Spock test - RESTClient: HttpResponseException: Not Found - spring

Question

I want to write a test for a GET request when the API returns 404.
My test:
def "Should return 404 - object deleted before"() {
setup:
def advertisementEndpoint = new RESTClient( 'http://localhost:8080/' )
when:
def resp = advertisementEndpoint.get(
path: 'api/advertisement/1',
contentType: groovyx.net.http.ContentType.JSON
)
then:
resp.status == 404
}
My error:

You need a failure handler for the underlying HTTPBuilder. From the HTTPBuilder javadoc:
You can also set a default response handler called for any status code
399 that is not matched to a specific handler. Setting the value outside a request closure means it will apply to all future requests
with this HTTPBuilder instance:
http.handler.failure = { resp ->
println "Unexpected failure: ${resp.statusLine}" }
Therefore:
#Grapes(
#Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.7.1')
)
import groovyx.net.*
import groovyx.net.http.*
def restClient = new RESTClient('http://localhost/wrong')
restClient.handler.failure = { resp -> resp.status }
def response = restClient.get([:])
assert response == 404
