Hi,
I have been thinking about testing REST based web services of late. It
occurred to me that these web services are very difficult to test
Really ? My impression is the opposite: a REST-style web service should
be usable by humans and machines alike, which makes them easier to test
(easier then the RPC-style web services, anyway).
against. I was thinking that maybe there is some funky way of mocking a
web service, using XPath and regexes to match on the requst, and use a
templating language to generate the response (based on variables
generated from the XPath and regexes). I was thinking maybe Cocoon 3.0
might help me here.
I think you could do the same with 2.1 or 2.2 as well. I did some
experiments myself and come out with sitemap fragments
like these:
<!--
Intecepts all URIs starting with "api/" and calls the
corresponding
Flowscript function based on the HTTP method. Actually, the
function
name is a concatenation of the last part of the URI and "Set"
or "Get"
depending on the HTTP method.
-->
<map:match pattern="api/*">
<map:select type="request-method">
<map:when test="GET">
<map:call function="{1}Get"/>
</map:when>
<map:when test="PUT">
<map:call function="{1}Set"/>
</map:when>
</map:select>
</map:match>
<!--
Emits as JSON the obj collection object received from Flowscript.
-->
<map:match pattern="apipages/send-json">
<map:read src="module:flow-attr:json"
mime-type="text/javascript"/>
</map:match>
<!--
Emits as XML the obj collection object received from
Flowscript. URI
format is send-{set|map}.xml
-->
<map:match pattern="apipages/send-*.xml">
<map:generate type="jx" src="pages/{1}.jx">
<map:parameter name="obj" value="{flow-attr:obj}"/>
</map:generate>
<map:serialize type="xml"/>
</map:match>
