svn commit: r232788 - in /xmlgraphics/fop/trunk/test:
java/org/apache/fop/URIResolutionTestCase.java xml/uri-resolution1.fo
xml/uri-resolution2.fo
Author: jeremias
Date: Mon Aug 15 03:45:28 2005
New Revision: 232788
URL: http://svn.apache.org/viewcvs?rev=232788&view=rev
Log:
JUnit Test cases to test URI resolution using custom URIResolvers. They are not yet integrated into the test suite as the second test fails and the first test needs some changes in the code (see TODO).
Added:
xmlgraphics/fop/trunk/test/java/org/apache/fop/URIResolutionTestCase.java (with props)
