Observing Change: A Gold Master Test in Practice

by Jake Worth

Published April 25, 2017 in Programming

Tests try to observe change. But are some systems too big to observe them all? What if we need to test a function with a very complex output?

In this talk, we'll explore a Gold Master test– a special test for evaluating complicated legacy systems. We'll look at how this test takes an input, such as a production database, runs it through a transformative function, and then compares the output to an approved version of the output.

Testers of every experience level will leave this talk with a new technique for evaluating complex environments, and a broader conception of what a test can be.
