Root Cause

The main cause for the error is that we are pointing to insecure HTTP URL locations in the testng.xml file. For example DTD

Fix

The fix is to modify the http xml prologs, DTD links to secure HTTPS. Example, change the DTD specification in the TestNG XML file:

http://testng.org/testng-1.0.dtd

Modify this to HTTPS link:

https://testng.org/testng-1.0.dtd

Save the Test suite XML file.

Re-run the tests.

Alternatively, we can use the JVM argument hook [-Dtestng.dtd.http=true]. In the IDE

Run >> Edit configuration we can add the JVM hook.
