Hey Daniel,

welcome to this years GSoC. I'm looking forward to work with you on calc.

Depending on your editor ctags and cscope are quite helpful and

For our calc filters-test framework I once wrote a short description
for the wiki that can be found at
. You'll find all the test code at sc/qa/unit/filters-test.cxx and
sc/qa/unit/subsequent_filters-test.cxx and some helpful parts in
sc/qa/unit/helper. For your case it should be enough to create a test
file add the necessary test code to subsequent_filters-test.cxx and
create a csv file containing the expected content.

Please feel free to ask any questions you have for this here or on IRC.
