There is quite a lot of functionality that goes into this plugin and working with it—we have the actual importing, the plugin and configuration entity creation, the user interface for doing so, and so on.

And in this respect, we start with testing its underlying purpose, that of the product import, for which we don't need browser interactions. This means that we can use a Kernel test.
Similar to how we wrote the previous test, we can start ...
