Vemund Østgaard updated DERBY-3445:
-----------------------------------

    Attachment: 3445-singletest-diff
                3445-SysinfoLocaleTest-diff

Thank you all for the comments and suggestions, I've added two more patches based on the feedback.

3445-SysinfoLocaleTest-diff has a fix for the bug pointed out by Dan.

3445-singletest-diff is a response to Thomas' wish for a way to run a single test with EMMA
using ant.
- Added a task <junit-single> which is in turn used by a task <emma-single>. Both
need the property derby.junit.testclass set to some classname that will be attempted run as
a junit test/suite.

So, doing: 
"ant emma-single -Dderby.junit.testclass=org.apache.derbyTesting.functionTests.tests.tools.SysinfoLocaleTest"

should run that particular test with codecoverage.

I also changed my use of ${junit} to ${javatools.dir}/junit.jar, as the first property is
set in tools/ant/extrapath.properties and those properties are only loaded for compilation
and not when just running a junit test.

I'll write up some information on what you need to test with EMMA and how to use the new junit
and emma targets, probably on monday. I guess I will add some info to the junit wiki page
and perhaps a new page for EMMA, and add some more explanations to the build.xml file.

> It is a bit tricky to use EMMA to measure code coverage for the derby testing.
> Modifications must be made to the source both to avoid problems with the SecurityManager
and individual tests. It would be good if these modifcations could be done once and for all
so that it was easier for anyone to run the tests with EMMA.
> It would also be good to have ant tasks that would make it even easier to run the tests
with EMMA.
