# Days 66 page related to doctests

For some doctests (hopefully few of them) tests are very long to run. For example, there is a dramatic

TestSuite(R).run(elements = [R.random_element() for i in range(3^6)])

In `sage/rings/padics/padic_base_leaves.py`

Plan of attack:

run

`sage -t`and`sage -t --long`on all Sage files- sort the running time in decreasing order
- start the list from the begining, read the file and try to do faster tests
