Comment #2 on issue 1670 by pekka.klarck: Executing `Run Keyword` variants
in dry-run mode can fail if keyword name contains variable
http://code.google.com/p/robotframework/issues/detail?id=1670
After little investigation I figured out what goes wrong here.
Background: Robot runs `Run Keyword` variants also in dry-run mode if the
keyword they execute is defined as-is without using variables. This is
because resolving variables doesn't work in dry-run mode in general. Only
some of the variables actually have a value in dry-run and even they may
have wrong values.
The bug: The check to test does given keyword name contain variables is
buggy. It fails if the variable name and its value are same even if the
name would contain a variable. This can be demonstrated with the following
simple example:
*** Variables ***
${name} No Operation
*** Test Cases ***
Works
Higher order fun No Operation
Fails when argument name and value are same
Higher order fun ${name}
*** Keywords ***
Higher order fun
[Arguments] ${name}
Run Keyword ${name}
In the original example ${HIGHER_ORDER_FUN} variable ends up having value
${HIGHER_ORDER_FUN} inside keyword Second and thus it fails for the same
reason. I don't know exactly why that variable gets that value, but it
shouldn't be relevant for this bug.
The fix: The check does a keyword name contain variable just needs to be
fixed. Luckily we have a pretty new utility function for that exact usage
so the fix is very easy.
