Developers know that testing their apps is important. Quality increases, maintenance gets easier, and time is saved in the long run. Still, most developers don’t write tests for their apps. Why? Because testing is hard, specially writing the first tests!

So, on this workshop we’re going to push through it. We’ll pick a sample application without tests and write them. We’ll cover instrumentation testing and unit testing. We’ll discuss why some components are easier to test than others and what we can do it about it.

This workshop will be taught by Sérgio Santos of Bloco. Some knowledge of Android is required.
