Hi.

In all my test, i've the same error:

Script error executing at: invoke

In something so simple like this

<project name="Config" basedir="." default="main">

  <property name="webtest.home"
location="C:\herramientas_test\Canoo\build" />
  <import file="${webtest.home}/lib/taskdef.xml"/>

  <target name="main">
    <webtest name="myTest">
      <config 
        host="10.252.131.102"
        port="8081"
        protocol="http"
        basepath="eficaz" />
      <steps>
        <invoke 
          description="get Login Page"
          url="" />
        <verifyTitle 
          description="we should see the login title"
          text="Eficaz" />
      </steps>
    </webtest>
  </target>
</project>
