I fully understand your issue, and I stand by my opinion. I believe 
you're misunderstanding the nature of your problem, your issue is not 
that you want a customized test order execution, but you want a 
customized view of the test result.

That unittest executes its tests in alphabetical order is implementation 
detail for a very good reason, and good unittest practice dictates that 
execution order should never be defined (some even argued that the 
execution order should be randomized). If the test runner turns out to 
execute tests concurrently, that should not cause problems for a 
well-designed test. Displaying the test results in a more convenient 
order for viewing is what you really wanted in 99.99% of the cases.

Fun and easier, perhaps. Except that it solves the wrong problem.
