Subject cvs commit: jakarta-commons/logging/src/test/org/apache/commons/logging/jdk14 CustomConfig.properties CustomConfigTestCase.java DefaultConfigTestCase.java TestHandler.java
Date Sat, 29 Mar 2003 22:04:55 GMT

  Modified:    logging  build.xml
  Added:       logging/src/test/org/apache/commons/logging/jdk14
                        CustomConfig.properties CustomConfigTestCase.java
                        DefaultConfigTestCase.java TestHandler.java
  Log:
  Add a more thorough set of unit tests for using JDK 1.4 logging.  Right now,
  the tests run when everything is in the system class loader -- need to add
  execution wrappers for two-tier class loaders where:
  
    * commons-logging.jar is in the parent and test execution is in the child
  
    * commons-logging-api.jar is in the parent and test execution plus
      commons-logging.jar is in the child
  
  to simulate container environments like that you get running inside Tomcat.
  
  Later on, we'll want an analogous set of tests for Log4J.
