Re: [dita] Testing of RNG / DTD / XSD
I'll run the XSDs through some extra parsers tomorrow. There are some differences between Java and C based parsers. Xerces-C is stricter in some cases than it's Java based version. MSXML does not like redefine, but it sometimes finds some other issues. Eric Eric A.

It currently consists of the following components: 1. A set of valid map and topic base documents, at least one per shell, that should be valid against their corresponding shells. These are intended primarily to simply test that the shell document types are parseable (and by extension the modules they integrate) but also contain element and attribute instances that test edge cases or markup new to DITA 1.3 or cases that were incorrect in earlier versions that I wanted to regression test. 2. A set of invalid map and topic base documents, that should not be valid against their corresponding shells. This set is not yet complete--I've been adding to it as I've found valid cases were in fact not valid. I also don't yet have a way to automatically verify that the documents are correctly flagged as invalid (see below). 3. The Ant script build.xml in the doctypes/test/tools directory that does the following: A. Uses the base valid docs to generate grammar-type-specific instances for each grammar type (DTD, XSD URL-based, XSD-URN-based, RELAX NG-URL-based, RELAX NG-URN-based, RNC-URL-based and RNC-URN-based). B. DTD validation using the Ant <xmlvalidate> task. C. DTD validation using Saxon I need both forms of DTD validation because the <xmlvalidate> task fails completely if any DTD is not parseable, while Saxon does not. So between the two I seem to get complete coverage of parsing issues. D. XSD validation using the Ant <schemavalidate> target. This seems to accurately report issues with the XSDs, meaning I don't seem to be getting any false negatives with the currently-generated XSDs. For RNG/RNC the Jing tool, which is the only available Java-based RELAX NG validator that I know of, does not support catalogs, so it's not currently possible to validate the URN-based RNG/RNC documents, shells, and modules. I'm actively working on getting URL-based RNG/RNC validation set up through Ant but it's been a lower priority than XSD generation. It should just be a matter of calling jing from Ant using the Ant <java> task. I've also been doing "unit testing" via direct validation in Oxygen as I work through things, but I've been depending on my automated test suite to validate my work as I do it. I've also set up a Jenkins server on CloudBees that runs these same tests automatically any time anything new is committed under the doctypes/ directory in SVN. This automated regression testing is intended to be a check once the RNG-to-DTD/XSD/RNC is generally proven to be correct so that we can make adjustments to the vocabulary or tools and have them automatically verified in a publicly-visible place. I've set it up to send me email for any failure and it can easily be configured to send email to anyone, including the DITA TC mailing list if appropriate. That is, once we have all the tests passing for 1.3, I think it makes sense to have the automation inform the TC if anything breaks since any breakage would unexpected and bad. Right now the test does a simple log analysis looking for any error or warning message and considers the test to have failed if it finds any error or warning. This analysis could be more sophisticated but this is good enough for now. Additional testing that needs to be implemented include: - Testing correct detection of invalid documents. Unfortunately, with simple parsing plus log analysis for "error" there's no obvious way to treat invalidation of documents as success rather than failure. The approach I've been thinking of is to implement a Java class that essentially inverts the messages from a parser, reporting failure as success and success a failure. This should be easy enough to do. It might also be possible to do it directly in Ant by capturing a log using an Ant log recorder and then applying a different regular _expression_ to the log or transforming the log via text replacement and injecting the result into the final log analyzed. - Adding additional test case documents that exercise more cases and therefore provide more detailed checks of specific content models. These documents are tedious to author. - Implement schematrons that validate the RNGs themselves--George Bina implemented some at the start of his work on DITA RNG but the RNG details have changed since then and I haven't been able to update the schematrons to match. But the schematrons can check many details, including specialization requirements (correct specialization hierarchy, @domains values, etc.). - Use the OT preprocessing as an additional check where the schematrons are not sufficient (not sure what that might be).
