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

Another good thing about addCleanup is that it just works as you'd expect.

For example, if you call it in a setUp function, then all test methods will call the cleanup function in the end.

If you call it in a test method, only this method calls the cleanup function.
