Very nice. Could I please ask for a separate test rather than extending the current one.

Thank you for your work, if you can please update the PR with the suggested changes, I will then happily merge.

@thomas-mangin san Thank you for your kind review!

What tests does this expect to add?I would like to know if you would like 🙏

[thomas-mangin]

You are welcome.

The test you wrote is good but it is using an existing file. If you create a new configuration and test files instead, it keeps the new test separate.

The configuration file needs to be created in etc/exabgp and a .ci and .msg file created in qa/encoding. qa/bin/functional can be used to run the new test.
