Test Template with Robot Framework cannot use variables - robotframework

Question

I have some problems using the robotframework template,how to get variables passed to the template?
Here is my code:
*** Keywords ***
re-random-value
${random int} = Evaluate random.randint(1, 5)
[Return] ${random-num}
*** Test Cases *** test1
[Template] test template
re-random-value # random-num is return value from keywords re-random-value
*** Keywords ***
test template
[Arguments] ${random-num}
log ${random-num}
when I run the test case test1, The result is re-random-value, not the number of values returned by the keyword re-random-value I expected

The documentation on Robot Framework Test Templates states the following:
... test cases with template contain only the arguments for the
template keyword.
Within the context of a test template an argument can never be a keyword, the approach in the example won't work as is.
Assuming for a moment that the keyword may change per line/test case an intermediate keyword can be constructed that takes the name of the keyword as an argument and executes it. In the below updated version of your example this is what is done. Using the FOR loop to generate multiple values.
*** Test Cases ***
test1
[Template] test template
FOR ${index} IN RANGE 1 5
re-random-value # random-num is return value from keywords re-random-value
END
*** Keywords ***
test template
[Arguments] ${keyword}
${value} Run Keyword ${keyword}
Log To Console ${value}
re-random-value
${random int} = Evaluate random.randint(1, 5) modules=random
[Return] ${random int}
Results in (bear in mind the randomness of the values):
==============================================================================
test1 1
3
2
3
| PASS |
