无法从浏览器的本地存储中删除项目

Question

I am developing automated tests using Selenium in Java. I want to delete local and session storage, cookies etc. to have "clear" WebDriver. I need it to logout from the site and use the same WebDriver for all tests instead of closing and opening browser for each test case.

When I delete the whole local storage as is shown on the picture - it is deleted. Then I reload the page. I am not logged out and all local storage items appear again.

Then I delete only active_user_session item using 'delete' key on keyboard. Then I immediately find myself logged out.

This is strange thing... Why when I delete all storage I am not logged out and information was restored when I reload the page. But when I delete only one active_user_session item I was logged out immedeately???

Ok. Let's go to the code.

((JavascriptExecutor)(driver)).executeScript( String.format(
                "window.localStorage.removeItem('%s');", "access_token"
        ));

This one works fine. But I need to delete active_user_session item it seems...

((JavascriptExecutor)(driver)).executeScript( String.format(
                "window.localStorage.removeItem('%s');", "active_user_session"
        ));

This code does not work: active_user_session is still there!!!

The more funny thing:

    ((JavascriptExecutor)(driver)).executeScript(
            "window.localStorage.clear();"
    );

Deletes all except active_user_session item!

Whyy??? Can you explain please? May be I don't know something... Thanks!

Answer 1

Try using this

 driver.getSessionStorage().clear();
 driver.getLocalStorage().clear();

Answer 2

Try this - will clear everything from your browser the good old fashioned way - but completely automated otherwise (ie cookies, logins, etc. will all be requested again)...
