Modified: framework/src/test/share/org/apache/cactus TestAll.java
Added: framework/src/test/share/org/apache/cactus/util
TestUniqueGenerator.java
Removed: framework/src/test/share/org/apache/cactus/util
UniqueGeneratorTest.java
Log:
- the Cactus convention for test classes is TestXXX, not XXXTest
- add tests to ensure that different test case instances and different test methods
result in unique IDs
- add the UniqueGenerator test to the test suite
