I am looking for a locally executable test double (mock/stub/fake etc.) that can be used for replacing the Google Cloud Secrets Manager used by my application. Something like Localstack in case of AWS. This would allow me to start my app locally and on CI without using any cloud resources.
I have tried searching for it but only found old threads saying that there is none. I am afraid it might be accurate still, but wanted to give it a try here as well, maybe someone knows of a small stub that did not make the headlines yet.
