A package for snapshot testing in PHPUnit

My colleague Sebastian recently released a new package called phpunit-snapshot-assertions. In a new post on his blog he tells all about it.

The gist of snapshot testing is asserting that a set of data hasn’t changed compared to a previous version, which is a snapshot of the data, to prevent regressions. The difference between a classic assertEquals and an assertMatchesSnapshot is that you don’t write the expectation yourself when snapshot testing. When a snapshot assertion happens for the first time, it creates a snapshot file with the actual output, and marks the test as incomplete. Every subsequent run will compare the output with the existing snapshot file to check for regressions.
