Why are comments enabled on my content types in Simpletests? When I run Simpletest, it's showing comment forms at the bottom of all the nodes, even though I don't even have the comment module enabled, nor permissions assigned for it. These comment forms showing up in tests is interfering with my tests and I need to disable them, but I don't know how since I never enabled them in the first place.
module_disable(array('comment')); inside setup() does the trick.
