I've been working on taking the DOM Level 1 tests,
written in Java and ECMAScript, and defining the
test scenarios using XML.  I've already written a
stylesheet to take the test scenario's file and translate
them into a set of Java methods to test a variety of
interfaces.  Next, I'm going to try to
write a stylesheet to produce ECMAScript tests --
if I can get this to work, I feel fairly confident that
we could do the same for any other bindings, so that
we would have one set of common test scenarios, and generated tests for each
binding.  I'll forward real
examples early next week, but the basic idea is to set up
a set of ENTITY definitions for each binding and a
conditional include that toggles between various bindings.

Within the XML file, the test scenarios are defined like so:

<TEST ID="test_name" CATEGORY="category name"  INTERFACE="interface name>
<DESCRIPTION> test description goes here </DESCRIPTION>
<EXPECTED RESULTS> expected results go here </EXPECTED RESULTS>
<CALL NAME=&idlname; TYPE=&return_type; > describe what you want to do in
this step
<PARAM VALUE="parameter value" />
   zero or more of these

.... there may be a series of calls for this test scenario ...


We've successfully generated several tests already for all of the
some more work to do on the DTD to handle additional cases, but this
approach looks
promising.  As it currently stands, the XSLT file is only 65 lines of code!
I don't expect that
it will be more than a couple of hundred before I'm through.  So, I expect
that generating
similar transformations for additional languages will be trivial.
