What’s a Property?
Explore the concept of property-based testing to improve unit and integration tests in Scala. Understand how to define properties, leverage automatic input generation, and use ScalaCheck for more effective testing. Learn the trade-offs between property-based and example-based testing and discover how this approach helps ensure code behaves as expected across a wide input domain.
We'll cover the following...

The more tests we run, the more time it takes for them to run and for us to make sure our code behaves as expected. Moreover, there’s no guarantee that our code is bulletproof just ...
