Using the Runtime Options dialog box, you can specify that you want to log the elapsed time, the thread number, and the current machine information during execution. This information is then written to the results file where you can display and sort it. For example, if you encounter nested test cases in the results files because you use multi-threading, check this check box to record thread number information in your results file. Then, you can sort the lines in your results file by the thread numbers to better navigate within the nested test cases.
