How to Open a Specific Chrome Profile Using Python?

Opening a Chrome Profile Using Python

This question stems from an attempt to launch a specific user profile in the Google Chrome browser via Python script. The code employed utilizes the webdriver.ChromeOptions class to define the desired profile.

Error Encountered

Upon execution, the user encountered an error indicating that the to_capabilities() method requires an additional positional argument, namely "self."

Solution

The issue lies in the implementation of the to_capabilities() method within the webdriver.ChromeOptions class. To resolve it, we need to ensure that we properly pass the instance of this class (referred to as 'self' within the method) as the first argument to to_capabilities().

Steps to Open a Chrome Profile

To establish and open a dedicated Chrome profile, follow these steps:

1. Launch the Chrome browser, access the settings menu, and navigate to the "People" section.
2. Choose "Manage other people" to initialize a pop-up window.
3. Click "ADD PERSON," provide a name and icon for the profile, check the option to create a desktop shortcut, and proceed with the creation process.
4. Locate the desktop shortcut for the newly created profile.
5. Obtain the "Profile" directory name from the shortcut properties (e.g., --profile-directory="Profile 2").
6. Retrieve the complete path to the profile directory on your system.
7. Initialize an instance of Options and employ the add_argument() method to incorporate the profile directory path with the "user-data-dir" key.
8. Use the modified Options instance to instantiate a webdriver.Chrome object and launch the browser with the desired profile.
9. Enjoy utilizing your designated Chrome profile within your automated testing framework!
