Junit test cases of non public class

Question

I have a class as following

package a.b
public class Public_Class{
  public void add(){
    //logic
  }
}
class Non_Public_Class{
  public void subt(){
    //any logic
  }
}
package a.c

Now I want to make test cases of method subt() in "Non_Public_Class".

How can I access that non public class and my test cases are not in the same package?

Answer 1

You should follow the now (more or less) standards for directory structures that tools like maven suggest. Meaning:

You can have

• src/main/java ... and here go all your production code packages
• src/test/java ... and here go all the test packages (which then can have the same names as your production packages)

That allows you to write unit test for "package protected" stuff.
