The tracing feature built into DTF allows you to easily be able to trace all of the actions that are executed at runtime as well as any property resolving that happens at runtime will be printed. Turning this on is as easy as setting the property dtf.tracing to true and results in the appearance of the following type of log lines:

                   Trace           - EXEC main If {} at tests/ut/if.xml:100:9
                   

The above line shows that the tag If was being executed by the thread "main" and that this action came from the line 100 from the test at tests/ut/if.xml. The {} brackets don't contain any properties because the If tag doesn't have any properties associated with it.

                   Trace           - PROP main If "${test1}" to "true"
                   

The above line shows a property being resolved in the string ${test1} and that the result is true. We currently only show the values of the properties that are resolved because this way you can easily tell if a property was used by a previous tag or not.

This feature can be extended to include other information in the near future but for the time being lets keep this simple enough that any new user to DTF can easily understand what is going on in their test when things are not running as expected.
