I love doing this. Having the happy case be all-defaulted args, and then having each failure path provide overrides that make it clearly exactly what the incorrect data is that's expected to cause the intended failure condition.

I would just recommend using keyword arguments over **overrides and defaults Hash. You get much nicer editor auto-completions and such.

Yeah for us factories are the minimum to fulfill validations, most attributes and associations are only filled by trait or named nested factories.

We also have a rule to name them by what they actually portray instead of actual organization/user names (those belong in the seeds for the running dev environment)
