Evaluate programmatically conditions in a rule

Hello,

I am developing my own module and I need to test (evaluate) manually all rules corresponding to a specific event.

I used this to get rules attached to my event "my_event" :
$rules = rules_get_rule_set('my_event');

But how can I test the conditions of each rule ($my_rule['#conditions']) ? How can I pass $arguments values to each conditions ?

I tried this, but this does not work.

$arguments = array(
      'arg1' => $arg1,
      'arg2' => $arg2,
      'arg3' => $arg3,
    );
    $state = array(
        'variables' => $arguments,
    );
$result = rules_evaluate_elements($tax_rule['#conditions'], $state);

Thanks for your help.
