The code that belongs inside these files is something I will be working
out with Matthew in the near future to round out. I will add an issue
to the issue tracker to facilitate development of this feature.

That is correct, this allows you to execute phpunit from the top level
directory and be able to run your tests with a common configuration.

You got it mostly right. the bootstrap.php here is the phpunit specific
bootstrap. Generally speaking, application code and library code
usually have different API requirements. For example, application code
is part of a larger infrastructure, controllers (and thus controller
tests) are part of the Zend_Controller infrastructure, views part of the
Zend_Controller/Zend_View infrastructure.
As a result, they generally will extend a Zend_Test interface and/or
base test class. But the biggest single difference is that the
placement of files and directories is subject to the application
structure. This means that there is not a logical one-to-one class name
mapping such as you see with library code (like the PEAR naming convention).

Once I get my recent features of Zend_Tool out the door, me and matthew
will explore this (as he is the primary author of both Zend_Application
and Zend_Test, the two components that heavily influence what goes in
these files).
