SafariDriver can't clear cookies

_SafariDriver deleteAllCookies bug README.md

SOLUTION/WORKAROUND: See SafariBugWorkaround.java in this gist for a solution to the problem. Feel free to test it yourself by running TestDriverCookieDeletion.java with the substitute method.

---

I've filed the following bug at Apple Feedback Assistant: https://feedbackassistant.apple.com/feedback/6935056

SafariDriver WebDriver deleteAllCookies API does not delete cookies

SafariDriver does not delete cookies when the WebDriver driver.manage().deleteAllCookies() gets called.

Specifically, in the Selenium Java client the method call would be: driver.manage().deleteAllCookies(); // WebDriver.Options::deleteAllCookies;

For a short, self contained, correct (compilable) example, see this Github Gist: https://gist.github.com/gwpantazes/3bc7af273bd80695383c40c90c3938d7 . The example compares behavior of Chrome, Firefox, and Safari. Safari fails to delete the cookies, while the other browsers completely delete the cookie list as expected.

Steps to reproduce: (The following steps are done through scripting in order to hit SafariDriver)

• Start a SafariDriver instance
• Navigate to https://www.apple.com
• Check all current cookies (notice there are some cookies)
• Use the WebDriver to delete all cookies (driver.manage().deleteAllCookies() in Java Selenium Client)
• Check all current cookies again. Observe that cookies are still there; the cookies were not deleted.

Expected Result: The cookies would all be deleted.

Actual Result: All the cookies are still there.

Related issues elsewhere:

• This issue was closed because Apple maintains SafariDriver SeleniumHQ/selenium#1196 (and its duplicate, SeleniumHQ/selenium-google-code-issue-archive#5212 )

Environment

• MacOS Mojave 10.14.5 (18F132)
• Safari Version 12.1.1 (14607.2.6.1.1) (and corresponding SafariDriver)
