We should provide some infrastructure that makes it easy to test command line parsers:

[ ] Given a list of command line arguments and an input and output value check that the applying the parser has the intended effect.
[ ] If an arbitrary instance exists for the configuration type we can check that the parser has the intended effect for arbitrary default values.
[ ] Using optparse-applicative function to list all options check coverage

Part of this is already implemented in test/TestTools. But it would need some cleanup before it can be exposed in the library.
