Correct me if I am wrong, before deciding on any usability test,
somethings should be clear such as:
1. what is your goal, what exactly do you want to find out
2. making sure your system/prototype is prepared to test the things you want
3. who would be your user
4. then designing the appropriate experiment such as: deciding the
metodology to use, how you  would carry out your experiment eg. no of
subjects, questions, etc., then how you would analyze the data you get.

As far as I know, this is as general as it gets.
I have run an evaluation for small subject sample in 2 weeks, but of
course it really depends on how many people you take, the usability test
you do and how well you prepare the experiment.

Unfortunately, just as there is no one-test-fits-all usability test for
HCI-UI evaluations, probably there no generic fast & usability test for 
SWUI that you can apply for any type of research question one might have.

Having said that, there are things you can do to save time.
Some pointers:
1. take enough sample, but not excessive if it does not add value to 
answering your questions. On the other hand, be aware that sample which 
is too low gives doubtful results.
2. plan your evaluation well, fail experiment means you might need to 
redo it and that takes time.
3. be aware that the more material you take (video, tape, interview, 
questionnaire) the more time you need to analyze them.
