 (Because `yesod devel` passes the `library-only` and `dev` flags, matching those flags means you don't need to recompile between tests and development, and it disables optimization to speed up your test compile times).
 
+### Tests with HIE Setup

+	- recommended to run `stack build --test --no-run-tests` *before* any test files are open and that test files compile without error
