I normally rename the test logs to include e.g. a version number for the application tested like this example:
Basic API test - 06-09-2016 - 5.3.01.02
Basic API test - 07-09-2016 - 5.3.03.03
Basic API test - 06-09-2017 - 6.2.103.1102
Basic API test - 07-09-2017 - 6.2.103.1103 .. and so on ...
It would be really nice to be able rename the test logs direct from the script, as a last step (or first) step after the test have completed.
Example attached.
