I was dissatisfied with the available fixture/test data generation tooling for Obection.js and Knex, so I ported factory_bot from Ruby to Typescript. I’ve called it Fixture Riveter [0]. It’s more verbose than the other similar tools (factory_girl for javascript, Fishery for typescript), but it’s extremely versatile and supports factory_bot’s full api.
