Pass parameters to a get with spring mvc test

I am using spring rest docs to generate the documentation of an API. My problem is that inside the get I have some objects which are created from other ones, so I need to mock these objects with are the base to create others ones. I'm not pretty sure how can I achieve that. This is what I am doing now:

My Controller looks like this:

import com.espn.api.platform.model.*
import com.espn.csemobile.espnapp.context.*
import com.espn.csemobile.espnapp.context.common.RequestBasedSWIDContext
import com.espn.csemobile.espnapp.context.common.RequestBasedSeeAllContext
import com.espn.csemobile.espnapp.context.common.RequestBasedUIDContext
import com.espn.csemobile.espnapp.models.browseplayer.BrowsePlayerResponse
import com.espn.csemobile.espnapp.services.browseplayer.BrowsePlayerServiceRepresentable
import com.espn.csemobile.espnapp.services.browseplayer.contexts.RequestBrowsePlayerContext
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.stereotype.Controller
import org.springframework.web.bind.annotation.GetMapping
import rx.Single

@Controller
@ProductApi(
        id = "v1_browse_player",
        title = "Browse Player (v1)",
        description = "")
class BrowsePlayerController(private val transaction: Transaction,private val apiRequest: ApiRequest) {

    @Autowired
    lateinit var browsePlayerService: BrowsePlayerServiceRepresentable

    @GetRequest(
            path = "/v1/browse/players",
            timeToLive = 300,
            queries = [
                QueryParameter(name = "swid", required = true),
                QueryParameter(name = "uid"),
                QueryParameter(name = "seeAll", type = java.lang.Boolean::class),
                QueryParameter(name = "lang", required = true),
                QueryParameter(name = "region", required = true),
                QueryParameter(name = "version", required = true, type = Integer::class),
                QueryParameter(name = "appName", required = true),
                QueryParameter(name = "platform", required = true)
            ]
    )
    @GetMapping()
    fun processBrowsePlayerRequest(transaction: Transaction, apiRequest: ApiRequest): Single<BrowsePlayerResponse?> {
        val applicationContext = RequestBasedApplicationContext(apiRequest)
        val standardContext = RequestBasedStandardContext(
                RequestBasedVersionContext(apiRequest),
                applicationContext,
                RequestBasedEditionContext(apiRequest, applicationContext),
                RequestBasedPlatformContext(apiRequest),
                transaction
        )
        val swidContext = RequestBasedSWIDContext(apiRequest)
        val uidContext = if (checkUIDPresent(apiRequest)) RequestBasedUIDContext(apiRequest) else null
        val seeAllContext = RequestBasedSeeAllContext(apiRequest)
        val requestBrowsePlayerContext = RequestBrowsePlayerContext(standardContext, swidContext, uidContext, seeAllContext, apiRequest)
        return browsePlayerService.getEntitiesBrowse(requestBrowsePlayerContext)
    }

    private fun checkUIDPresent(apiRequest: ApiRequest): Boolean =
            apiRequest.parameters["uid"] != null
}

The issue is for example when I want to create this object: val swidContext = RequestBasedSWIDContext(apiRequest) which depends from the apiRequest one.

My test is just like this:

import com.espn.api.platform.model.Transaction
import com.espn.csemobile.espnapp.context.StandardContext
import com.espn.csemobile.espnapp.context.common.SWIDContext

import com.espn.csemobile.espnapp.models.browseplayer.*

        items.add(buildSport("NCAA Basketball", "s:40~l:41", "http://a.espncdn.com/redesign/assets/img/icons/ESPN-icon-basketball.png"))
        return items
    }

    private fun buildSport(label: String, uid: String, image: String): EntityBrowse {
        val type = "internalLink"
        val url = "sportscenter://x-callback-url/showPlayerBrowse?uid=$uid"
        val action = BrowsePlayerAction(type, url)
        return  EntityBrowse(label, UID.create(uid), action, image)
    }

I'm not really now how can I send the transaction and apiRequest mocked objects to the controller because I am only calling this.mockMvc!!.perform(get("/v1/browse/players/{transaction}{apiRequest}",transaction,apiRequest) without send any param.

Any ideas?
