I can see in the dependency injection video , you say the object cannot be
mocked since it's created with that class as it beats the point of unit
testing.
Now lets say,
Person class is changed to support dependency injection (no spring
framework)
Person.java
public class Person(){
Address address
public void Person (Address address){
this.address = address;
}
public String getPersonAddressInfo(){
return address.getInfo();
}
}
I am assuming this should work, meaning we should be able to Mock the
Address obejct ? But lets say the Person object is created in a Request
Handler class. While testing RequestHandler we wont be able to mock the
objects right ? I hope you got my question. How do we handle this ?
RequestHandler.java
public void process (Person person){
Address address = new Address;
person = new Person (address);
person.getPersonAddressInfo();
}
Thanks,
Vikram
