Re: How to test a method which has void return type and no argument?
What 'side effects' does this method have that you are interested in? If
there are none, then it just runs some code and quits and no-one would care
if it did that correctly or not.
There's no return code, so that's not a side-effect?
Does it set any class or global (hopfully not) variables? check those.
Do you want to check the menu for validity? have the method return it and
test it.
From what you've shown us of your method, there's really not much
interesting going on.
Sorry if this sounds cynical,
jim
p.s. As others have said, JUnit's not really up to Gui testing - (though you
could create GUI objects and exercise them with through code if you want to
bother to program the user actions (clicks, text input, etc.).
void CreateMenu()
{
JMenu menuFile = new JMenu("File");
......
}

Hi All,
I am using JUnit for testing java application under Eclipse IDE. I

Could anybody suggest me how do i test this type of method using
JUnit.
well, of course you can only test this kind of method, if it does
something that can be "seen" by the Program. e.g.:
void test() {
MyObject o=new MyObject();
assertEquals(o.getFoo(),"foo");
o.setFooToBar();
assertEquals(o.getFoo(),"bar");
}
If the method does *nothing* at all, it cannot be tested.
Of course, it may be possible that it is a bit more difficult than shown
above, to "read" the result. But that depends on your use-case.
Ciao,

Hi,
Thanks for your reply. I am facing still a problem. Suppose if i
have a method i.e.
class Menu_Bar
{
JMenuBar menubar = new JMenuBar();
JMenuItem File;
JFrame frame = new JFrame();
public Menu_Bar()
{
this.CreateMenu();
...
frame.setJMenuBar(menubar);
}
void CreateMenu()
{
JMenu menuFile = new JMenu("File");
......
}
}
Now could you suggest me how do i test this method i.e. CreateMenu()
which has some local components.
Thanks & Regards
Mohit
