I really loved the way you started small and got a bit deeper. This is what most people just don't do. You probably know about Gall's law "All complex systems work, are built on top of simpler systems that worked" Hence, if you want to build a complex system, first build a simple system that works and build on top of that.

Great explanation and flow in the video: I find myself sitting with two questions at the end though: 1. Your implementation of the fixture returned one instanciated class. What about if I want to return several values, e.g. environment values, connenction details to databases. How would I return that? Would I return a list of values? Or can I somehow bake it into the function arguments, what information I want to retrieve? 2. I find myself confused on the last part with the Mock module. The way I see it: 1. You instanciate an empty class 2. You call an empty method of this class (none of these fail because both are in fact defined, just have no content) 3. You call Mock to get a value, and you pass in the function to handle the logic. However, the mock_get_item requires an item argument passed to it, yet I do not see you pass anything. Should mock_get_item not receive a list os something that contains the items added to the cart? And in the assertion, you pass in item_database, but the way I read the code, the item_database should still be an empty class since the .get method does nothing yet..
@pixegami Жыл бұрын
Great questions! 1. How do I return a list of values or (anything else) from a fixture? Well, a fixture can return any type of value. So you could have a fixture that returns a tuple. Or you might choose to have a Class or a module that groups together a bunch of different values you want to use together. You are also not limited to using one fixture per test. If you made another fixture called "cart2", then you should be able to use both fixtures in the test by writing: `def test_can_get_total_price(cart, cart2)`. Take a look here for more examples: docs.pytest.org/en/6.2.x/fixture.html 2. You don't see anything being passed in to `mock_get_item` because we never use it directly in the test. We *assign* it to our item_database's "get()" function: "item_database.get = Mock(side_effect=mock_get_item)". Then we call `cart.get_total_price(...)`, which then goes on to call the item_database.get() with our arguments: "total_price += price_map.get(item)": github.com/pixegami/simple-pytest-tutorial/blob/aa65d4b457039dddaeb0a75a359f223a25ec3d09/shopping_cart.py#L23 So when you say " item_database should still be an empty class since the .get method does nothing" - it's actually not true because we *mocked* the get() method to do something for us with this line. We basically 'replaced' the functionality of `item_database.get()`: github.com/pixegami/simple-pytest-tutorial/blob/aa65d4b457039dddaeb0a75a359f223a25ec3d09/test_shopping_cart.py#L42 Hope this helps!

Yup! In unit tests, we don't want to use real databases or values, so we "mocK' them. We're saying "pretend I have a database, and when I query for 'x', give me '5'." This way we can just test that specific unit of the code (usually just a class or a function) without having to worry about the other parts of app.

And what is the case to make test that we now afterwards they gonna pass or fail?
@pixegami8 ай бұрын
When you first write the test, they should fail because in "test driven development" you write tests before the feature. And so you then develop the feature, and if the feature works properly, the test should pass (that's how you know the feature works). In a team environment, you could have different people writing tests and writing features - allowing you to run tasks in parallel. Once the tests are passing, you basically just run the whole suite every time more features get added to the project. It's very common for new features to break something that was developed 6 months ago, for example. So the tests will help detect when that happens, and you can fix it.

I don’t understand how mock_get_item knows that there are two items. It’s only called once, and without any arguments. Item_database is also just a None value. How is that mock return value able to connect these pieces without being told?
@pixegami Жыл бұрын
When you ask "how mock_get_item knows that there are two items" --- what indicates to you that it knows anything beyond what we told it to expect in the code snippet? `mock_get_item` actually doesn't know that there are two items (in the cart). All it knows is that when we call it with "apple", it should return 1.0, and when called with "orange" it should return 2.0. The *cart* itself knows that there are two items in the cart (because we added it), but the cart's database has been mocked with mock_get_item, so no real database is involved. Code for reference: github.com/pixegami/simple-pytest-tutorial/blob/aa65d4b457039dddaeb0a75a359f223a25ec3d09/test_shopping_cart.py#L36-L40

Hi, great video thanks! Could you explain why you didnt or when to use mock.patch instead of what you did here creating an instance of the db and return a mock.
@pixegami Жыл бұрын
Great suggestion! `mock.patch` works too, and is probably a good way to do it. I didn't choose to use it here mainly because I wanted to make the relationship between the mock and the dependency clearer. Introducing mock.patch would introduce some new mental concepts (with it being a decorator), and I didn't want that at this stage in the tutorial. Now, in actual real projects I've used mock.patch before, but it started to become annoying when there's maybe 5-6 things I needed to patch for one test. A lot of nesting, ordinal arguments, and a lot of repetition across various test cases. I am now learning towards fixtures instead, to set up more complex mock behavior.
