Roshan:

JET runs some JET transformations as part of its JUnit suite. Take a look
at.

http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.m2t/org .eclipse.jet/tests/org.eclipse.jet.tests/src/org/eclipse/jet /tests/parser/resources/ResourceTemplateInputTest.java?revis ion=1.1&root=Modeling_Project&view=markup

.... and then ask more questions ;-)

Thanks Paul,

This is the type of test I want to run, but cannot get it to work. I have
a test class that runs this code as the test (I'll make it more robust
once I can get the transformation working in the test). When I run this
test I get the exception below. If I run my transform normally through my
launch file I do not receive any errors and I have output generated.

public void testTransform() throws Exception
{
Map variablesMap = initializeInputs();
IStatus status = JET2Platform.runTransformOnObject("com.tools.transform",
null, variablesMap, new NullProgressMonitor());

assertTrue("setUpAllTests", status.isOK());

try {
ResourcesPlugin.getWorkspace().run(new IWorkspaceRunnable() {
public void run(IProgressMonitor monitor) throws CoreException {
// TODO Auto-generated method stub

}}, new NullProgressMonitor());
} catch (CoreException e) {
fail(e.getMessage());
}
}

Roshan:

A quick look at the NPE suggests it happens if the JET plug-in has not been
started by Eclipse. How are you launching your JUnits?

You should be using an Eclipse launch configuration of type "JUnit Plug-in
Test".

You're right it was a problem with my launch configuration and when I
properly setup my launch to run the correct plugin. I was orignally
running the same transform as my project and so my unit tests were not
running, but changing it to run the org.eclipse.sdk.ide product runs my
transformation and test.

Now I have a different question. On the basis of unit testing I want to
test my xpath. what would you say is a good test for the xpath in the
template snippet below? I was want to use XMLUnit to test because all of
my output is xml.

<c:when test="string($someControl/@attribute1) != 'true'">
<c:setVariable select="$composite_widget/@attribute1" var="myParent" />
</c:when>

Thanks,
Roshan

Roshan:

I'm not an XMLUnit expert, but here's a suggestion on JUnit testing JET
transformation results...

1) Run the JET transformation using a TestSetup extension. See:

http://junit.sourceforge.net/javadoc/junit/extensions/TestSe tup.html

JET uses this technique in some if its JUnits:

http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.m2t/org .eclipse.jet/tests/org.eclipse.jet.tests/src/org/eclipse/jet /tests/parser/resources/ResourceTemplateInputTest.java?revis ion=1.1&root=Modeling_Project&view=markup

2) With a TestSetup, individual tests in the JUnit class can than verify
individual file contents. If you have XML content to verify, the XMLUnit
would be a handy tool.

3) For Unit testing your XPath expressions, one possibility is to create a
template (and a ws:file action) that writes calculated values, and then
write a JUnit test to verify these values. If you don't want this template
run in normal circumstances, you could run it only if a particular XPath
variable is defined, and define that variable when you run the JUnit test.
