It is most often a big plus even if in our case it's a long term task.

I am not an expert but to optimize this effort I propose to prioritize
the work. For example, let app maintainers (or generally those that
know given code best) to identify how important unit tests are for
given class or file.

See the guideline #24 here: http://geosoft.no/development/unittesting.html

If someone would like to come with a technical facility for priorities
it would be ideal e.g. using magic line in a comment near class
declaration. But it can even work using a simple wiki page.
See "Running Unit Tests by Priority" at
http://geekswithblogs.net/jakob/archive/2009/06/03/tfs-team-build-2010-running-unit-tests.aspx

A class that 1) implements nontrivial algorithm, 2) is a part of core
library or plugin would have higher priority for test coverage.
The idea could be also to assign higher priority with factor 1.0 and
factor 0.5 or so for lower priority. I would even cheat setting 0.0
for generated code consisted of only setters and getters.

Then perhaps the coverage reports would show more realistic results.

PS: At least I am thinking about assigning various priorities unit
tests for clases of the Predicate lib and Kexi...
