I am working on software unit tests these days, while I found most results in the web tend to use "unit testing" rather than "unit test". If you search "unit test" in google, you will see "unit testing" from wikipedia.
"Software testing" is also used more frequently than "software test".
From what I can get from dictionary. "testing" means the generic activity, and "test"means every small action in this activity.
Am I right?
test: countable noun A test is a deliberate action or experiment to find out how well something works.
testing: 2. uncountable noun Testing is the activity of testing something or someone in order to find out information.
