That is close to what I have in mind.  When we out-source test input
data, we should do the same with the corresponding expected results.  A
unit test case would look something like this.

- read input data from ics file
- read expected result from corresponding file
- perform action under test on input data
- compare result with previously read expected result

I could write the necessary helper functions and then, for a start,
apply this scheme to the "real world" tests in icalendar-tests.el.
