I'm debugging a set of WCF services. Initially, I created some unit tests, but since I'm using threading I often receive "Aborted" or "Stopped" tests without any clear explanation why (this is a known bug in Visual Studio).
I found it extremely challenging to debug the services when I can't even read the log output, so I quickly wrote a custom Assert class and converted all unit tests to console applications. This way, I was able to fix a huge number of simple problems immediately that were hard to impossible before.
So I'm wondering if it is a good idea to write unit tests as (fully automated) console apps first and convert them to real (executes when launching unit tests in VS) tests later.
