There is no spreadsheet for estimating a test project. There never will be. This is because testing is not a mechanical or linear task: it's a learning process and a design process. But of course we can do a lot to anticipate the efforts and the obstacles of testing. In this masterclass, I show how you my basic approach to estimation that involves no telling of lies or fairy tales.

I will show you:

• A reference poster I use to systematically walk through the logic of test estimation.
• How to separate the things you control from the things you don't.
• How to use test activity time blocks to make a baseline testing estimate.
