The issue that I always have with all-XSLT testing frameworks is that
they're good for the feel-good cases of testing that you get the right
output for the right input, but not so good for testing that you get the
right result for the wrong input if the right result is <xsl:message
terminate="yes"/>.
If the test framework is also XSLT, it's going to die when the
stylesheet under test dies. I can't tell what CoherentWeb would do.
CoherentWeb is essentially just a multi-threaded batch XSLT test
harness that iterates through the selected XML test files arranged
within a directory structure, performs an XSLT transform and
aggregates all results. Any terminations are highlighted as XSLT
errors (with a displayed running count) but they're designed in and
don't interrupt the batch process.
Its probable that the a modified XSPec XSLT implementation would be
needed to take full advantage of the way CoherentWeb works. For
example, each scenario within a description could be automatically
extracted, with context, into a separate test case file and nested
scenario files grouped hierarchically within a directory structure.
I'm a committer for both Juxy and XSpec. XSpec is good, and my clients
that are primarily XSLT users prefer it because it's just XSLT, but Juxy
can cope with <xsl:message terminate="yes"> because, as a Java
application with Java and XML syntaxes for tests, it can catch the fact
that the transform terminated and then continue on to the next test.
I haven't come accross Juxy, so I will take a look. The sequential
nature you describe: waiting for one test to complete before
commencing the next, provides the potential for the output of one test
to be fed into the input of the next test, at the cost of some
performance. Whilst chaining tests in this way could reduce the
overhead in setting up the tests I can see some drawbacks also.
