Question

I am using Selenium with sauce labs and I am trying to run testng file from command line but it's throwing me the following error since 1 week. It was working fine before. Can some one please help me in solving this?

Answer 1

The relevant info here is:

Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Your code is unable to create a secure connection to the Sauce Labs servers. Mostly, this happens because something in your network configuration is preventing it.

Since this used to work, I'd suggest that something outside of your personal control but still within your organization has changed. Your network security tooling might be interfering with connections to Sauce Labs, your proxy details might have changed or the SSL certificate bundle used on your machine might be outdated.

I'd try the following:

1. Make sure your Java SDK is up to date
2. Make sure you've properly configured your IDE or environment. If you need an explicit proxy to connect to the internet, make sure you've configured it.
3. Contact your network security team and ask whether you should be able to contact subdomains of Sauce Labs on port 80 and 443.
