Re: [Ddtunit-users] DDTUnit

Hi Jan,
sorry for delay of answer. - I had to catch up with work after vacation.
Now to your question. I am not quite sure about it so I will try to =20
describe the functionallity of DDTUnit a bit. And perhaps you can =20
phrase your question more specifically after this.

As stated DDTUnit is a direct extension of JUnit 3.8. That means =20
there exists a base class
 >DDTTestCase extends TestCase (of JUnit)

To provide a mapping from xml resource to test method DDTUnit uses a =20
<cluster>#id, which can be mapped directly to the name of the test =20
class.
-> This is provided by DDTTestCase.initContext().
<group#id> is directly mapped to existing method name of the testclass.

To provide the notion of a testdata set that can be used during one =20
execution of a testmethod (like one call in JUnit) <test id=3D""> was =20=

introduced.
The details of an implicite loop over these testdata sets is =20
implemented in DDTTestCase class.

If you now add a new dataset <test> under <group> tag the method =20
associated to the groupid will be executed the number of times there =20
are <test> provided  - including the execution of setUp() and tearDown=20=

() every time.

So the behavior of a DDTTestCase method with one <test> dataset is =20
equal to the execution of one testmethod under TestCase of JUnit.

Only if you want to define more than one testdataset per testmethod =20
you will see the benefit of using DDTUnit against JUnit.

I hope this will clarify the usage a little bit.

Best regards

J=F6rg
