D365 UI Test Designer for Chrome
More About D365 UI Test Designer
It can capture your page actions and assist you in defining actions and assertions for your tests.
The test suite that you create can be exported (and imported again). In addition to this, the extension can create a fully functioning D365-UI-Test UI Test script, which you can use for executing directly in D365-UI-Test.
D365-UI-Test can be found here: https://github.com/XRM-OSS/D365-UI-Test
