I'm trying to mock subprocess.Popen
. When I run the following code however, the mock is completely ignored and I'm not sure why
Test Code:
def test_bring_connection_up(self):
# All settings should either overload the update or the run method
mock_popen = MagicMock()
mock_popen.return_value = {'communicate': (lambda: 'hello','world')}
with patch('subprocess.Popen', mock_popen):
self.assertEqual(network_manager.bring_connection_up("test"), "Error: Unknown connection: test.
")
Module Code:
from subprocess import Popen, PIPE
# ........
def list_connections():
process = Popen(["nmcli", "-t", "-fields", "NAME,TYPE", "con", "list"], stdout=PIPE, stderr=PIPE)
stdout, stderr = process.communicate() # <--- Here's the failure
return stdout
