Validar una página web en contra de su tipo de documento (DTD) dentro de un paso Canoo WebTest utilizando un script Groovy

Question

¿Cómo puedo validar una página web en contra de su tipo de documento (DTD) dentro de un paso Canoo WebTest con Groovy?

Answer 1

Actually I know the answer. But as it took me a while to get it working, I thought I'd share my solution. It's a webtest macro. You can also only use the sequential if you like...

<macrodef name="verifySchema" description="Validate the current document against its schema">
<sequential>
    <groovy description="validate schema" >
        import javax.xml.parsers.ParserConfigurationException
        import javax.xml.parsers.SAXParser
        import javax.xml.parsers.SAXParserFactory

        import java.io.InputStreamReader


        import org.xml.sax.ErrorHandler
        import org.xml.sax.InputSource
        import org.xml.sax.SAXException
        import org.xml.sax.SAXParseException
        import org.xml.sax.XMLReader

        class MyHandler implements org.xml.sax.ErrorHandler {
            void warning(SAXParseException e) throws SAXException {
                println 'WARNING: ' + e.getMessage()
            }

            void error(SAXParseException e) throws SAXException {
                println 'ERROR: ' + e.getMessage()
                throw e
            }

            void fatalError(SAXParseException e) throws SAXException {
                println 'FATAL: ' + e.getMessage()
                throw e
            }
        }


            def factory = SAXParserFactory.newInstance()
            factory.setValidating(true)
            factory.setNamespaceAware(true)

            def parser = factory.newSAXParser()
            def reader = parser.getXMLReader()
            reader.setErrorHandler(new MyHandler())
            def response = step.context.currentResponse.webResponse
            reader.parse(new InputSource(new InputStreamReader(response.contentAsStream,"UTF-8")))
    </groovy>
</sequential>

If you want to fail your test on warnings too, add a throw statement to the handler accordingly.
