How test the Web UI for Anvil Apps

Anvil Q&A
#1

We’re using Anvil to create simple web apps to control devices using API’'s.

We use CI/CD pipelines to build and test our work and deploy to docker containers

We need to test the UI’s and how they interact with the server back and device, we would normally use Selenium to do this.

Is anyone else doing something similar and what tools are you using? Anvil people, I assume you do this internally as part of your CI/CD process, can you share anything?

#2

I use pytest/selenium to set up a test infrastructure for my UI.

It was built off of this example:

Although , it doesn’t work out of the box, you’ll have to do some tweaking. But it was a great start and saved me loads of time.

thanks, pointed the team at it, they were having issues getting unique id’s or xpaths to elements in pages with multiple instances of controls.

You may want to also take a look at Playwright: https://playwright.dev/

It seems to me to be a step forward from Selenium.

In Best Practices | Playwright they propose to use user-facing attributes like text on a button over ids and xpath.
