Hi,

how can I run tests within the [Elasticsearch Java testing framework](https://www.elastic.co/guide/en/elasticsearch/reference/current/testing-framework.html) which require a plugin (specifically [lang-painless](https://github.com/elastic/elasticsearch/tree/v5.4.0/modules/lang-painless))?

I want to use Elasticsearch 5.4.0 but couldn't find any artifact of Painless for that version. Is there an official artifact for Painless I can pull in, like the unofficial [org.codelibs.elasticsearch.module : lang-painless : 5.3.2](https://search.maven.org/#artifactdetails%7Corg.codelibs.elasticsearch.module%7Clang-painless%7C5.3.2%7Cjar)?

painless is running on the server side. Which means that it must run within an elasticsearch node.  
So you probably want to run integration tests here, right?

Yes, I want to use `ESIntegTestCase`.

Any hints how I could add plugins there?

The specific project is [Jest](https://github.com/searchbox-io/Jest) and the code for Elasticsearch 5.3.0 is as follows:

> <https://github.com/searchbox-io/Jest/blob/ba06641cc11ae652cf3eeea5e560dd98e2a5be4a/pom.xml#L318-L323>

I'd start an external elasticsearch cluster.

For example, have a look at the [maven elasticsearch plugin](https://github.com/alexcojocaru/elasticsearch-maven-plugin) which is really nice for that.

Thanks for your reply!

Does `ESIntegTestCase` work with an external Elasticsearch cluster?

If not, that's a change I'd like to avoid for now. Looks like it'll stay on Elasticsearch 5.3.x until there's a (third-party) artifact of `lang-painless` for ES 5.4.0.

It would work, if there was an official artifact for `lang-painless`. 😉

As far as I see, that Maven plugin only supports spawning a single Elasticsearch node but not a whole cluster, is that correct?

Correct. May be you can open an issue so they will see if they can support this or not.  
Although it's a corner case IMO as you would just expect that the cluster is acting correctly whatever the number of nodes you have.

I understand that in your case you want to test things like failover or such.
