Have you ever wanted to replace that unsupported, obsolete library, but found it impossible because it’s scattered all over your code?

We, developers, engage with third party libraries or APIs in our day to day work. It can even be a library your co-worker wrote, or some framework you’ve decided to use because it’s the best you could find at the moment.

In this talk I’ll show how I use third parties in a way that they’re easy to replace and test. I’ll also add in a little bonus and show how you can write specific tests in order to discover breaking changes before you crash in production :)
