The FastWeb Desktop Web devices of the Perfecto Lab support visual analysis of the browser screen to identify Text. The Visual Analysis command suite supported for the Fast Web devices includes the following commands:

For more information on using visual analysis, see the article on Basic visual analysis.


  • The current implementation of Visual Analysis for Fast Web supports only text recognition functionality. Image recognition is not supported at this time.
  • Many of the parameters (of all supported commands) are relevant only to a mobile device platform and are not supported for the Fast Web platform:
    • source is ignored.
    • context is ignored
    • backlight is ignored
  • Visual Relations are not supported and, therefore, the following parameters of the supported commands (see above) are ignored:
    • relation.inline
    • relation.direction
    • x.alignment
    • x.width
    • y.alignment
    • y.width
  • The Edit.Get text command is not currently supported. It is recommended to use the Selenium/Appium getText() method to retrieve the text.
