I have the below method, but I am not able to create a test case for this. Can you please help ?

I dont want to use Mocking.

class A {
    public void setValue(PersonInfo a, Person b){
        if (a.getFullname() == null) {
            b.setFullName(a.getFirstName());
        }
    }
}

I want to see if I set a value for PersonInfo.firstname then whether it's setting as the full name of the Person or not.

Tried the below approach but it's coming as null

class TestClasss{

  @Autowired
  A a;
  public void TestValue(){
    Person p = new Person();
    PersonInfo pi= new PersonInfo();
    pi.setFirstName("TEST");

    a.setValue(pi,p);
  
    assertEqual("TEST",p.getFullName());

}

For this I would write a couple tests:

• Test 1: Create a PersonInfo with a null full name, and a Person with a known full name that's different from the PersonInfo first name. Assert that the Person full name equals the PersonInfo first name.

• Test 2: Create a PersonInfo with a non-null full name, and a Person with a known full name that's different from the PersonInfo first name. Save the Personfull name in a variable. Assert that the Person full name is different from the PersonInfo first name and equal to the value of the variable in which you saved it.

You can do something like below.

@Test
public void testA(){
  A ao = new A();
  PersonInfo a = new PersonInfo();
  a.setFirstName("Name");
  Person b = new Person();
  //call you method here
  ao.setValue(a, b);
  // As values of b object changed in the method so it will be reflected after 
  // method call also 
  // simple assertion... based on your requirement update this assert statement
  Assert.equals(a.getFirstName(), b.getFullName()); 
}

I also tried with same example .. I am getting values. I have attached one screenshot you can also verify.
