<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Is it really required to call testAddAccounts() here? I imagine this is the least effort to setup the ground for your test, but I'd rather extract some part of testAddAccounts() (it tests more than a single scenario, so this should not be a problem) into a new test and use that one.</pre>

Other tests also make use of testAddAccounts() which is why I thought it was advisable to do so. (I also thought it would be better to re-use code which is tested in itself.)</pre>

I also understand why you chose to use testAddAccounts() - that's the fastest way to write the test.
But I don't think this is the best approach. Don't treat this personally - I also think that using testAddAccounts() should be revised in other tests as well, let me explain why:
testAddAccounts() tests several different behavious - around 5, from a brief look at it. Creating an account and verifying it's been created properly is one behaviour, the one you need in your test. But testAddAccounts() does far more than that - it tests 4 more behavious, and none of these are desirable from the perspective of your test. Yet, they are executed upon testAddAccounts() call.
My proposal is to extract the part of testAddAccounts() which creates the first account into a new test method (say testAddAccountSuccessfully(), or sth like that), and reuse that test in testAddAccounts() and your own. Sorry if I didn't make that point clear previously.</pre>

However, in my opinion it's not the best approach possible.
A quote from developerforce.com explains really well why this should be avoided:
"Your unit tests should only test one aspect of your code at a time, so that it is easy to understand the purpose of each unit test. Properly written, and well-decomposed unit tests are an excellent source of documentation. This may mean that you will need to write multiple unit tests in order to fully exercise one method."
