Show HN: Factory-JS – TypeScript dummy object generator for testing
I made Factory-js inspired by factory-bot (https://github.com/thoughtbot/factory_bot), supports Prisma and Drizzle ORM and more. TypeScript is now widely used in both backend and frontend, but there is no de facto standard factory library. I'm developing a web application using Prisma, trpc, and nextjs, but I was struggling with how to write more beautiful and readable back-end tests. That's why I made factory-js.

Seeding the DB: Best approach?
Not sure if you want the execution speed to be faster, or the development speed. If it's development, you can use FactoryBot in a script to generate data easily once you have your factories set up.

How to optimize factory creation.
The factory-bot gem is used in almost in all of our spec files and it make our set up much more easier than when we use fixtures. Here is the tradeoff, the easier the gem is to use, the more likely you’ll end up with some pain to control its usage. And when the times come to tackle slow tests, the best bet you can take is to start digging into you factories because it’s likely they are the primary reason why your test suite is slowing down

Efate Test Generator Series: Extending the library
Efate is actually the second test fixture library I've written and there were several lessons I learned after using the first iteration for several years myself. The first version was influenced a great deal by factor_girl (called factory_bot now), with a heavy dependency on strings to define and create the fixtures. It also wasn't very modular. You couldn't just import a specific fixture, you had to bring in the whole library. And it wasn't very extensible, if you needed to define custom behavior for how a field should be created, it wasn't very pretty.

Gnarly Learnings From June 2022
As we continue to level-up our skillsets as developers in Rails, the utility of POROs (Plain Old Ruby Objects) becomes more apparent and appealing. Sometimes, the business object(s) you create do not require persistent storage to a database and are, therefore, outside of the scope of an ORM (Object Relational Mapper) like ActiveRecord. But how do we maintain simplicity in our test suite and continue to leverage helpful testing libraries like FactoryBot without one? This instructional article explores how to implement factories for POROs including common pitfalls, building nested resources, and factory linting.

Test Data Factories in Javascript
In the ruby world I'm a fan of factory_bot for generating objects that will serve as test data in my unit tests. I had a bit of time to kill this evening and thought it would be fun to implement the subset of the functionality that I use in factory_bot in javascript to see how I would approach it.
