[Casa-framework] test programs

[Ger.VanDiepen at csiro.au]

A test program is more than a .cc file.
Do people now the AIPS++ test environment? I.e. do they know about assay, .run, .in, and .out files?

I think it is good that appsglish does not support unit tests. The DO stuff is (was?) tasking specific. I understood that the old DO-s are now nicely split into a tasking independent proxy class in the library and a thin tasking specific .cc file in appsglish or xmlcasa? Is that indeed true?

Cheers,
Ger

Ok, that sounds like a good solution.  It also keeps the C++ and Python 
test code separated.  Test scripts that call methods in multiple 
components rather than in just one component interface would be better 
candidates for xmlcasa/scripts/test.

As for unit versus regression testing, the Glish and now Python scripts 
were the only tests that systematically called every method in the 
component's interface so I think they are closer to unit than regression 
tests.  None, as in zero, of the old DO's had C++ test code.  In fact, our 
makedefs didn't support unit testing in the old appglish directory 
hierarchy where the DO's lived, which always irritated me.

If we actually stored old output and compared current runs to past runs, I 
would have to agree that we are regression testing.  But that isn't the 
case, at least for the test scripts that I have been dealing with.  I 
intend to make it so for atmosphere, however, so that I can compare 
TELCAL's output with what we get.
