I found that a good testing framework can lower the barrier of writing
useful tests. Nice logging and status reports are important I feel. And
if for example you can easily write data driven tests, then testing all
possible code paths in a critical area becomes straight-forward and the
tests will remain readable (and with that, maintainable; people tend
forget that every test also adds to the overall maintenance costs which
can often enough outweight the benefits of the test). It's actually the
one thing I really like about Qt's testlib.
If a testing framework even goes so far to allow fuzz testing out of the
box, then you have a nice sanity check for your APIs.
I have no experience in writing a testlib, but I would assume it's a
