When I use unittest in python, I get the error message:



test_update() missing 1 required positional argument: 'mock_stdout'


Below is my code for test_update:



def test_update(self, mock_stdout):
"""Test update information"""
new_geo="CANADA"
new_commodity= "SUGAR"
new_value = "7.81"
new_ref_date = "2018"
new_vector ="v1574617"
new_coordinate = "1.49"
update = Modify()

with mock.patch(
'builtins.input',
side_effect=[new_ref_date, new_geo, new_commodity,
new_vector, new_coordinate, new_value]):
update.update()
self.assertEqual(
mock_stdout.getvalue(),
"Update information for databasen" +
"3 row(s) updatedn" +
"|2018|CANADA|SUGER|v1574617|1.49|7.81|n" +
"|2018|CANADA|SUGER|v1574617|1.49|7.81|n" +
"|2018|CANADA|SUGER|v1574617|1.49|7.81|n" +
"========================================n")

          As mentioned in this answer to the question Python unittest passing arguments, the problem here seems to be that you are trying to pass in a mock_stdout argument to the function (def test_update(self, mock_stdout):). Try moving the definition of mock_stdout to outside the function, like this:



          mock_stdout = <fill this in>


          def test_update(self): # Removed mock_stdout from the list of arguments
          ...
