Request - Creating Unit-Tests for Pipes

[neversaid]

As this library is used by more persons and more will contribute (hopefully), it would be useful to add some unit-tests, to keep coverage and detect bugs and unexpected behaviors early :).
If nobody will take this task, i would happy take this.

But before we can start over (if this makes sense for the project) we should decide what testing-framework we want to use.
My personal favor would be Jasmine (because it is used a lot by Angular too) but i am open for jest, mocha or whatever.

Feel free for discussion!
