I have added some checks to make the tests a little more effective at
detecting regressions. I would be grateful if you could have a go at
this yourself next time. If you're not sure how to do this, just ask
on fop-dev.
I was thinking myself that I needed to do something about adding "stuff"
to the <checks> section but have no real idea where to start. I assume
these checks are against the internal area tree? Any way, in the moment
this is still a big black hole for me and I would very much appreciate
any helpful suggestions how I could go best about to achieve some
enlightenment in that area.
The checks are actually against the Area Tree Output. You can generate
it and see what it looks like for any fo by running the following
command line:
fop foo.fo -at foo.xml
There are 2 basic checks you can do (I could be wrong; I'm not the
expect here):
1) <true> check, useful for checking the presence/absence of an element
or attribute in this XML output. It has a single attribute xpath=""
which is just an xpath expression which can select a node in the XML
output.
2) <eval> check, which grabs the value of a attribute specified by the
xpath attribute and checks it matches the expected value specified in
the expected attribute.
As an example I added some checks to your font-size tests to see that a
medium font was in fact 12pt. Internally all FOP's measurements are in
milli-pt, so the check actually looks for the value "12000"
I hope this gives you the basic idea,
Chris
