@pierredup The CI run is fixed now.

But i disabled the auto-commit.
It will reintroduce Errors.
Actual it would make the following change.
That was fixed here https://github.com/Payum/Payum/pull/989/files#diff-4f756e454705bdf3e67c480b0ca47376ac62ed3964fa4e57c9444aa81ef073e1R119

          if (method_exists($this, 'expectExceptionMessageRegExp')) {
-            $this->expectExceptionMessageRegExp('/Given \"config_path\" is invalid. \w+/');
+            $this->expectExceptionMessageMatches('/Given \"config_path\" is invalid. \w+/');
         } else {
             $this->expectExceptionMessageMatches('/Given \"config_path\" is invalid. \w+/');
         }

@Chris53897 Thanks for the changes. I made a few changes to the PR:

• Use the new DSL for Rector config
• Skip the RenameMethodRector rector for the PaypalRestGatewayFactoryTest test class as to not re-introduce the changed line
• Re-enable the auto-commit
