That would be great by me. I've always thought that test suites should be
a standard part of SRFIs, and now, with SRFI-64, we have the foundation to
start doing so. What better place to start?

That'd be cool, if you get a chance. The latest one tickles some
ambiguities in the spec, too.

It's not portable at all, although that would be nice.
Currently, it's generated in two steps. I have a test-runner which
generates an XML summary (using SXML internally and then writing out XML)
[source code:
<http://axis.rscheme.org:7973/src/file/view/lib-1/HEAD/srfi/64/xmlrunner.scm>]
and then the web server converts it into HTML on the fly (again, mostly
SXML crunching, but there also using RScheme's xpath facility).
As you say, the line-number stuff is highly non-portable (I even had to
drop a quick hack in RScheme to get the line # that a form *ends* on), but
the runner in theory could just extract that using the test results alist.
More crucially, there does not seem to be any way for a portable runner to
keep track of the nesting of test suites. I'm not sure yet what to
suggest for SRFI-64 to track suite nesting, but something along the lines
of a `test-runner-on-suite-begin!' and `test-runner-on-suite-end!' would
probably do it (*).
In my implementation, the default runner keeps track of all results all
the time, complete with nesting structure, and so when I'm dumping the
results it's easy to walk the test-result tree using my internal data
structure.
[*] do you want to call these things "suites" or "groups"? The
terminology seems to vary from place to place, or am I still missing
something....
