There are a lot of issues involved with letting the tests write to the
file system.  If writing to the file system is needed, then the
temporary filenames should be generated by the framework.  However, even
these could not be supported by browser based implementations.  I'm
pretty darn curious about what would be considered a DOMOutputStream on
an ECMAScript implementation.


Ok, so for the framework you suggest testing DOMWriter using pipes
by creating an inputstream from an outputstream ?

I guess I can live with that.

We probably can skip this, see above.

This is typically used to do weak tests on e.g. pretty print. Since pretty
print is weakly defined you would probably fall back to test whether the
output has a different size than the input after applying pretty-print.
I know this isn't great but it's probably the best you can do.

If we use strings and read from the outputstream I can do it with
String.length().

No, DOMInputSource can have both a DOMInputStream as a DOMReader as an input.

If we just use strings in tests we won't be able to test System
Exceptions. It is currently still an open issue whether System Exceptions
are passed on and how. If this will be done by a DOMException than it
makes sense to build a test for it (something like parse a non existing
file and find out whether a DOMException is thrown).
