@Ladicek feel free to add any comments if you think this doesn't address it sufficiently.

I'm seeing that the config example for the Core profile is excluding the following: <excludedGroups>cdi-full,se</excludedGroups> While the text explaining the config say something different: You can configure the CDI TCK to just run tests related to the CDI Lite specification appropriate for the Jakarta EE Core Profile by excluding TestNG groups cdi-full, integration, javaee-full, se, e.g. via a maven-surefire-plugin configuration like Is this correct?

[starksm64]

Yes, and the core profile TCK includes an appropriate TestNG suite file that already has this configured, so you could just run using the suite.xml without any excluded group specified:

I think @breakponchito highlights that there's an inconsistency between the text and the XML snippet. Which is fair I think, we should update the text.

This snippet misses one line to close the element:
</dependenciesToScan>
before the line 152
</configuration>
