What I want to do

• suppress permission prompt for push notifications in chrome browsers.

For the purpose, we can use prefs of chromeOptions in capabilities.

Example ruby code is like this.

require 'selenium-webdriver'
driver_options = {chromeOptions: {prefs: {profile: {default_content_setting_values: {notifications: 2}}}}}
caps = Selenium::WebDriver::Remote::Capabilities.chrome(driver_options)
driver = Selenium::WebDriver.for :remote, url: "http://localhost:4444/wd/hub", desired_capabilities: caps

Using chromedriver directly or using selenium-standalone-server, we could successfully suppress the notification permission prompt.

However, with docker-selenium, we could not.

Execution Logs.

Using the above ruby code, we got driver logs (driver.manage.logs.get(:driver)) and compare the debug logs of the chrome preferences file.

with standalone servers

Server launch command

java -jar ~/local/jar/selenium-server-standalone-3.12.0.jar

Driver Logs profile.default_content_setting_values.notifications is set to 2. Expected behavior. We could suppress the notification permission prompt.

It may be the issue of chrome or chrome drivers.

Thanks,

Hi @toshiya,

Were you able get this working?

[sahil1610]

@toshiya Is there a workaround for this?

[sahil1610]

@elgalu Could this be looked into? This used to work earlier and due to this we are not able to run our tests.

[elgalu]

Hi, could you send a PR adding some tests? that way we find out when something breaks, for now the PR could contain a test that re-creates the problem and will be useful to solve it plus also prevent this from happening again.
