Python unit testing - pytest fixtures

This tutorial covers a powerful feature in pytest framework called fixtures. It leverages the dependency injection concept for setup and teardown of your unit tests. It is preferred over traditional xunit style setup/teardown methods. The video explains demonstrating problem, issues with test case in the case of code repetition, creating expensive DB connection in every test case and solving problems with fixtures.

Topics that are covered in this Python Video:
0:00 Overview
0:16 Demonstrating problem
3:25 Issues with test case 1. code repetition 2. creating expensive DB connection in every test case
4:32 Setup and teardown methods
7:05 Solving problem with fixtures
9:24 fixtures leverage a concept Dependency injection

This is probably the most effective pytest fixtures tutorial I have encountered. You've just made my job a lot easier. Thank you. Your python video series is top notch.

4 years old and the best video I've seen on fixtures

There's a lack of pytest video tutorials, and though you haven't covered too many of the pytest features, I'm grateful for the ones you've done so far. Keep it up!

You can also use '-s' which is short for '--capture=no'

Thanks for the great video. One thing to consider, when using fixture with scope="module": You should only test methods of your class that do not modify the object returned by the function, cur in your case (for example a method that adds an attribute to the object). The reason is that you want your tests to be independent, which is not possible, if the test modifies the object that is used in another test.

Best tutorial for fixtures. Smart use of generator.

You are a life saver. I was struggling to understand fixtures. Thanks!

Amazing video. I am new to Python and was finding it difficult to understand fixtures. The initial section of the video set up up the context nicely in terms of the motivation behind fixtures. Finished it nicely with the optimization in the end by using module scope and cleaning things up. Thanks.

I love this: thank you! I spent 30 minutes trying to understand fixtures from some pages I read but your video even at double speed gave me a whole lot more. 7 minutes very well spent!

Excellent video. I watched a different video before, but had issues making fixtures to work. I was able to use fixtures to setup and teardown database connections with your lecture. Thank you very much!

[vmramirez]

you totally nailed it with this tutorial. I had no idea just a few mins ago, now I can accomplish my task. Thank you very much!
