Robert Muir commented on LUCENE-3357:
-------------------------------------
Ok I added some things (marked nocommit for your review):
Basically we have the case for norms/totalTermFreq/sumTotalTermFreq that they
can be unavailable because
freqs or norms are omitted, but currently all sims have to deal with this
problem :(
Ideally sims would not have to deal with this stuff, but for the time being it
prevents NaN/Inf for the hearts test
if the test gets preflexcodec (about 1/4 of the time), and it will prevent NPE
if norms are omitted.
in the case these values are unavailable i set these to "1"... if you can
review that this is ok, we can nuke the nocommits.

> Write test cases to test the new Similarities added in
> [LUCENE-3220|https://issues.apache.org/jira/browse/LUCENE-3220]. Two types of
> test cases will be created:
> * unit tests, in which mock statistics are provided to the Similarities and
> the score is validated against hand calculations;
> * integration tests, in which a small collection is indexed and then
> searched using the Similarities.
> Performance tests will be performed in a separate issue.
