From: Rhino on 17 Mar 2010 23:39 I'm trying to figure out how to write a test case for this code. The code is pretty simple but I can't think of a way to test it with JUnit3. Here's the code: -------------------------------------------------------------------- public ResourceBundle getResources(Locale currentLocale, String listBase) { final String METHOD_NAME = "getResources()"; //$NON-NLS-1$ ResourceBundle locList = null; /* Get the list resource bundle for the current locale. */ try { locList = ResourceBundle.getBundle(listBase, currentLocale); } catch (MissingResourceException mr_excp) { Object[] msgArgs = {CLASS_NAME, METHOD_NAME, listBase, currentLocale.toString(), mr_excp}; msgFmt.applyPattern(locMsg.getString("msg011")); //$NON- NLS-1$ throw new IllegalArgumentException(msgFmt.format(msgArgs)); } return (locList); } ---------------------------------------------------------------------- If the method returned a null ResourceBundle, that would be relatively easy to test for. But if it doesn't find the "listBase" value, it will simply find the next best fit, assuming there is a reasonable alternative and therefore not return null. Any suggestions? -- Rhino --- news://freenews.netfront.net/ - complaints: news(a)netfront.net ---

Think about what you want the method to do - what success really means - then write code to test those criteria. I don't really understand what this method is trying to do, but maybe you could look at the returned bundle and check that it has the right values in? tom -- I need a proper outlet for my tendency towards analytical thought. -- Geneva Melzack |
