WebDriver Capabilities
What are Capabilities?
A good description can be found here:
Not all server implementations will support every WebDriver feature. Therefore, the client and server should use JSON objects with the properties listed below when describing which features a user requests that a session support. If a session cannot support a capability that is requested in the desired capabilities, no error is thrown; a read-only capabilities object is returned that indicates the capabilities the session actually supports.
- Capabilities are options that you can use to customize and configure a Browser session
- The capabilities you want to set are passed as a formatted string to function _WD_CreateSession
- The WebDriver UDF uses the Capabilities class to pass the capabilities string to the WebDriver Exe
- Format and content of the capabilities string differ from Browser to Browser
- Some capabilities are read-only, some are read-write
Take a look at remark about Legacy capabilities.
