Just a small correction: WebTest steps are ant Tasks (ie extends org.apache.tools.ant.Task) BUT they can't live outside a <webtest> ...</webtest> as they need information from it.

Stefan, which version of Ant do you use? Line 373 of Task.java is quite strange for a NPE.

Hi Stepahn

Marc will correct me if I'm wrong ;-)
WebTest steps are not (yet??) ant tasks.
They have a more elaborate life cycle and other hooks.

I think that there is a template to write new steps, appropriately called MyCustomStep, in the doc.zip available at <http://webtest.canoo.com/webtest/doc.zip>, as well as in the release directories.

Happy testing

I've got some problems developing my own Webtest Task. In fact I can't even get an empty-class extending a already finished Webtest-class(like StorePropertyStep) to work.

My ANT Script looks like following:

<target name="test3">
<taskdef name="mytask" classname="javaTestSupport.CommonTasks$AntTest" classpathref="classpath"/>
        <webtest ...>
            <config .../>
            <steps>
                              <mytask />
            </steps>
        </webtest>
    </target>

Following the ANT manual apache-ant-1.6.5/docs/manual/develop.html#writingowntask
following code is working :

public class CommonTasks {
    public static class AntTest extends Echo {}
}

BUT if I now extend any Webtest Class, like:
public static class AntTest extends StorePropertyStep {}
I get an exception:

INFO (com.canoo.webtest.steps.Step) - Message was: java.lang.NullPointerException ERROR (com.canoo.webtest.steps.Step) - Cannot handle unexpected exception in step TestStepSequence at C:\...justATest.webtest.xml:31: with (taskName="steps")

at com.canoo.webtest.ant.TestStepSequence.executeSteps(TestStepSequence.java:43) at com.canoo.webtest.ant.TestStepSequence.doExecute(TestStepSequence.java:31)


How can I write my own Webtest Tasks?
Sincerly,
     Stefan
