Hi
I've just started doing some work on the James project, and I'm looking at
building some new implementations of existing component interfaces. (I've
already contributed a JDBC-backed UsersRepository).
However, I feel a little "unconfortable" doing this without being able to run
tests to ensure that behaviour is the same between different implementations
of the same interface. I set up some JUnit tests for the interface behaviour,
but I'm not sure how to get the components initalised and configured.
Basically, I'd like to set up a framework whereby the test for a particular
component interface would be identical for all implementations, with the
actual test configuration being loaded from an XML config file. (The
initialisation should be limited to the tested component itself and any
dependencies.) Given such a framework, the testing of different
implementations would be pluggable in the same way that the implementations
can be plugged into the real product. This would be a great help, whether
modifying existing implementations, creating new implementaions or comparing
differences (eg performance) between different implementations.
I'm sure that this can be done, but I'm not quite sure where to start. I've
had a poke around the avalon source, and I'm guessing that I'd use the
Excalibur packages? Is there an example demonstrating simple component
initialisation / configuration from an XML file? Better still, is there
already a component testing framework in place?!?
Any help would be appreciated.
Thanks
Daz
