This major release has a breaking change in how snapshots are deduped when a snapshot is recreated. This usually happens because of an automated retry where a test case with a Happo snapshot fails after the Happo snapshot has been made, and then the Happo snapshot is created once more. Before this release, the retried snapshot would get a -2 suffix. With this release, the previous snapshot will be overwritten instead.

What's Changed

• Allow applyConstructedStylesPatch to take a window argument, expose as takeDOMSnapshot.applyConstructedStylesPatch() by @lencioni in #76

Full Changelog: v4.0.0...v4.1.0

This release adds some code to CSSStyleSheet.prototype that aims to capture constructed styles correctly for screenshotting. We are considering it a potentially breaking change because if your code is calling CSSStyleSheet.prototype.replace or CSSStyleSheet.prototype.replaceSync followed by a call to CSSStyleSheet.prototype.insertRule with an index or CSSStyleSheet.prototype.deleteRule, we will show an error message. We believe this scenario is uncommon and this allows us to keep our implementation simpler.

If you encounter this, please reach out to support@happo.io or open an issue.
