Please note that I am not writing unit tests for testing classes in Solr. I need a temporary Solr index to test classes in my own application that needs a Solr index. I would like to use classes that are available in solr-core and solr-solrj jars. I could do this easily in solr-4.x versions using EmbeddedSolrServer. I prefer not to extend SolrTestCaseJ4 class. Also MiniSolrCloudCluster is not available in solr-core or solr-solrj jar.
What is the best way of doing this in Solr-6.x / Solr-7.0 ? -----Original Message----- From: Joe Lawson [mailto:jlaw...@opensourceconnections.com] Sent: 11 April 2016 17:31 To: solr-user@lucene.apache.org Subject: Re: EmbeddedSolr for unit tests in Solr 6 Check for example tests here too: https://github.com/apache/lucene-solr/tree/master/solr/core/src/test/org/apache/solr On Mon, Apr 11, 2016 at 12:24 PM, Shalin Shekhar Mangar < shalinman...@gmail.com> wrote: > Please use MiniSolrCloudCluster instead of EmbeddedSolrServer for > unit/integration tests. > > On Mon, Apr 11, 2016 at 2:26 PM, Rohana Rajapakse < > rohana.rajapa...@gossinteractive.com> wrote: > > > Thanks Shawn, > > > > I am now pointing solrHomeFolder to > > lucene-solr-master\solr\server\solr > > which contains the correct solr.xml file. > > Tried the following two ways to create an EmbeddedSolrServer: > > > > > > 1.
