Junit test : what am i doing wrong here? Please fix my test code

+GetSet added

aa.java

ArrayList list = new ArrayList<>();

GetSet set;

Scanner scan = new Scanner(System.in);

Selection selection = new Selection();

public void add(GetSet obj)

{

obj.setFirstName(selection.prompt_FirstName());

obj.setLastName(selection.prompt_LastName());

obj.setStreet(selection.prompt_Street());

obj.setCity(selection.prompt_City());

obj.setState(selection.prompt_State());

obj.setZip(selection.prompt_Zip());

obj.setPhone(selection.prompt_Telephone());

obj.setEmail(selection.prompt_Email());

set = new GetSet(obj.getFirstName(), obj.getLastName(), obj.getStreet(),

obj.getCity(), obj.getState(), obj.getZip(), obj.getPhone(), obj.getEmail());

list.add(set);

System.out.println(set.toString());

System.out.println(" Done!");

}

Selection.java

public String prompt_FirstName() {

System.out.println("First Name:");

while (!scan.hasNext("[A-Za-z]+"))

{

System.out.println("Invalid. " + "First Name: ");

scan.next();

}

String firstName = scan.next();

return firstName;

}

and other prompts are just like above.

GetSet.java

 public class GetSet { private String firstName; private String lastName; private String street; private String city; private String state; private int zip; private String phone; private String email;  public GetSet() { firstName = ""; lastName = ""; street = ""; city = ""; state = ""; zip = 0; phone = ""; email = "";  public GetSet(String firstName, String lastName, String street, String city, String state, int zip, String phone, String email) { this.firstName = firstName; this.lastName = lastName; this.street = street; this.city = city; this.state = state; this.zip = zip; this.phone = phone; this.email = email; }  public void setFirstName(String firstName) { this.firstName = firstName; }  public String getFirstName() { return firstName; }  public void setLastName(String lastName) { this.lastName = lastName; }  public String getLastName() { return lastName; }  public void setCity(String city) { this.city = city; }  public String getCity() { return city; }  public void setStreet(String street) { this.street = street; }  public String getStreet() { return street; }  public void setState(String state) { this.state = state; }  public String getState() { return state; }  public void setZip(int zip) { this.zip = zip; }  public int getZip() { return zip; }  public void setPhone(String phone) { this.phone = phone; }  public String getPhone() { return phone; }  public void setEmail(String email) { this.email = email; }  public String getEmail() { return email; }  public String toString() { return "First Name: " + firstName + " Last Name: " + lastName + " Street: " + street + " City: " + city + " State: " + state + " Zip: " + zip + " Email: " + email + " Phone Number: " + phone +" "; } }

Here's my test case

@Test

public void testAddAddress()

{

AddressBook ab = new AddressBook();

GetSet ae = new GetSet("Demian", "Rice", "5053 Apple ave",

"New York", "NY", 10020, "212-212-2121", "drice5053@fmail.com");

assertEquals(ab.add(ae), ae.toString());

}
