Right now the test suite does not contain tests for component classes with "Standard" injection support level (see Table EE.5-1 and EE.5.24 Support for Dependency Injection). The problem is such tests are missing in Java EE CTS as well. Actually CDI TCK tests some basic injection scenarios (servlet, filter, etc.) but it does not cover everything. And the division of responsibilities for testing is work in progress (see also http://lists.jboss.org/pipermail/cdi-dev/2013-October/004345.html).
Note that in Java EE 7 component classes must support the use of interceptors as well.
