Grails3 controller integration test case fail: No thread-bound request found

Question

With just simple following controller action spock integration-test. Here is my Test.

@Integration
@Rollback
class TestControllerSpec extends Specification {

    def setup() {
    }

    def cleanup() {
    }

    void "test something"() {
       setup:
        def c = new TestController()
        c.index()
        expect:
        c.response.contentType !=null
    }
}

getting following Exception

java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

I've been doing this and it seems to work fine:

Add field:

@Autowired
WebApplicationContext ctx

In setup(): GrailsWebMockUtil.bindMockWebRequest(ctx)

In cleanup(): RequestContextHolder.resetRequestAttributes()
