Question

This question arise while trying to write test cases. Foo is a class within the framework library which I dont have source access to.

public class Foo{   public final Object getX(){   ...   } } 

my applications will

public class Bar extends Foo{   public int process(){     Object value = getX();     ...   } } 

The unit test case is unable to initalize as I can’t create a Foo object due to other dependencies. The BarTest throws a null pointer as value is null.

public class BarTest extends TestCase{   public testProcess(){     Bar bar = new Bar();             int result = bar.process();     ...   } } 

Is there a way i can use reflection api to set the getX() to non-final? or how should I go about testing?

Answer 1

you could create another method which you could override in your test:

public class Bar extends Foo {   protected Object doGetX() {     return getX();   }   public int process(){     Object value = doGetX();     ...   } } 

then, you could override doGetX in BarTest.
