Varun Thacker created SOLR-5873:
-----------------------------------
Summary: Improve JavaBinCodec's backward compatibility tests
Key: SOLR-5873
URL: https://issues.apache.org/jira/browse/SOLR-5873
Project: Solr
Issue Type: Improvement
Reporter: Varun Thacker
SOLR-5265 added backward compatibility tests, but it tries to read a
pre-written binary file to check if there is a break a not. If we add more
types to JavaBinCodec the test will need to be updated too, which will be error
prone again.
This is what [~hakeber] proposed on IRC -
- A test that I was thinking of: we could have a jenkins job that ran a script
that checked out the previous version of lucene and the the latest
- Then use the solr/cloud-dev scripts to start a cloud cluster
- Index some docs
- Stop a node at a time, replace webapp with the latest in a rolling upgrade
fashion
- Then we have a full rolling upgrade test
This would be a better approach for back compat tests.
