HI I have post the same question millions of times I need to test only this one program here is my model classes that is included for this program. Please can someone help me with correct code with no errors and give me a screenshot of the output when testing in JUNIT 4 in eclipse thank you. Please I need it to be done asap I already got the reference part I just need help with the other codes thank you.

Program needs to be test:

package medical.com.medicalApplication.services;

import java.util.ArrayList; import java.util.Collections; import java.util.List;

import medical.com.medicalApplication.model.MedicalRecord; import medical.com.medicalApplication.model.Patient; /** * * This class uses a singleton pattern to mock a service instead of using dependency injection * * In addition, it stores data in memory only using Lists * */ public class MedicalRescordService { private static MedicalRescordService reference = new MedicalRescordService(); private List patients; private List medicalRecords;

public static MedicalRescordService getReference() { return reference; }

public MedicalRescordService() { this.patients = new ArrayList(); this.medicalRecords = new ArrayList(); }

public boolean addPatient(String name, String id) { boolean patientAdded = !patients.stream() .anyMatch(patient -> patient.getId().equals(id)); if (patientAdded) { Patient newPatient = new Patient(name, id); patients.add(newPatient); medicalRecords.add(new MedicalRecord(newPatient)); } return patientAdded; } public MedicalRecord getMedicalRecord(String patientId) { return medicalRecords.stream() .filter(medicalRecord -> medicalRecord.getPatient().getId().equals(patientId)).findFirst().get(); }

public Patient getPatient(String patientId) { return patients.stream().filter(person -> person.getId().equals(patientId)) .findFirst().get(); }

public List getAllPatients() { return patients; } public List getPatientsWithAllergies(String allergyName){ for(Patient patient : getAllPatients()){ if(getMedicalRecord(patient.getId()).getHistory().getAlergies().stream().filter(allergy -> allergy.getName().equals(allergyName)).findFirst().get() != null){ return Collections.singletonList(patient); } } return Collections.emptyList(); } }

Models classes that was included in the project.

package medical.com.medicalApplication.model; /** * This class represent the Allergy model in the application * */ public class Allergey { private String name;

public Allergey(String name) { this.name = name; }
