Old :
Session is about mutation testing, why and when you should mutate your code. 
What benefits comes by mutating your code. Simply test your own tests. 
It's very helpful tool with TDD where you are exposed to a lot of wrong 
assumptions and simple syntactic errors that can propagate other errors.


New :
You write your unit tests to guard your code, but who will guard your unit tests ? 
We put a lot of trust into our unit tests, but should we really ? We are humans, and we make mistakes.
