 Have in mind. This is a first draft. That covers mainly thoughts that popped into my mind.
+Transcript from my talk about testing.
+
+If you are not yet a convert to testing, you may have heard your colleagues banging the drum about the value of testing, tried it and found it slow,
+complex and distracting or even unnecessary.
+
+And yet, there is this little nagging voice that asks: Are you missing something? Should you push yourself again and master this domain?
+
+YES! Try it! We will guide you.
+
+If you have alreday some experience with testing tools like Jasmine or Jest, then you are most likely familiar with the key words:
+- Describe

+But more often that is just the conclusion we come up when we don't know how test a certain piece of code.
+We then often say: This can't be tested followed by 
+There is nothing to test here.
+
+This is wrong, and let's be honest. Every responsible and professional developer knows that automated testing
+is part of the job. That's how we have learned it. Right? 
+Closing a given task without having written a single test for it? We don't do this. Right?
+We want to professionals!
+We want to be good developers!
+We want to be heros.
