How do you set "record" mode on?

[skywalkerdude]

I went through the documentation and it's not clear how I can mark a particular preview for Prefire to "record" a new snapshot. Could someone help elucidate?

Hi! By default, all #Previews fall under test generation. To record snapshots you need to run the scheme with tests, where PrefireTestPlugin is connected. If you want not all previews to be subject to snapshot generation, you need to create a file in the root of the project - .prefire.yml with the following content:

test_configuration:
  - preview_default_enabled: true

After that, if you want the preview to participate in recording a snapshot, you need to mark it with the .prefireEnabled function:

#Preview {
    Text("")
        .prefireEnabled()
}

It is not necessary to enable record mode itself, if no snapshots have been recorded before, it will detect and record it by itself.

Thanks for the speedy response!

My question pertained less to the initial recording, but more to updates. For instance, let's say I have a test suite already established. Then I update a view, so I need to update the snapshots. What is the easiest way to do that? Is the only way to manually find the images and delete them? Or is there a way to mark on that individual test to overwrite the existing image to reflect the updated view?

friendly ping @BarredEwe :)

The easiest thing to do is delete the file you want to overwrite)
