SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
In my observation, mock data has tended to be used in a rather loose, slipshod, careless manner. Unlike documentation, it is treated as the garbage of software material. (Sometimes even referred to as "garbage data"). People will try to avoid writing it by using elaborate "generators" such as jFairy or zed.
Bonus: And we're talking about more than just unit-tests here! Mock values can also be used to fill in live component demos (e.g. Storybook stories), dynamic documentation (e.g. Docusaurus pages) and snapshot tests (e.g. PhantomJS screenshots).
