Systems and methods for automated determination of error handling. Data is received including one or more procedural operations to be tested. A first test is run on the data to capture one or more first tracebacks, where each traceback is associated with a procedural operation. A determination is made as to whether each captured first traceback is unique, where unique tracebacks are added to a unique traceback list. An error condition is simulated on each unique traceback on the unique traceback list by running a second test. The second test is run once for each unique traceback. One or more second tracebacks are captured during each run of the second test. When a unique traceback being tested matches a captured second traceback, an error code is returned and the second test may be run to completion. Errors encountered during each iteration of the second test running to completion are identified.
