What is snapshot testing, and is it viable in PHP?

In a new blogpost at Sitepoint Christopher Pitt talks about snapshot testing. He first explains how snapshot testing can help test React components. Then he demonstrates how you can use our home grown package to use snapshot testing in PHP. Finally he shows pretty cool use cases for snapshot tests.

Ah-ha moments are beautiful and rare in programming. Every so often, we’re fortunate enough to discover some trick or facet of a system that forever changes how we think of it.
For me, that’s what snapshot testing is.
You probably write a lot of PHP code, but today I want to talk about something I learned in JavaScript. We’ll learn about what snapshot testing is and then see how it can help us write better PHP applications.

If you want know more about snapshot testing, check out this blogpost by my colleague Sebastian, or watch this video where I refactor some tests to use snapshots.
