ipython VS pytest

If you’re already using ipython, this isn’t a problem because you’ll already need to download most of these dependencies anyway. But if you’re not using ipython… you’ll still need to download those dependencies.

!pip install is error-prone, it is better to use %pip install, ipython even warns about this, https://github.com/ipython/ipython/pull/12954/

The git history (here is the git blame) shows it has not been updated in 9 year. Looks like a documentation issue that you should open an issue against.

Do you know IPython? It is a modern Python console that extends the capabilities of the classic builtin Python shell by offering introspection, tab completion, syntaxing coloring, as well as history. If you don't know it, I can't recommend it enough. More information can be found in its GitHub page.

There is an IPython ticket on GitHub on the topic, but it's unclear if the problem has been solved.

For further documentation on ipython using the CLI, you can refer to the GitHub link or the documentation page.

There’s one I’ve come across recently here where you’re fighting against syntax highlighting with extra error context. https://github.com/ipython/ipython/issues/13446#issuecomment...

I see. https://github.com/ipython/ipython/issues/13529

You can automate setup for developers using this simple script:

And here’s a GitLab issue requesting support for blame-ignore:

https://gitlab.com/gitlab-org/gitlab/-/issues/31423

I don’t think there’s a corresponding GitHub request, but maybe if GitLab adds this feature GitHub will have some incentive to follow suit.

In this blog post I want to demonstrate how my lab equipment such as a lab power supply or a digital multimeter (DMM) have been integrated into some pytest-based tests. Would love to get your feedback and thoughts! 🚀

Pytest: is a third-party testing framework that supports fixtures, parameterized testing, and easy test discovery while having room to add plugins to extend its functionality.

Next, you need to install a testing framework that will be used for performing unit testing in your project. Several testing frameworks are available depending on the programming language used to create an application. For example, JUnit is commonly used for Java apps, pytest for Python apps, NUnit for .NET apps, Jest for JavaScript apps, and so on. We’ll use the Jest framework for this tutorial since we are using JavaScript.

Yea, read through the pytest docs.

I absolutely agree about fixtures-as-arguments thing. Ward does this a lot better, using default values for the fixture factory. There's a long issue on ideas to implement something like that as a pytest plugin (https://github.com/pytest-dev/pytest/issues/3834), but it seems the resulting plugin relies on something of a hack.

I recommend writing a few tests. py.test makes that quite simple:

Since ITK's inception in 1999, there has been a focus on engineering practices that result in high-quality software. High-quality scientific software is driven by regression testing. The ITK project supported the development of CTest and CDash unit testing and software quality dashboard tools for use with the CMake build system. In the Python programming language, the pytest test driver helps developers write small, readable scripts that ensure their software will continue to work as expected. However, pytest can only test Python scripts by default, and errors in untested computational notebooks are more common than well-tested Python code.
