Testing reports

Well, it would be a start to ensure that reports produced output in a consistent format!  :-)

Once that is achieved, it ought to be possible reliably to define "correct" output based on a template.  (But of course I know nothing of your test environment, so it may not apply to you.  I speak of how I would tackle the problem were it my project ... :-)

The test functions that drive the "make check" tests are in test-core and they are wrapped and accessible from guile. You could surely catch some regressions by expanding those tests.

Moreover, the tests we have don't have a way (AFAIK) to test for the
results of a report.  I think we can test that a report loads.  We might
even be able to test that a report runs.  But I don't think we actually
test the output of the report to make sure that e.g. the report
generates the "correct" output.

I don't know how we could change that.
