### Question:
ProcessManagerStatus { public int getRegistriesCount() { return MicroserviceManager.getInstance().getRegistries().size(); } ProcessManagerStatus(); String getJsonMicroservicesStatus(); String getJsonRegistriesStatus(); int getRunningMicroservicesCount(); ProcessManagerStatus setRunningMicroservicesCount(int count); ProcessManagerStatus setMicroservicesStatus(String microserviceUuid, MicroserviceStatus status); ProcessManagerStatus setMicroservicesState(String microserviceUuid, MicroserviceState state); MicroserviceStatus getMicroserviceStatus(String microserviceUuid); void removeNotRunningMicroserviceStatus(); int getRegistriesCount(); Map<Integer, LinkStatus> getRegistriesStatus(); ProcessManagerStatus setMicroservicesStatePercentage(String microserviceUuid, float percentage);  }### Answer:
@Test public void tstGetRegistriesCount() { assertEquals(0, processManagerStatus.getRegistriesCount()); }
