Hi group.

Just wondered... how to write a unit test for something like:

public void fatal(Exception x) {
    x.printStackTrace();
    if (x instanceof DAException)
        JOptionPane.showMessageDialog(null, "Database error. Only barfing ist left..");
    System.exit(1);
}

Ciao, Imi.

in a short answer...mock objects..

A mock dialog so you can test the correct error message was provided and
that the .showMessageDialog() method was called.

A mock System object that you can test that its mock exit() method was
called.
