Apple MacOS allow downloaded programs to run

In MacOS, when we try to run a standalone program or open an app downloaded from Internet, then MacOS's security will prevent us from running the program.

In order to execute the program or app, the following commands can be executed in Terminal to remove the quarantine attribute associated with the file.

Unblock a standalone program

sudo xattr -d com.apple.quarantine /path/to/your/program

Unblock an app

Recursively remove the attribute in the app bundle

sudo xattr -rd com.apple.quarantine /path/to/YourApp.app

Import self signed in Linux for Chrome / Chromium headless testing

Chrome / Chromium browser offers headless mode, which is quite useful to run tests via Selenium WebDriver in CI servers. However under some circumstance your test will hit a server with self signed certificate or invalid certificate or expired certificate. This may happen for developers trying to write tests against a server started on localhost with self signed certificates or testers trying to write tests against non-production servers with expired certificates (invalid certificates). Chrome / Chromium browser ignores the SSL errors when running in non-headless mode. However in CI servers, then it should be running in headless mode and currently we cannot ignore the SSL errors for tests accessing non-localhost websites. This blogs explains the steps for import a certificate into Linux's trust store, which will make the Chrome / Chromium browser to trust the self signed certificate.  Please do not apply these steps in production servers as it will make server vulnerable to ...
