pytest VS Babel (Formerly 6to5)

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.

Webpack (Babel) - https://babel.dev/

I do appreciate your transparency, though I disagree with the sentiment that I’m arguing from a position of bad faith.

It’s a self-evident fact that the Babel team has not shown a moment of interest in lowering their role in the JavaScript ecosystem to anything short of kingmakers. Have a gander at their GitHub README and what do we see?[1]

- “Babel is a compiler for writing next generation JavaScript.” Indefinitely.

- Over a dozen sponsor logos. An embarrassment of riches.

- A literal audio recording of a song in praise of the project.

The Babel team has a well documented history of their priorities[2], emphasizing the need for a modular approach that has no exit strategy[3]. At best, we have a case of accidental entrenchment and long term dependence on the Babel brewing as early as 2017![4]

Compare this infinite circus to the humble but popular Normalize.css, which has the express purpose to stop existing.[5]

If the Babel team wants to raise some money, they can start by putting a plan together that would codify an exit strategy. It’s certainly more noble than their current plan of barnacling on to every NPM package…

The problem was I had used some new code, Javascript's replaceAll(), that is unsupported by older browsers. And, the setup I have to automatically fix such issues (called babel) is out of date. So, while this problem appears to be resolved there, I hadn't updated that in awhile.

babel-loader(v9.1.0): allows transpiling JavaScript files using Babel and webpack.

created 6 years ago to solve the specific problem of managing the Babel repo packages
