----------------------------------------
Summary: Support disabling Locale randomization as part of Lucene
test framework
Key: LUCENE-8009
URL: https://issues.apache.org/jira/browse/LUCENE-8009
Project: Lucene - Core
Issue Type: Improvement
Components: modules/test-framework
Affects Versions: 7.1
Reporter: Hrishikesh Gadre
Priority: Minor
The Lucene test framework randomizes the Locale configuration to test the
software in different locale settings.
https://github.com/apache/lucene-solr/blob/e2521b2a8baabdaf43b92192588f51e042d21e97/lucene/test-framework/src/java/org/apache/lucene/util/TestRuleSetupAndRestoreClassEnv.java#L206-L209
While this is a very good practice from engineering perspective, it causes
issues when the Lucene/Solr test framework is used with third-party components
which may have issues working with a subset of locale settings. e.g. for
Solr/Sentry integration (SENTRY-1475), we are using Solr test framework to test
the sentry authorization plugin for Solr. For unit-testing, it uses Apache
Derby. We have found multiple cases when derby fail to initialize for a locale
configured by Solr test framework. This causes tests to fail and create a
confusion with respect to the quality of the integration source-code. Since the
Derby failures are not related to Solr/Sentry integration, we would like to
avoid such nasty surprises by suppressing the locale randomization. This is
similar to the way we suppress Solr SSL configuration
(@SolrTestCaseJ4.SuppressSSL).
