             Summary: New DockerSolrServerTestRule that uses TestContainers/Docker
                 Key: SOLR-17653
                 URL: https://issues.apache.org/jira/browse/SOLR-17653
             Project: Solr
          Issue Type: Test
          Components: SolrJ, test-framework
            Reporter: David Smiley


We've got a {{SolrClientTestRule}} abstraction in our test infrastructure that makes it easy for a test to work with Solr in an abstracted sense, using a SolrClient to talk to it.  This issue proposes a new implementation that uses an Http SolrClient (of configurable implementation) to talk to SolrCloud (embedded ZK) running on a single node in a Docker container, and using TestContainers to facilitate the integration.  Future extensibility: the implementation could consider multiple nodes thus multiple containers.  The location of this utility could be a new artifact (JAR) living in the docker module with appropriate dependencies, or just put in solr-test-framework.

This would be extremely useful!  We could then write a hello-world SolrJ SolrCloud test in which Solr is running semi-realistically.  This is all we need for easily adding some backwards-compatibility tests, in either direction (SolrJ 9 to Solr 10, and SolrJ 10 to Solr 9).  Both directions are useful in a rolling upgrade.  Tests using this in our test suite should be demarcated / separated somehow so that running such tests is opt-in, not part of the "check" task.

The addition of this may draw into question the validity/utility of our Docker bats tests, that could perhaps instead be using this.
