+ * The following would be the steps to test this
+ * 1. Build Oracle database in Docker, please refer below link about how to.
+ *    https://github.com/oracle/docker-images/blob/master/OracleDatabase/SingleInstance/README.md
+ * 2. export ORACLE_DOCKER_IMAGE_NAME=$ORACLE_DOCKER_IMAGE_NAME
+ *    Pull oracle $ORACLE_DOCKER_IMAGE_NAME image - docker pull $ORACLE_DOCKER_IMAGE_NAME
+ * 3. Start docker - sudo service docker start
+ * 4. Run spark test - ./build/sbt -Pdocker-integration-tests
+ *    "test-only org.apache.spark.sql.jdbc.OracleIntegrationSuite"
+ *
+ * An actual sequence of commands to run the test is as follows
+ *
+ *  $ git clone https://github.com/oracle/docker-images.git
+ *  // Head SHA: 3e352a22618070595f823977a0fd1a3a8071a83c
+ *  $ cd docker-images/OracleDatabase/SingleInstance/dockerfiles
+ *  $ ./buildDockerImage.sh -v 18.4.0 -x
+ *  $ export ORACLE_DOCKER_IMAGE_NAME=oracle/database:18.4.0-xe
+ *  $ cd $SPARK_HOME
+ *  $ ./build/sbt -Pdocker-integration-tests
+ *    "test-only org.apache.spark.sql.jdbc.OracleIntegrationSuite"

Review comment:
       super nit: you mean "org.apache.spark.sql.jdbc.v2.OracleIntegrationSuite", right?
