### Question:
ZabbixDataSourceAdaptor implements HostDataSource { public void setClient(ZabbixClient client) { this.client = client; }  static void main(String[] args); @Override eu.ascetic.asceticarchitecture.iaas.energymodeller.types.energyuser.Host getHostByName(String hostname); @Override GeneralPurposePowerConsumer getGeneralPowerConsumerByName(String hostname); @Override VmDeployed getVmByName(String name); @Override List<eu.ascetic.asceticarchitecture.iaas.energymodeller.types.energyuser.Host> getHostList(); List<eu.ascetic.asceticarchitecture.iaas.energymodeller.types.energyuser.Host> getHostList(String groupName); @Override List<GeneralPurposePowerConsumer> getGeneralPowerConsumerList(); @Override List<VmDeployed> getVmList(); List<VmDeployed> getVmList(String groupName); @Override List<EnergyUsageSource> getHostAndVmList(); @Override List<HostMeasurement> getHostData(); @Override HostMeasurement getHostData(eu.ascetic.asceticarchitecture.iaas.energymodeller.types.energyuser.Host host); @Override List<HostMeasurement> getHostData(List<eu.ascetic.asceticarchitecture.iaas.energymodeller.types.energyuser.Host> hostList); @Override List<VmMeasurement> getVmData(); @Override VmMeasurement getVmData(VmDeployed vm); @Override List<VmMeasurement> getVmData(List<VmDeployed> vmList); ZabbixClient getClient(); void setClient(ZabbixClient client); @Override CurrentUsageRecord getCurrentEnergyUsage(eu.ascetic.asceticarchitecture.iaas.energymodeller.types.energyuser.Host host); @Override double getLowestHostPowerUsage(eu.ascetic.asceticarchitecture.iaas.energymodeller.types.energyuser.Host host); @Override double getHighestHostPowerUsage(eu.ascetic.asceticarchitecture.iaas.energymodeller.types.energyuser.Host host); @Override double getCpuUtilisation(eu.ascetic.asceticarchitecture.iaas.energymodeller.types.energyuser.Host host, int lastNSeconds); ZabbixHostVMFilter getHostFilter(); void setHostFilter(ZabbixHostVMFilter hostFilter);  }### Answer:
@Test public void testSetClient() { System.out.println("setClient"); ZabbixClient client = new ZabbixClient(); ZabbixDataSourceAdaptor instance = new ZabbixDataSourceAdaptor(); instance.setClient(client); assertEquals(client, instance.getClient()); }
