cvs commit: jakarta-commons-sandbox/jelly/src/test/org/apache/commons/jelly/mock suite.jelly TestJUnit.java service.jelly

jstrachan    2002/09/05 09:44:38

  Added:       jelly/src/test/org/apache/commons/jelly/mock suite.jelly
                        TestJUnit.java service.jelly
  Log:
  An example unit test showing the use of Mock Tags to test a (non existent) web service and a database.
  
  We use Mock Tags to mimick what the SQL and web service tags should do and unit test that they are called correctly.
