### Question:
MoleWebApi { public static String instructInstance(String missionHandle,String strandId, String commandName){ return format(INSTANCE_HEADER + "%s/%s/instruct/%s", missionHandle,strandId,commandName); } private  MoleWebApi(); static String missionRepresentationUrl(String missionName); static String missionParameterDescriptionUrl(String missionName); static String instanceStatesUrl(String missionHandle); static String instanceOutputsUrl(String missionHandle); static String instanceRepresentationsUrl(String missionHandle); static String instantiateMission(String missionName); static String instructInstance(String missionHandle,String strandId, String commandName); static String instructRootInstance(String missionHandle, String commandName); static String instructBlockInstance(String missionHandle, String blockId, String commandName); static String instructMission(String missionHandle, String commandName); static final String MISSION_HEADER; static final String INSTANCE_HEADER; static final String MISSION_NAME; static final String MISSION_HANDLE; static final String STRAND_ID; static final String COMMAND_NAME; static final String BLOCK_ID; static final String MISSION_REPRESENTATION_PATH; static final String MISSION_PARAMETER_DESCRIPTION_PATH; static final String INSTANCE_STATES_PATH; static final String INSTANCE_OUTPUTS_PATH; static final String INSTANCE_REPRESENTATIONS_PATH; static final String INSTANTIATE_MISSION_PATH; static final String INSTANCE_INSTRUCT_PATH; static final String INSTANCE_INSTRUCT_ROOT_PATH; static final String INSTANCE_INSTRUCT_BLOCK_PATH; static final String INSTANCE_INSTRUCT_MISSION_PATH; }### Answer:
@Test public void instructInstance() { Assertions.assertThat(MoleWebApi.INSTANCE_INSTRUCT_PATH).isEqualTo("/instance/{missionHandle}/{strandId}/instruct/{commandName}"); Assertions.assertThat(MoleWebApi.instructInstance("myMissionHandle","myStrand","RUN")).isEqualTo("/instance/myMissionHandle/myStrand/instruct/RUN"); }
