Writing tests is one of the best ways to keep your Python code reliable and reproducible. This post builds on our previous blog about Python testing with pytest, and explores some of the more advanced features it offers. We will show how to make your tests more reproducible, easier to manage and demonstrate how writing simple tests can save you time in the long run.

It pays to extract out some helper functions and / or classes from your test cases. By doing so, your tests will look simpler, the behaviour that you are testing will be more explicit, and you'll have less code to maintain.

Automated testing is an essential part of any production-quality software project. Much of the focus in the R world is on testing the individual components of a project, but for those working with {shiny} there are great tools that can test your application as if a user was interacting with it. In this blog series, we focus on {shinytest2}.

The great strength of Shiny is that it simplifies the production of data-focused web applications, making it relatively easy to present data to users / clients in an interactive way. However, data can be big and data-processing can be complex, time-consuming and memory-hungry. In this post we demonstrate how we tackled this issue in a recent project.
