Add script to test the feature to add slurs via right click

[Bhargav-Dave]

Currently the newly added feature of adding slurs via right click does not have an automated script to test. Adding it would allow us to test that feature when new features are added.

I believe the action chains of selenium can be useful in creating a script for the same: https://www.selenium.dev/selenium/docs/api/py/webdriver/selenium.webdriver.common.action_chains.html

Especially the click_and_hold() (For seleciton), context_click() (For right click) and move_by_offset(x,y) (for dragging cursor to select)

Thus, if you know the element (defined as 'ele' below) in which the text is present, the line to select some word in it would go something like the following:

# create action chain object
action = ActionChains(driver)
# selecting the item
action.click_and_hold(on_element = ele).move_by_offset(30,0).release().context_click().perform()
