Robot Framework: How to access a class property from a Robot Framework library

问题

To implement a custom function, I am trying to access the driver property from the SeleniumLibrary which looks like below in the python package:

class SeleniumLibrary(DynamicCore):

    ROBOT_LIBRARY_SCOPE = "GLOBAL"
    ROBOT_LIBRARY_VERSION = __version__

    @property
    def driver(self) -> WebDriver:
        """Current active driver.

        :rtype: selenium.webdriver.remote.webdriver.WebDriver
        :raises SeleniumLibrary.errors.NoOpenBrowser: If browser is not open.
        """
        if not self._drivers.current:
            raise NoOpenBrowser("No browser is open.")
        return self._drivers.current

I have created the webdriver using the Open Browser command like Open Browser url=${url} browser=${browser} alias=Test options=${options} executable_path=${driverPath}.

I have tried multiple commands in the robot script to access the @property driver but it is not working:

  • Log ${SeleniumLibrary.driver}
  • ${driver}= SeleniumLibrary.driver
  • ${driver}= Evaluate SeleniumLibrary.driver

Error Message: Evaluating expression 'SeleniumLibrary.driver' failed: AttributeError: module 'SeleniumLibrary' has no attribute 'driver'

我能够使用Robot Framework找到解决方案。

${SeleniumLibrary}    Get Library Instance    SeleniumLibrary
${driver}=    Set Variable    ${SeleniumLibrary.driver}
