deleteAllCookies or cleanCookie causes UnreachableBrowserException when using InternetExplorerDriver - selenium

Question

I have set up a small test suite with geb, everything is working fine with chrome and firefox, but now i wanted to extend the browsers i execute the tests on with IE and the tests always fail because of remaining cookies from previous tests (I'm still logged in after executing the login test)
To load the IEDriver i use the webdrivermanager from bonigarcia which executes Version 2.53.1.0 of InternetExplorerDriver.
Snippet from my GebConfig:
environments {
ie {
InternetExplorerDriverManager.getInstance().setup(Architecture.x32)
driver = { new InternetExplorerDriver() }
}
My test setup looks like this:
def setup() {
resetBrowser()
Database.resetDatabase()
}
The method resetBrowser() is from Geb and does this:
void resetBrowser() {
if (_browser?.config?.autoClearCookies) {
_browser.clearCookiesQuietly()
}
_browser = null
}
And here's my cleanup (also tried it without it, didn't change anything):
def cleanup() {
CachingDriverFactory.clearCacheAndQuitDriver()
}
resetBrowser() should delete the cookies, but I read, that only cookies from the current domain will be deleted. So I thought adding something like browser.clearCookies(browser.baseUrl) or browser.clearCookies("http://localhost:8080/") before, after or instead of resetBrowser() should work. But as soon as I add this line, the IEDriver stops working with the following exception (same exception is thrown when i use driver.manage().deleteAllCookies()):
org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died.

Answer 1

My Problem was not, that the cookies are not deleted, it was that LocalStorage is not cleaned!
To clean LocalStorage Geb doesn't offer any functionality yet, but this can be achieved with the following method which can be called in the setup() routine:
def clearLocalStorage() {
//first navigate to any page within the domain to which you want to clear the LocalStorage
// baseUrl can be set in
go(browser.baseUrl)
js.exec("localStorage.clear()") // and then just clear it
}
The suggestion to use the WebStorage interface of WebDriver is as far as I anderstood not possible till InternetExplorerDriver does not implement this interface!
