Compared to tests in the repository root, tests in the package have many downsides: * Unless explicitly excluded in find_packages(), tests and their support code effectively become a part of public API. This, unfortunately, happened with FHDLTestCase, which was never intended for downstream use. * Even if explicitly excluded from the setuptools package, using an editable install, or setting PYTHONPATH still allows accessing the tests. * Having a sub-package that is present in the source tree but not exported (or, worse, exported only sometimes) is confusing. * The name `nmigen.test` cannot be used for anything else, such as testing utilities that *are* intended for downstream use.
