Comment #16 on issue 688 by pekka.klarck: would like to be able to
associate metadata with a test case
http://code.google.com/p/robotframework/issues/detail?id=688
We decided not to implement this feature, or include it even if it would be
got "for free". The main reason is that tags can already now be used for as
name-value metadata, and adding new feature that adds the same
functionality would add complexity. Showing tags in reports as name-value
pairs, and in general, can be improved, and separate enhancement request
can be submitted about ideas related to that.
If you Bryan really need this functionality, there's nothing stopping you
from creating a custom version of the framework for your users. Then you
don't need to care about keeping the new functionality generic. The only
drawback is that larger refactorings in the framework may break your custom
changes, but larger changes occur only in major releases and the parsing
code is already now pretty stable.
