/*
* Created on Nov 29, 2003
*
* Test the composition of the properties files
* - properties files exist (default, DE, NO, JA)
* - properties files don't have duplicate keys
* - non-default properties files have same keys as the default.
*
* N.B. If there is a default resource, ResourceBundle does not detect missing
resources,
* i.e. the presence of messages.properties means that the ResourceBundle for Locale
"XYZ"
* would still be found, and have the same keys as the default. This makes it not
very
* useful for checking properties files.
*
* This is why the tests use Class.getResourceAsStream() etc
*
* The tests don't quite follow the normal JUnit test strategy of one test
* per possible failure. This was done in order to make it easier to report
* exactly why the tests failed.
