Pytest- mock chained call

Asked 2022-Feb-22 at 19:38

I'm trying to mock chained call in pytest (and pytest-mock package), but for some unknown (for me) reason it doesn't work which means I don't get mocked return_value from my mock. It looks like it created object of MagicMock, but without defined return_value. My guess is that it's related to chained call.

The mocker variable is a Pytest fixture. Rather than using imports, fixtures are supplied using dependency injection - that is, Pytest takes care of creating the mocker object for you and supplies it to the test function when it runs the test.

Pytest-mock defines the "mocker" fixture here, using the Pytest fixture decorator. Here, the fixture decorator is used as a regular function, which is a slightly unusual way of doing it. A more typical way of using the fixture decorator would look something like this:

So pytest-mock is a thin wrapper around mock and mock is since python 3.3. actually the same as unittest.mock. I don't know if mocker is another library, I only know it as the name of the fixture provided by pytest-mock to get mocking done in your tests. I personally use pytest and pytest-mock for my tests, which allows you to write very concise tests like

In your case since you are patching the class that is present within the test file itself you would use mocker.patch.object.

Pytest patch fixture not resetting between test functions when using return_value

I have a issue with one of my fixtures, which is doing a patch not resetting between test calls.

The fixture is basically a patch which is wrapper around a object, so I can assert that it has been passed into another function.

The fixture looks like this:

You have been a victim of the common pitfull of mutable default arguments. Each time you set the entities property you in fact change the default value of the entities argument, so the next time a new Entities object will be created with an empty argument, this will be used instead of an empty list.

The usual fix is to use a non-mutable placeholder object as default value:

Sorting imports fails on Python VSCode extension

Asked 2021-Oct-27 at 09:34

Background

I have an anaconda environment that has Python 3.7 installed. I have a file with some imports out of order which I want VScode to order when pressing CRTL+s.

However, instead or ordering the imports, there is a crash and nothing happens.

Problem

When I press CRTL+s on my VScode, I get a pop up saying the Python extension crashes. After some investigation, this is the stack-trace I found:

ANSWER

Answered 2021-Oct-27 at 09:34

Reason

The problem here is that I had broken dependencies which would not allow me to do any updates nor new installs.

This had to do with having packages from both conda and pip. Some of them play nice together, some don't.

Solution

My solution, was unfortunately, rather atomic. I deleted the environment and created a new one with Python 3.7. Upon doing that, I also added an extra conda channel conda-forge which I recommend instead of pip.

Once I did that I installed all the dependencies and packages using conda and it worked.

Commands

Here are the command I used:
