Pytest Tutorial - How to Test Python Code 

Thank you again for the opportunity to collaborate! I hope you folks found this insightful :)

I was literally studying unit testing in Python, and suddenly this video pops up in my feed! Amazing, high quality, free content, as always. Thanks! ❤

Amazing tutorial on Pytest over the whole RU-vid !!

Thank you for helping to understand how fixtures work 😊

Best tutorial for the pytest - crisp and clear Thanks for posting this

exactly what I wanted to get better at, thanks again

Great tutorial This tutorial made me fall in love with pycharm really. great explanation

Thank you for this course.

Straight to the Topic !! Top-Notch Descriptions of Every part of Pytest. Love this Video . Will recommend it surely 😇😇😇🤗🤗.

Great lecture! Keep up the good work!

Thank you, Can we have one such session on A/B testing too and sanity checks using statistical tests for ML models?

awesome tutorial, reading the documentation was quite excruciating :D this format is much much better. thank you

This video is friggin amazing, thanks, I leant a ton!

Thanks! Great tutorial! This has motivated me to venture into pytest more...

Great tutorial! Also I think Harry was the "teacher" for the defense against the dark arts class in like book 6 (?) in that underground class that they made to prepare

Thank you!

Great tutorial ! @iamrithmic how do you refactor function positional arguments to named parameters automatically ? I can't seems to find the information in the pycharm forum...

Thanks for this video - very useful content with really great code / examples.

Thanks!

🎯 Key Takeaways for quick navigation: 00:43 🧪 *Pytest is a testing framework for Python, catering to both beginners and professionals.* 01:10 🕵️ *Pytest's autodiscovery of tests allows easy identification based on naming conventions, requiring no explicit registration.* 02:34 📋 *Rich assertion introspection in Pytest provides detailed reports on test failures, aiding in debugging.* 03:13 ⚙️ *Pytest supports parameterized and fixture-based testing, allowing efficient test execution with various arguments.* 03:39 🤔 *Reasons to use Pytest include simplified syntax, rich assertion introspection, a powerful fixture system, compatibility with other testing libraries, and extensibility through plugins.* 06:12 🛠️ *Installation of Pytest involves using the command `pip install pytest`, with version 7.4.2 demonstrated in this example.* 08:55 🧪 *Writing basic Pytest tests involves creating functions with assertions to validate expected outcomes.* 16:17 🚨 *Pytest can test for specific exceptions using `with pytest.raises(ExceptionType)` to ensure the expected errors occur.* 19:32 🔄 *Transitioning to class-based tests involves creating classes, and Pytest provides setup and teardown methods for pre/post-test actions.* 23:16 🔄 *Pytest class-based tests can utilize setup and teardown methods to perform actions before and after each test method within the class.* 25:22 🐍 *Pytest command in terminal requires `-s` flag to print statements in setup and teardown methods.* 26:19 🛠️ *`setup` method in Pytest can be useful for creating common objects used in multiple test methods.* 28:20 🔄 *`teardown` method in Pytest can be used for cleanup tasks, like deleting objects, especially in more complicated test scenarios.* 29:43 🚀 *Overview of class-based tests in Pytest, demonstrating how to set up and use class-based tests with Pytest.* 35:14 🛠️ *Pytest fixtures allow creating reusable objects for tests, reducing redundancy and improving maintainability.* 39:31 🌍 *`conftest.py` file can be used to store and make fixtures globally accessible across different test files.* 41:12 🏷️ *Pytest marking allows adding metadata to tests, such as labeling them as slow, skipped, or expected to fail.* 47:47 🔄 *Pytest marks, including `skip`, `xfail`, and `slow`, provide additional information about test behavior and status.* 52:23 📊 *Parameterizing tests in Pytest allows running the same test logic with different sets of input values, improving test coverage and readability.* 54:58 🧪 *Parameterized testing in Pytest allows testing with different values without messy loops. Useful for testing the same scenario with different inputs.* 55:27 🎭 *Mocking is a powerful testing technique to isolate systems by replacing external dependencies with controlled implementations called mocks.* 56:51 🧱 *Mocking example: Creating a dummy database in Pytest, mocking a function using `patch`, and verifying expected behavior.* 01:12:19 🤖 *When to use mocking: Use it when tests depend on external programs with unpredictable results, like APIs, to ensure consistent test outcomes.* 01:13:27 🤖 *Exploring AI for writing tests: Brief mention of using artificial intelligence for test automation and an invitation to try ChatGPT on OpenAI's platform.* 01:22:05 🎭 *Themed Testing: Using fixtures and parameterized tests, the code is tested with a Harry Potter theme, including students like Ron Weasley and a class named "Defense Against the Dark Arts."* 01:23:16 🐞 *Debugging: When a test fails, it's essential to review and understand the code and test conditions. In this case, an oversight in the code logic was identified and corrected.* 01:24:47 🤖 *ChatGPT 4: The tutorial briefly mentions using ChatGPT 4 for enhanced AI capabilities in generating test cases, suggesting it's available for "Plus" users.* 01:25:14 🤯 *AI Understanding: ChatGPT 4 demonstrates improved comprehension by providing a more detailed and context-aware set of test cases with a Harry Potter theme.* 01:26:38 🔄 *Consistency: When updating the test prompt, ensure all relevant details are modified to avoid inconsistencies and obtain accurate results.*

Obrigado por ajuda a fazer a internet um lugar melhor para aprender algo novo!!!

Hi , awesome pytest intro !!! do you have the code in txt as well ?

Thanks to free code camp for this wonderful video. Please I would like you to make a video on how to create animation, comics and stuffs like that. ❤❤❤

谢谢作者！

🔥 lovely

How did you make it show in terminal just (venv) -> file location name?

great stuff, is source code available please?

GREAT😍

Worth the time

great stuff, but one thing is bugging me - why he doesn't use "from" in his imports? from source import service instead of import source.service as service ? Is there something I don't know about imports?

always bizarre to see you post these sorts of videos right as their topics are most relevant to me 😂 guess you’re pretty tuned into the zeitgeist lol

"We were expecting a raise but instead we got a test fail" - I feel ya

What is the plugin that autocompletes the function keys?

i don't why but i think that my vs code is crazy or when you imported source.my_functions as my_functions it telling me that there is no such module called my_functions pretty crazy right!!!!

wow 😊

Why are not we using MonkeyPatching built inside Pytest and instead using unittest ?

I would like to learn coding. I would need to start with step 1. Can anyone point me in the right direction. What to learn first?

00:55:26

Who is the guy speaking at the first 30 seconds?

Nice

❤❤❤

👍

so we need to install python, pytest, and pycharm?

But what is the point of testing a function with results that we know in advance?

Neden Türkçe altyazılı yok lütfen

Can you create a Dynamic Programming course with Python. Thanks beforehand

Good tutorial except the Mocking section which was extremely shallow. How the mock test is ever going to fail if you are the one defining the return value of the function/method and then are comparing it with the same exact value? Obviously is always going to pass.

where's the code repo ?

Guys, I think we all have a similar resume xD

pytest makes me want to write my own test framework.

to me it shows some parts of this you have memorized without properly understanding it, and this is so clear once you try to explain it. either that or you are lacking proper communication skills. Either way it amazes me to see how many people want to make videos about things they dont even understand themselves while people that do dont make videos at all.

A much better (and shorter and more realistic) intro to Pytest: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YbpKMIUjvK8.html

There is nothing that pytest does that Python's native unittest itself doesn't also do (except support plugins that painfully keep breaking).

I just suggest you, please leave teaching to someone and always teach yourself only as now in this video, you are teaching yourself. Useless teaching, it is just for who muggs the code. Waste of time😡

❤‍🔥

Thanks!
