Introduce variables to be used as dynamic test values

[ljouon]

Hi,

As far as I understand, Maestro currently lacks a comprehensive variable system with templating capabilities for handling dynamic content in tests.

Feature Request: Implement a dynamic variable system

What about using something similar to Jinja2 templates?
With this approach, we could define dynamic variables, use conditional expressions, perform basic operations and calculations between variables, and validate results.

Or is it intended to use JavaScript blocks for this kind of functionality?

Simple example:
In a ToDo App, I would like to add a new ToDo to a list and check in a Maestro test if the count of unfinished ToDos sums up correctly.

My real-world app is much more complex, but I think you get the point.

Thanks and best regards, Lars

I'm not sure that I understand fully the ask here.
Yes, you can use JS for interpolating strings, performing maths, etc, although in your example, you'd control the state of your app and know how many todo items were added in your test and so what to expect in the total, which you could assert with a literal.

Hi. Sorry for my late reply. My use case is somewhat more complex. 😊
ToDo items can be synced from/to a backend. This means that entries may be updated without explicit input in the app.
So, before my actual test, I want to read the value after a sync, then perform actions and after that i want to check whether everything has been correctly aggregated in the UI.

As far as i understood this might be possible with the JS scripting feature, right?

Yeah, I'd absolutely use JS for this.

Where the app UI is effectively a rendering API client, the test can call the same API and get the same data so as to validate the rendering.
