-When the tests are run manually with mvn command on hosted Linux, WebLogic image store/oracle/weblogic:12.2.1.3 is pulled from docker hub or uses local image if one exists. Server jre images are pulled from a local repository wlsldi-v2.docker.oraclecorp.com. Operator image is built with the git branch from where the mvn command is executed.
-All the tests that start with IT*.java in integration-tests/src/test/java are run. The test runs a series of tests and archives the results into jar files upon completion.

+- Operator image is built with the git branch from where the mvn command is executed.

 Operator - constructor takes yaml file with operator properties and generates operator valus yaml with required properties and certs,  creates service account, namespace and calls helm install using the generated values yaml file. Also contains methods to delete operator release, verify operator created and ready, scale using rest api, verify a given domain via rest, verify external rest service, etc  <p>
 Domain - constructor takes Map with domain, LB, PV properties and creates domain crd, LB operator/ingress and PV artifacts using the sample scripts provided in the project. Also contains helper methods to destroy domain by deleting domain crd, verify domain created and servers are ready, deploy webapp, verify load balancing of http requests, etc <p>
