Ok I made my nice automations, but edge cases are always difficult to test.
Sure I can go to developer tools and set special states, but I need to switch many windows and find things around. I have hundreds of devices and dozens integrations, not easy to check everything.
In the automation view I now have the lovely traces view, where I can see how things are going, why not adding a simulation mode where I can easily Change triggers and states used in that single automation, and see how it behaves.
We want to go ever more pro? I can set different values for the states and save them together with the automation, so if I edit it in the future I can still quickly check that everything works. Without having to wait that day when the temperature reached X degrees, the sun is doing something strange and one entity is not available for some reason.
We can call it unit tests for automations?
