Screen tools

`screen`

Read the iOS simulator’s or iPhone’s current screen as an outline with refs (e1, e2 …) for tap, type_text and swipe, plus a screenshot. Read-only. Arguments

Name	Type	Default	Description
`run_id`	string		The run’s id, from `verify_start` or a device tool.
`device`	string		A device from `list_devices` (its id or name): without `run_id`, drive it directly; with neither, drive this session’s own simulator. 1 to 128 characters.
`image`	boolean	`true`	Include a 390-px-wide JPEG of the screen.

`alert`

Accept or dismiss the iOS alert on screen, optionally by a button’s name as the outline’s alert line shows it. Straight and curly quotes match: Don’t Allow presses “Don’t Allow”. Acts on the device. Arguments

Name	Type	Default	Description
`run_id`	string		The run’s id, from `verify_start` or a device tool.
`device`	string		A device from `list_devices` (its id or name): without `run_id`, drive it directly; with neither, drive this session’s own simulator. 1 to 128 characters.
`action`	string	required	Accept or dismiss. One of `accept` or `dismiss`.
`button`	string		The button to press, by its name; quotes, dashes and spacing are compared as plain text, and case matters only when two buttons differ by case alone. At most 120 characters.

`set_display`

Switch the device to light or dark appearance, or turn it to an orientation. Returns the earlier values so you can set them back. Acts on the device. Arguments

Name	Type	Default	Description
`run_id`	string		The run’s id, from `verify_start` or a device tool.
`device`	string		A device from `list_devices` (its id or name): without `run_id`, drive it directly; with neither, drive this session’s own simulator. 1 to 128 characters.
`appearance`	string		The whole phone’s appearance. One of `light` or `dark`.
`orientation`	string		The way the device is turned. One of `portrait`, `landscape_left`, `landscape_right` or `portrait_upside_down`.

`path`	string		Then open this screen by the app’s own link, such as settings/profile (dev clients need the app’s scheme). At most 200 characters.
`expect`	array of strings		Text that must be on screen once the app loads. At most 10 items. Each item: 1 to 200 characters.
`wait_s`	number	`20`	How long expect waits. 1 to 30.
