There are some drawbacks: - No properly lazy golden tests. This would in principle be nice when e.g. using `pretty-simple`. - Because tests can be created dynamically, they can't be listed up front without running them. This presumably makes filtering slightly more annoying to use in practice. - Terminal output is less compact than tasty, both horizontally and vertically. There appears to be no way to change this. - We end up defining an orphan `Monoid (TestDefM '[] () ())` instance, to avoid changing much downstream code. Note though that this is not strictly necessary, and could potentially be contributed upstream. - There's a warning about threads in GHCI which we can't seem to disable. - The license forbids use in commercial projects without sponsoring. Thankfully that doesn't apply here. Anyway, it's generally very impressive. It simplifies a few things for us, and will particularly help when we come to want to specify dependencies between tests.
