Create an Action Command

Create an action command for asserting that a value is not null. Useable from a test like this:

  <action name="VerifyNoNull" command="java:com.mystuff.MyAssertNotNullValidator"> 
      <param>##{MyValue}</param>  
  </action>    

  package com.mystuff;
  
  import java.util.List;
  import org.mactor.framework.ConfigException;
  import org.mactor.framework.MactorException;
  import org.mactor.framework.TestContext;
  import org.mactor.framework.extensioninterface.ActionCommand;
  
  public class MyAssertNotNullValidator implements ActionCommand {
        public void perform(TestContext context, List<String> params) throws MactorException {
                if (params.size() != 1)
                        throw new ConfigException("Invalid testspec. One parameter requiered: [<the value to validate>]>");
                if (params.get(0) == null)
                        throw new MactorException("Assertions failed. The value was null");
        }
  }

(NOTE: mactor.jar must be in the classpath to compile this code. Include the compiled class in the classpath by editing the MActor start script - testrunner-gui.cmd/testrunner-gui.sh)

Create a Value Command

Create a value command that will generate a random number. Useable from a test like this:

  <value name="ANumber" command="java:com.mystuff.MyRandomNumberGenerator"/>  

  package com.mystuff;
  
  import java.util.List;
  import org.mactor.framework.ConfigException;
  import org.mactor.framework.MactorException;
  import org.mactor.framework.TestContext;
  import org.mactor.framework.extensioninterface.ValueCommand;
  
  public class MyRandomNumberGenerator implements ValueCommand {
    java.util.Random  r = new java.util.Random();
        public String extractValue(TestContext context, List<String> params) throws MactorException {
                return r.nextInt() + "";
        }
  }

(NOTE: mactor.jar must be in the classpath to compile this code. Include the compiled class in the classpath by editing the MActor start script - testrunner-gui.cmd/testrunner-gui.sh)

Create a Message Selector Command

Create a message selector command that will accept any message containing the word 'blue'. Useable from a test like this:

  <message_subscribe name="SubscribeForMessage" channel="Incomingmessage">
    <message_selector command="java:com.mystuff.BlueMessageSelector"/>
  </message_subscribe>

  package com.mystuff;
  
  import java.util.List;
  import org.mactor.framework.MactorException;
  import org.mactor.framework.Message;
  import org.mactor.framework.extensioninterface.MessageSelectorCommand;
  
  public class BlueMessageSelector implements MessageSelectorCommand {
        public void setParams(List<String> params) throws MactorException {}
        public boolean isAcceptableMessage(Message message) {
                  return message.getContent().indexOf("blue")>=0;
        }
  }

Create a Message Builder Command

Create a message builder command that will build a message with a randomly named element. Useable from a test like this:

  <message_publish name="PublishRandomMessage" channel="OutgoingMessage"> 
    <message_builder command="java:com.mystuff.RandomMessageBuilder"/>  
  </message_publish>  

  package com.mystuff;

  import java.util.List;
  import org.mactor.framework.ConfigException;
  import org.mactor.framework.MactorException;
  import org.mactor.framework.Message;
  import org.mactor.framework.TestContext;
  import org.mactor.framework.extensioninterface.MessageBuilderCommand;

  public class RandomMessageBuilder implements MessageBuilderCommand {
    java.util.Random  r = new java.util.Random();
        public Message buildMessage(TestContext context, String templatePath, List<String> params) throws MactorException {
           String nodeName = "a" + r.nextInt() + "b"; 
           return message.createMessage("<" + nodeName +  ">this is the content of the random element " + "</" + nodeName +  ">");
        }
  }
