How to control the download of files with Selenium + Python bindings in Chrome

Question

Where can I find the documentation that describes the options I can use with Selenium and Chrome web browser? I want to open a link in a web browser (to get credential) but

Answer 1

The path you declared for the default directory is invalid. Either escape the back slashes or provide a literal string.

options = webdriver.ChromeOptions()
options.add_experimental_option("prefs", {
  "download.default_directory": r"C:\Users\xxx\downloads\Test",
  "download.prompt_for_download": False,
  "download.directory_upgrade": True,
  "safebrowsing.enabled": True
})
driver = webdriver.Chrome(chrome_options=options)

Here are the available preferences:

Answer 2

It makes all the difference in the world to use the forward slash "/" when specifying the directory in which you want things to be downloaded.

I'm guessing this is because that directory will be exported to something like the Powershell, where the usual backslash "\" won't properly work.
