addCleanup vs tearDown

Question

Recently, Ned Batchelder during his talk at PyCon 2016 noted:

If you are using unittest to write your tests, definitely use addCleanu

Answer 1

Per the addCleanup doc string:

Cleanup items are called even if setUp fails (unlike tearDown)

addCleanup can be used to register multiple functions, so you could use separate functions for each resource you wish to clean up. That would allow your code to be a bit more reusable/modular.
