Java Security Exception when inheriting from ESIntegTestCase

[prakharjain17 (Prakhar Jain)]

Hi,
I need to run elasticsearch for my tests, so I thought of using ESIntegTestCase.
But, I am getting this error when am running tests :

java.security.AccessControlException: access denied ("java.lang.RuntimePermission" 
"accessClassInPackage.sun.reflect")
    at java.security.AccessControlContext.checkPermission(AccessControlContext.java:472)

Down the logs, I am getting this error:

REPRODUCE WITH: gradle null -Dtests.seed=A49214270E342DC -
Dtests.class=com.tesco.productservice.elasticsearch.ElasticsearchClientTest -
Dtests.method="test_termQuery_success" -Dtests.locale=tr -Dtests.timezone=Asia/Aden

Resolved it using

-Dtests.security.manager=false

But, now I am getting this error:

NotSerializableExceptionWrapper[class_cast_exception: org.apache.logging.slf4j.SLF4JLoggerContext 
cannot be cast to org.apache.logging.log4j.core.LoggerContext

Close this, I have read all the issues and found out it is better to spin new instances from maven plugin and not use ESIntegTestCase.

What a waste of time!

I request community to remove Testing Column in Elastic search guide and provide a good library for creating local nodes for testing purpose. (I don't use maven and I am having problem to learn maven and convert that plugin to suit my needs)

Some ideas there:

In memory testing with RestHighLevelClient

This will not happen. To do integration tests, you can: Use the Gradle tools elasticsearch already has. You can read some information about this here: #21119. This sample project shows how to use Elasticsearch Test Classes Use the Maven plugin: GitHub - alexcojocaru/elasticsearch-maven-plugin: A Maven plugin to run a single node Elasticsearch cluster during the integration test phase of a build Use Ant scripts like http://david.pilato.fr/blog/2016/10/18/elasticsearch-real-integration-tests-…
