Testing you can't control

This is a short, demo-led session where the audience becomes part of the test. 

Using your phones, we’ll turn the room into a live system and watch what happens as it runs in real time. 

At first, it looks like everything is working together, but small differences start to appear. 

Things don’t line up perfectly, and behaviour across devices isn’t always the same. 

It’s a simple way to see how real systems behave outside of perfect conditions, and what that means when it comes to testing them. 

Supported by a small number of slides, but centred around a live demo.
