Thanks Shalin,
I am now trying to use MiniSolrCloudCluster to create mini cluster in solr 6/7
as below:
MiniSolrCloudCluster miniCluster = new MiniSolrCloudCluster(1,
temp_folder_path, path_to_solr.xml, null);
It throws the following exception:
org.apache.zookeeper.KeeperException$NodeExistsException: KeeperErrorCode =
NodeExists for /solr/solr.xml
at org.apache.zookeeper.KeeperException.create(KeeperException.java:119)
at org.apache.zookeeper.KeeperException.create(KeeperException.java:51)

This is a Zookeeper exception and I cannot figure out what is wrong. Can
someone shed some light please?

Rohana, as I said earlier, the MiniSolrCloudCluster is specifically made for
your use-case i.e. where you want to quickly setup a SolrCloud cluster in your
own application for testing. It is available in the solr-test-framework
artifact.
