In order to do unit testing on my Analysis Engines, I would like to

basic JCas object from scratch and set its document text. What is the
correct way to do this?
Thanks for your help!
I'm learning UIMA in a TDL way (Test Driven Learning :) ), and this is
a snippet of a test method:
...
File file = getFile("it/celi/ae/emailAeDescriptor.xml"); //get a
file from classpath
XMLInputSource in = new XMLInputSource(file);
ResourceSpecifier specifier;
specifier =
UIMAFramework.getXMLParser().parseResourceSpecifier(in);
AnalysisEngine analysisEngine =
UIMAFramework.produceAnalysisEngine(specifier);
JCas aCas = analysisEngine.newJCas();
String document= "This is a test document with, this is an email:
[EMAIL PROTECTED]";
aCas.setDocumentText(document);
analysisEngine.process(aCas);
// get annotation iterator for this CAS (Email is my type
FSIndex anIndex = aCas.getAnnotationIndex(Email.type);
FSIterator anIter = anIndex.iterator();
assertTrue(anIter.hasNext());
int i = 0;
while (anIter.isValid()) {
AnnotationFS annot = (AnnotationFS) anIter.get();
assertEquals("it.celi.type.Email",
annot.getType().getName());
assertEquals(mail[i], annot.getCoveredText());
anIter.moveToNext();
i++;
}
......
Take a look to the uima surces and test sources too to learn how to
test uima artifact in isolation.
I hope this could help,

Nice example, Roberto :-)
If you're using Java 5 or later, since the FSIterator is a sub-interface
of the Java Iterator, you can use the Java 5 style of iterating. Here's
an example (not tested - so there may be silly mistakes - if so, please
correct :-) :
// get annotation iterator for this CAS (Email is my type
FSIndex anIndex = aCas.getAnnotationIndex(Email.type);
Iterator<AnnotationFS> anIter =
(Iterator<AnnotationFS>)anIndex.iterator();
assertTrue(anIter.hasNext());
int i = 0;
for (AnnotationFS annot : anIter) {
assertEquals("it.celi.type.Email",
annot.getType().getName());
assertEquals(mail[i], annot.getCoveredText());
i++;
}
