The Problem
I love Spring, who doesn’t?
One thing however that I found, until recently, a bit awkward was Unit Testing objects which were constructed and initiated via the Spring context and injected into other objects that consumed them. I have seen and used many and varied “bespoke” ways to do this, none of which I found satisfying.
This was until a collegue introduced me to the wonder that is SpringJUnit4ClassRunner. I know, I know, I should have been aware of this ages ago but as they say on millionaire “it’s easy if you know the answer”!

The problem
I was recently working on a JAXB centric app which was required to capture “arbitary” xml. e.g.
<a>
<b></b>
<c></c>
<d>

<maybee></maybee>
<maybef></maybef>

<d />
</d></a>
How could I ever capture the contents of if they could be “anything”?
