I am writing unit tests for my Python and Fabric based code. I have following method which in turn calls sudo
method of Fabric API multiple times with different arguments. I would like to know how to call assert on mock sudo
object.
**main_file.py**
from fabric.api import sudo
def do_something(path_to_file_to_be_copied, destination_path):
# remove file if already exists
sudo('rm ' + path_to_file_to_be_copied, warn_only=True)
sudo('cp ' + path_to_file_to_be_copied + ' ' + destination_path)
I have written test file as below :
**test_main_file.py**
import main_file
class MainFileTest(unittest.TestCase):
@mock.patch('main_file.sudo')
def test_do_something(self, mock_sudo):
file_path = '/dummy/file/path.txt'
dest_dir = '/path/to/dest/dir'
main_file.do_something(file_path, dest_dir)
mock_sudo.assert_called_with('rm ' + file_path)
Above test fails because mocked object remembers only last call. that is, if I write mock_sudo.assert_called_with(cp + file_path + ' ' + dest_dir)
then test fails.
How can I assert both the calls to sudo
?
Try assert_any_call
which asserts whether there has been any call, not just the most recent one.
Or, you can use call_args_list
to get the list of args the mock has been called with.
