There is no typescript in your tests

I was disappointed to find there is no typescript used in your tests: https://github.com/Lemoncode/redux-testing-typescript/blob/master/01%20Setup_Reducer_Test/src/reducers/spec/httpreducer.spec.ts
Name of the repo suggests otherwise

Mmm... the test it self is "ts" and by making a new you get the strong typing.

Could you please tell me what do you miss from typescript.

On the other hand, I recommend you following this samples:

They are more uptodate.
