Hi A concern is just a bunch of methods you include into a class. You can test them either independently by bringing the concern into a plain old class, or if you need to use controller methods you can bring them into a controller. There is a anonymous controller in controller specs you can use for this purpose.
However the Rails team have deprecated controller tests (and therefore controller specs) in favour of request specs, because the way that Rails controllers operate are not well suited towards unit tests (they are always a form of integration test due to the way that the Rails stack was designed). So it depends on what you are testing.
