madrob opened a new pull request #1412: Add MinimalSolrTest for scale testing
URL: https://github.com/apache/lucene-solr/pull/1412
 
 
   
   This test class does a few very basic things, but it does them at several 
scales. Improvements to this test will impact nearly everything else in the 
test suite. Everything that happens here already has test coverage via other 
tests, but this class is still useful for several scenarios:
   
   
    * Isolating the startup and teardown costs for a cluster
    * Capturing the startup time in a unit test rather than `@Before` methods
    * Profiling basic setup operations like cluster start or collection creation
    * Easily adjusting the scale of the tests - we rarely touch 100+ nodes in 
our test suite otherwise
   
   In an effort to minimize overhead and other operations, we disable most 
logging. When troubleshooting specific areas you will likely find it useful to 
tweak these settings.
   
   The commented run times for each method are rough measures from a single 
desktop computer. They will vary between environments, but the intent is to 
have some baseline for spotting regressions.
