firstname.lastname@example.org is out with the reworked persistence strategy that now works on the browser tests too! Give it a go if you've already upgraded to kotlin 1.7.0.
WTH is klip you might ask? Well it's a test snapshot library for the entirety of KMP powered by a tiny kotlin compiler plugin. In short it lets you assert current state of your test output data vs some previously frozen version of it to ensure consistency and no changes. If you're familiar with jest snapshot testing - it's exactly that but for KMP.
