Grails rxGORM rest client

[Magnus Emmoth]

Hi,

I have started to get acquainted with Grails and the plugin rxGORM which is an extension of rx JAVA.

https://github.com/grails/gorm-rest-client

More specifically I am wondering if someone knows how to use the test code that is available.

https://github.com/grails/gorm-rest-client/blob/master/grails-rx-http-client/src/main/groovy/grails/http/client/test/HttpTestServer.groovy

and 

https://github.com/grails/gorm-rest-client/blob/master/grails-rx-http-client/src/main/groovy/grails/http/client/test/TestHttpServerRequestBuilder.groovy

How do I run this code?

Thanks!
