we can rework the tests like we did for sandbox/ points. This
means the test is aware of the index-time quantization and so it can demand
exact answers.
Its more difficult at first, because even floating point error can cause a
failure. It requires us to maybe work through corner cases/rework
optimizations. If any epsilons must be added, they can be added to the
optimizations themselves (e.g. bounding box) instead of the user's result.
