Ask HN: Do You Test in Production?
20 by bradwood | 26 comments on Hacker News.
There are a lot of blog posts talking about the fact that testing in prod should not be a taboo like it may have been in the 90s. I've read some of these [1] [2], I get the arguments in favour of it, and I want to try some experiments. My question is -- how does one go about doing it _safely_? In particular, I'm thinking about data. Is it common practice to inject fabricated data into a prod system to run such tests? What's the best practice or prior art on doing this well? Ultimately, I think this will end up looking like implementing SLIs and SLOs in PROD, but for some of my SLOs, I think I need to actually _fake_ the data in order to get the SLIs I need, so how to do this? Suggestions appreciated -- thanks. [1] https://ift.tt/TH4a0PG [2] https://ift.tt/h7JODsR
