Talk: Structure and Interpretation of Test Cases

Throw a line of code into many codebases and it's sure to hit one or more testing frameworks. There's no shortage of frameworks for testing, each with their particular spin and set of conventions, but that glut is not always matched by a clear vision of how to structure and use tests — a framework is a vehicle, but you still need to know how to drive.

This talk takes a deep dive into testing, with a strong focus on unit testing, looking at examples and counterexamples in different languages and frameworks, from naming to nesting, exploring the benefits of data-driven testing, the trade-offs between example-based and property-based testing, how to get the most out of the common given–when–then refrain and knowing how far to follow it.
