How to test if two dates are different using RobotFrameWork

Question

I wrote a code that calls a webservice twice and recover a date field called : lastLocationDate. In my code I stock the two dates in two different variables date1 and date2 .

Now what I want is to make sure that my two dates are not the same. when I log the value of my dates I have :

Date1=    2019-10-08T06:54:06.118Z
Date2=    2019-10-08T06:54:05.783Z

I tried with substract it didn't work I am trying with not equal and looking for something ilke different.

${DateFinale}=    Subtract Time From Date    ${Date2}     ${Date1}     result_format=%y-%m-%d     exculse_millies=True    date_Format=%Y-%m-%dT%H:%M:%S.%f

I have also tried to add the later Z in the code it dodn't work too

date_Format=%Y-%m-%dT%H:%M:%S.%fZ

I axpected a TimeDate but I got this mesage:
KEYWORD ${DateFinale} = DateTime . Subtract Time From Date ${Date2}, ${Date1}, result_format=%y-%m-%d, exculse_millies=True, date_Format=%Y-%m-%dT%H:%M:%S.%f Documentation:
Subtracts time from date and returns the resulting date.

Start / End / Elapsed: 20191008 09:08:18.494 / 20191008 09:08:18.494 / 00:00:00.000 09:08:18.494 FAIL Keyword 'DateTime.Subtract Time From Date' got positional argument after named arguments.

Answer 1

Shorter version than earlier answer:

Compare Dates Are Different
    ${date1}=    Get Current Date
    ${date2}=    Get Current Date
    Run Keyword If    '${date1}' == '${date2}'    Fail    Dates are same

Answer 2

You could try it this way:

${isdateequal}= Run Keyword And Return Status Should Be Equal ${date1} ${date2} Run Keyword If '${isdateequal}' == 'True' Test Failed

Answer 3

I found a simple way to solve the problem All I had to do is to compare my dates as Strings

    Should Not Be Equal As Strings    ${Date1}    ${Date2}    msg=Aucune localisation n'a été recue 

Thank you for your help

Answer 4

I would use Evaluate Keyword

${date1}=    Convert Date    2019-10-08T06:54:06.118Z
${date2}=    Convert Date    2019-10-08T06:54:05.783Z
${date_same}=    Evaluate    '${date1}' == '${date2}'
Log    ${date_same}
Should Not Be True    ${date_same}
