why espower-ts-node
power-assert is a really great project which makes writing expressive test much easier. It supports a lot of different javascript flavours and tools, which is great.
ts-node is also a really great project that handles a lot of the basics that a project like power-assert shouldn't need to worry about. it's awkward for ts-node users to need to work out how to configure how another loader will handle typescript compilation when they've already settled on ts-node.
Much better that ts-node users can simply keep using ts-node as they already have, with the awesome extra testing power that power-assert gives them.
usage

passing flags to ts-node - test files distinguished by extension

I'm compiling with great.io (the latest fab js flavour) - will this work?
Probably! It just depends on how great.io handles source maps - so long as it's consistent with how ts-node handles source maps then it Should Work Fine (tm).
