A feature of actuarial software is generating dependency graphs of functions. Actuaries don't write the financial models that power reporting processes in standard languages (Python, Julia, C++) and instead have proprietary systems with features like this.

What systems are you thinking if?

In my experience most actuaries I interact with maintain truly horrendous spreadsheets with labyrinthine complexity.

For end to end and frontend tests, Playwright.

What's your biggest pain point when using Playwright?

We've been trying to adopt Playwright but keep having issues with flaky tests.

Yeah flaky tests are a pain, not sure if cypress is any better but other things are so much worse. To deal with flakiness I wait for page loads or network responses or locators before executing actions that might depend on these things.

I think my biggest pain point is just the slow page loads and servers at my company. Also depending on third party services and integrating with them makes it impossible to have a reproducible environment, I can't self-host our salesforce integration in testing environment.

Just finished embedding a Python component on my site - https://www.actuarialopensource.org/book/welcome.

Uses react-py. Some effort required to implement tabs and manage lifecycle of Pyodide for separate editors.
