For individual packages, I assume that they were tested before release.

I prefer to test just the software I'm working on.

Of course, I have integration tests of my application.

I wouldn't want anyone doing this who wasn't willing to spend the time  
becoming fairly familiar with the setuptools APIs.  The full set of  
packages uses is described by the working set, which is available (or  
obtainable) to the recipe.  To include tests of all dependencies, you  
would include each of the locations from the working set as test  
directories for the test t runner, being careful to avoid system  
packages -- unless you want to test all system packages on which you  
depend too.  Even then, you could get into trouble, as individual  
package tests might not be runnable without additional facilities you  
don't have. For example, some packages might have test dependencies  
that you haven't included.  There is no standard way of specifying  
test dependencies for installed distributions.

In general, I find implicitly including packages for testing is  
fraught with peril.
