Cannot get an exception's stack trace via ExceptionResult class

[jinlxz]

Hi,

I designed a custom class A implemented the class TestSystemListener , I can't get the stack trace of an exception in the override method testExceptionOccurred, my code is as follows:

	@Override
	public void testExceptionOccurred(Assertion assertion, ExceptionResult exceptionResult) {
		// TODO Auto-generated method stub
        String message = (exceptionResult.getMessage()==null)?"":exceptionResult.getMessage();
      // xmlnode is an instance of class org.w3c.dom.Element
        xmlnode.setAttribute(ATTR_MESSAGE, message);
	}

the variable message is always empty when executing some test case with exception, also methods getActual() and getExpected() of class TestResult return null, I suppose they can return some useful information, exceptionResult.getMessage() returns the stack trace and the previous 2 calls return the expectation and actual result in the test, is it a bug of Fitnesse?

Can you help me with these issues?

Thanks.

Hi Liu, I think I had the same or similar problem and fixed it in PR #1131 for the standard HTML output. See https://github.com/unclebob/fitnesse/pull/1131/files In file src/fitnesse/testsystems/slim/HtmlTable.java New line number 374 ... exceptionResult.getException() If I remember correctly either exceptionResult or TestResult are populated but not both. So if you have an exception the methods getActual() and getExpected()  have no defined values. Hope this helpes.

Thank you six42.

I fixed it, I converted the instance of class ExceptionResult to that of class SlimExceptionResult and invoked the method getException() on it, it returned the stack trace successfully.

Glad that I could help. Enjoy FitNesse.
