ElasticsearchIntegrationTest

Sorry for the trivial question, but I'm having problems finding this class

ElasticsearchIntegrationTest

If someone could provide the gradle line I would appreciate it.

I've tried this so far, but no cigar:

testCompile "org.elasticsearch:elasticsearch:1.5.1"

testCompile "org.elasticsearch:elasticsearch:1.5.1:test-jar@jar"

Thank You.
