Hi all,
I've been thinking about this, and I think a two stages approach would
be more effective. The problems are essentially two:
* algs not producing an output with default params
* algs producing incorrect results, with various combination of parameters.
Problem #1 is far more frequent and important than #2, especially
because of changes in the backends, and far easier to spot.
How difficult would it be just to check whether an output (possibly of
the correct type: vector/raster/html) is produced?
This alone would make the environment far more reliable (someone may
have notices the string of tickets raised by our latest analysis course).
All the best.
