ConverterException on functional -war test #1

Open bluesliverx opened 12 years ago

bluesliverx commented 12 years ago

(No JIRA project yet, so I thought I would enter it here) I'm using the plugin in functional testing, and it works great with a typical test-app functional: run, but fails when doing test-app functional: -war. The reason:

org.codehaus.groovy.grails.web.converters.exceptions.ConverterException: Unconvertable Object of class: java.util.LinkedHashMap
org.apache.commons.lang.UnhandledException: org.codehaus.groovy.grails.web.converters.exceptions.ConverterException: Unconvertable Object of class: java.util.LinkedHashMap

The code that is failing is the 'json' declaration of the RestBuilder.put method. I am pretty much following your example, which again works great typically but is failing during functional WAR tests:

def resp = rest.put(url) {
  json {
    param1 = "value"
    param2 = "value2"
  }
}

Not sure if it's because the application is not wired up the same in the functional tests where the app is not in the same JVM? I am using the geb plugin which is providing the functional testing abilities.

I get the same issue when I run tests using -baseUrl. It seems that the DefaultConverterConfiguration is not initialized when targetting a particular server or using -war option.

I did try to initialize DefaultConverterConfiguration but with no luck . The only workaround I have found so far to work is to use "content" instead of "json" and creating "content" using JsonBuilder. This workaround also requires you to explicitly set contentType to "application/json".
