Kotlin. Micronaut. TestNG test fails in IDEA but pass via gradle - intellij-idea

Question

I have created sample micronaut project with simple testNG test based on this instruction.
The test works perfectly when I run it via gradle from command line, but fails when I try to run it from IDEA.
For successful gradle run in logs I see routing for my controller:
13:40:44.314 [Test worker] DEBUG i.m.web.router.DefaultRouteBuilder - Created Route: GET /hello -> HelloController#String index() (application/json )
which is missing for IDEA run.
QUESTION: What do I need to configure to make the test also pass in IDEA?

Solved
fixed by setting gradle as test runner as described in http://mrhaki.blogspot.com/2016/03/gradle-goodness-configure-intellij-idea.html

Currently a build tool is required to build Kotlin + Micronaut applications until IntelliJ brings native support for Kapt. This is explained here https://docs.micronaut.io/latest/guide/index.html#kotlin in the section "Kotlin, Kapt and IntelliJ"
