Not sure about this TODO, but here it is anyway...
It would be nice to have unit tests for IkiWiki. This would make sure that we don't break things when adding more functionality.
mmm unit tests. --schmonz
Ikiwiki has over 500 tests, most of them of the unit test variety. They are located in the 't' directory and are run by 'make test'. Most of the core ikiwiki functions are covered. Feel free to contribute more.. --Joey done
