> Adopting RxJava means fixing all the bugs in everything up front. That is why it feels complex.

I disagree with this. It mentally changes the thought processes when debugging, which was the biggest issue that was brought up.

> Does test user creation need to be bug free? I don’t know. It feels like something where productful test user creation can ship with bugs, even if in reality your test code harnesses should not be buggy.

It should be bug free at Netflix scale. My service created more customers daily than Netflix signed up monthly. It also sat in the middle of Growth. People use it to gate deployments. It needs to work flawlessly (or at least consistently).

This was part of some “testing in production” type scheme?

Are there any talks or blog posts on how y’all wired this up, lessons learned etc?

No this all happened in preprod. Every team in the growth space ran their own tests across the various permutations of users (country, payment type, plan, ... at the time free trial, feature flags) to determine if their code was valid and worked to go to production. Each team continuously deployed independently. Given that we also were continuously integrating as well... you get a lot of customers created.

Sorry no talks.
