--- Comment #4 from Mariusz_W <mawa...@gmail.com> --- Hi I have some thoughts to discuss. My suggestions for changes. What do you think? "value to shift" - this data should be mandatory. Currently, it is not mandatory in the documentation, but it is also not given what the default value is. Due to the task of the function, it seems that it needs to be specified. https://jmeter.apache.org/usermanual/functions.html#__timeShift test to change: TestTimeShiftFunction.testDefault() And change in docs. "Format" https://jmeter.apache.org/usermanual/functions.html#__timeShift If given, it should be correct. Throw exception if DateTimeFormatter can not be created. test to change: TestTimeShiftFunction.testWrongFormatDate() "value to shift" https://jmeter.apache.org/usermanual/functions.html#__timeShift If given, it should be correct. Throw exception if Duration ( Duration.parse(amountToShift);) can not be created. test to change: TestTimeShiftFunction.testWrongAmountToAdd() -- You are receiving this mail because: You are the assignee for the bug.
