How to test TypeScript type definitions with Jest
The library we're going to use to execute these static type tests is one that I made called jest-tsd. It's a wrapper around tsd to make it really easy to use with Jest.

How I unit tested types
Nice. Have you checked out tsd? Would you consider your library to be a viable alternative to tsd?

Typing is good but testing is better!?
But even with a very strict TS/ESLint configuration, you can't avoid a typing error. I looked for libraries to test types and I was very surprised to see that it is not a very common practice and there is not much choice. The most popular one seems to be tsd, unfortunately like all the other libs I found, it does not integrate with existing tools.

How to generate declaration for only public members of a package?
Yep. Similarly I'm surprised there's no built in way to test typescript definitions, so I end up using tsd.
