Rick Hillegas commented on DERBY-4089:
--------------------------------------
Hi Aaron and Kristian,
I think that the jar files are a better default than the classpath. I think
that the tests are more meaningful when they run against the production
configuration (jar files)--and building the jar files does not seem like a big
burden to me. I would go so far as to say that testing against the production
configuration is the only meaningful barrier to checkin. Some tests only run
against jar files (like the autoloading of the jdbc drivers and the automatic
installation of the network security manager). The production configuration
catches tricky packaging issues in which developers forget to update the build
logic to supplement the jars with classes which are loaded by reflection rather
than reference.
> It should be possible to run unit tests right after "ant all"

> Key: DERBY-4089
> URL: https://issues.apache.org/jira/browse/DERBY-4089
> Project: Derby
> Issue Type: Improvement
> Components: Build tools
> Affects Versions: 10.4.2.0
> Reporter: Aaron Digulla
>
> Right now, the property "derby.junit.classpath" is empty by default. There
> should be an ant target which sets the correct classpath to run all tests
> after an initial checkout and "ant all".
> The current situation is very confusing to beginners and people who try to
> build Derby for the first time. For example, when running the tests, I got
> this exception:
> java.lang.ClassNotFoundException: org.apache.derbyTesting.junit.EnvTest
> but that class was there, the file was there, everything was correct.
> Googling for the error didn't turn anything up, either. It took me a while to
> believe that build.xml just wouldn't try to setup a classpath for the tests.
