When requesting an instance for a plugin, \Drupal\Component\Plugin\Factory\DefaultFactory throws an exception telling you there is no plugin class defined, even if the entire plugin is unknown to the system. We should throw a dedicated exception when the plugin does not exist, so it's much clearer that the plugin ID contains a type or that the system can't find the plugin.

Here is a partial test. I'm still trying to wrap my head around getMock().

I'm actually not quite sure how to test this. It's not an API implementation and we'd have to test the human-readable exception message, as we use PluginException for any kind of plugin-related exception.

Hi, I have the same, but then with taxonomy_index_tid.

Got error 'PHP message: Uncaught PHP Exception Drupal\\Component\\Plugin\\Exception\\PluginException: "The plugin (taxonomy_index_tid) did not specify an instance class." at /httpdocs/web/core/lib/Drupal/Component/Plugin/Factory/DefaultFactory.php line 79'

Very open to solutions how to remove the instance class?
greetings, Martijn
