If a class is largely getters and setters and its other methods for 
linear things, then you're right.

However, if there are ANY edge cases and/or errors to be handled, then 
just writing it and incorporating calls for in in the application code is 
likely to bite your bum because (a) unit/system test of the combined code 
module may never exercise all its edge cases due to inadequate test data 
and (c) once a user starts trying something the system designer never 
thought of and generates the edge case, it may take a lot of time and 
effort merely to determine what happened and which module crashed.

Using a test harness will probably save time and effort overall because:
such harnesses are typically very fast to write: once you've got a test 
harness skeleton running, the code needed to interface it to a new class 
is almost a script and the incremental code within that which tests a 
method is 2-4 lines plus the actual method call. Last but not least, its 
dead easy to set up test date that can deal with all normal and abnormal 
inputs AND contains (comments) to show whether each method test in the 
script should succeed or fail and what the expected results should be.

On top of that, once you have a set of tests set up, they tend to be fast 
and easy to run, so its practical, and worthwhile to rerun them after and 
change is made to the class. I have sets of 30-50 regression tests that 
execute in under a second and will, if done properly, inadvertant 
mistakes made when you're in a hurry. 
 
Been there, done that, got the benefits.
