Wrapping Up

Explore how to extrapolate and validate properties from specifications using a test-first approach with property-based testing. Understand the limitations of code coverage and apply negative testing inspired by fuzzing to discover hidden bugs. Gain confidence in handling complex generators and learn when to use stateless properties effectively in your projects.

We'll cover the following...

Summary

Through properties-driven development, we’ve extrapolated properties from a vague spec and tested our happy paths in a test-first approach. While a useful metric to show whether code has ...
