What is the keyword to get time in milliseconds in robot framework? - testing

Question

Currently I am getting time with the keyword Get time epoch , which is returning time in seconds. But I need time in milliseconds , So that I can get time span for a particular event.
or is there any other way to get the time span for a particular event or a testsceanrio?

Answer 1

Check the new test library DateTime, which contains keyword Get Current Date, which also returns milliseconds. It also has keyword Subtract Dates to calculate difference between two timestamps.

Answer 2

One of the more powerful features of robot is that you can directly call python code from a test script using the Evaluate keyword. For example, you can call the time.time() function, and do a little math:
*** Test cases
| Example getting the time in milliseconds
| | ${ms}= | Evaluate | int(round(time.time() * 1000)) | time
| | log | time in ms: ${ms}
Note that even though time.time returns a floating point value, not all systems will return a value more precise than one second.

Answer 3

Using the DateTime library, as suggested by janne:
*** Settings ***
Library DateTime
*** Test Cases ***
Performance Test
${timeAvgMs} = Test wall clock time 100 MyKeywordToPerformanceTest and optional arguments
Should be true ${timeAvgMs} < 50
*** Keywords ***
MyKeywordToPerformanceTest
# Do something here
Test wall clock time
[Arguments] ${iterations} #{commandAndArgs}
${timeBefore} = Get Current Date
:FOR ${it} IN RANGE ${iterations}
\ #{commandAndArgs}
${timeAfter} = Get Current Date
${timeTotalMs} = Subtract Date From Date ${timeAfter} ${timeBefore} result_format=number
${timeAvgMs} = Evaluate int(${timeTotalMs} / ${iterations} * 1000)
Return from keyword ${timeAvgMs}

Answer 4

In the report, for each suite, test and keyword, you have the information about start, end and length with millisecond details. Something like:
Start / End / Elapsed: 20140602 10:57:15.948 / 20140602 10:57:16.985 / 00:00:01.037

Answer 5

I don't see a way to do it using Builtin, look:
def get_time(format='timestamp', time_=None):
"""Return the given or current time in requested format.
If time is not given, current time is used. How time is returned is
is deternined based on the given 'format' string as follows. Note that all
checks are case insensitive.
- If 'format' contains word 'epoch' the time is returned in seconds after
the unix epoch.
- If 'format' contains any of the words 'year', 'month', 'day', 'hour',
'min' or 'sec' only selected parts are returned. The order of the returned
parts is always the one in previous sentence and order of words in
'format' is not significant. Parts are returned as zero padded strings
(e.g. May -> '05').
- Otherwise (and by default) the time is returned as a timestamp string in
format '2006-02-24 15:08:31'
"""
time_ = int(time_ or time.time())
format = format.lower()
# 1) Return time in seconds since epoc
if 'epoch' in format:
return time_
timetuple = time.localtime(time_)
parts = []
for i, match in enumerate('year month day hour min sec'.split()):
if match in format:
parts.append('%.2d' % timetuple[i])
# 2) Return time as timestamp
if not parts:
return format_time(timetuple, daysep='-')
# Return requested parts of the time
elif len(parts) == 1:
return parts[0]
else:
return parts
You have to write your own module, you need something like:
import time
def get_time_in_millies():
time_millies = lambda: int(round(time.time() * 1000))
return time_millies
Then import this library in Ride for the suite and you can use the method name like keyword, in my case it would be Get Time In Millies. More info here.
