commit 385b05b3df8e07b4cd589a49c0f348a9541726bd Author: Damian Johnson atagar@torproject.org Date: Thu Jun 14 09:17:25 2012 -0700
Patched mocking.mock() to handle standard library functions
Although standard library functions have the same type as built-in functions, they cannot be mocked using the same setattr approach. To fix this, we patched mocking.mock() to first look for built-in functions, then to handle non-built-in functions with the same type as built-in functions. This will catch standard library functions and mock them appropriately.
This change is an adaptation of one submitted by Erik Islo and Megan Chang. --- test/mocking.py | 25 +++++-------------------- 1 files changed, 5 insertions(+), 20 deletions(-)
