#maintainability

Hi @wim-leers,

I've added the first draft of the BlockComponentTest. To do so, I've created a xb_test_block to populate a basic block and I'm testing the plugin id and the cache tags just to see if this is the correct approach for this test. If so, I'll continue adding new tests to it.

Thanks!

I've added both @avpaderno and @darktek to the maintainers. Thanks, and let me know if there's anything else I can do to help.
