Set Chrome Options for Selenium Tests.

Posted by Fernande Dalal on Tuesday, July 23, 2024

Customize and configure ChromeDriver sessions for Selenium tests on BrowserStack Automate.

A ChromeDriver session i.e. a test running on the Chrome browser, can further be customized and configured using ChromeOptions. BrowserStack supports the full complement of ChromeOptions.

Refer to the following sample capability declaration example where ChromeOptions is being used to start Chrome in incognito mode:

If you are using BrowserStack SDK, you can set the following capabilities in the browserstack.yml file:

```yml platforms: - os: OS X osVersion: Big Sur browserName: Chrome browserVersion: latest chrome: driver: 112.0.5615.28 chromeOptions: args: - incognito - --start-maximized ```

BrowserStack SDK is a plug-n-play solution that takes care of all the integration steps for you. Using the BrowserStack SDK is the recommended integration method for your project. To know more, visit the SDK core concepts page.

BrowserStack supports all the ChromeOptions that is supported in Selenium tests. You can pass any ChromeOption during the start of your test session similar to the sample ChromeOption declaration code snippet shown above.
