Actions may be sent through screenshot recognition, operation interface, ADB or other supported tools. Which path to use depends on the scenario.
Understand the essentials
"Look at the screen and then click" is just one way, and the interface controls the capabilities and limitations of interacting with images.
A practical example
Take a hypothetical example: a tool can click a button, but it may not be able to read the internal state of the application or confirm the save.
What to check or try
- Start by understanding what the tool can see and do.
- Use a test app.
- Record input and output.
- Independently verify results.
