I think that's the wrong approach. I have to admit I only have read
tests but I don't think many of my models would be compatible with the
test suite deciding which rows to delete. Would it not be possible to do
something like:

auto=gtk_tree_model_auto_test_new_with_model(model);
do_something_which_will_cause_model_to_change();
gtk_tree_model_auto_verify(auto);
do_something_else_which_will_cause_model_to_change();
gtk_tree_model_auto_verify(auto);

perhaps with some advice in the documentation about what kind of changes
would make good tests.

Cheers,

Ali.
