test.line() for the full stack

[terrisgit]

I have hooks that listen for test passed and failed events. test.line() returns only two lines - the function and its caller. Usually I need three or four lines of stack. Is this possible? I can't find the API docs for the test object. Thank you.

event.dispatcher.on(event.step.passed, (test) => {
  console.info(test.action); console.info(test.line());
});
