Hi all,

this was discussed before on IRC, but here is an update and a question. currently pytest-trunk implements a convenient new monkeypatch.replace method:

# example usage monkeypatch.replace("os.path.abspath", lambda x: "/abc")

This effectively performs:

import os.path monkeypatch.setattr(os.path, "abspath", lambda x: "/abc")

However, i just wanted to use it and couldn't remember the "replace" name and don't find it very telling anymore. I often do something like this::

monkeypatch.setattr("os.path.abspath", lambda x: "/abc")

As long as the old 3 parameter setattr is not going to be away, that seems fine. Depending on the length of the string I would probably still use the 3 parameter version to get the <TAB> completion on the first argument. Unfortunately just writing

monkeypatch.setattr(os.path.abspath, lambda x: "/abc")

It's actually possible to make this work in many common cases, but is bordering on the magic side. holger
