Hello Cal, thank you for your answer. I'm deploying my project to AWS, so I can't replicate whole production environment easily. I do deployment to "release" environment which is about the same as production one (hosted on AWS, created with the same scripts as production one), but still there are some tests I need to run in this environment.
For example: check that email is set up correctly. I need a simple test which sends an email. It doesn't matter whether I catch the possible exception in test or in Sentry. I just want to know if it's working quickly. Checking URL endpoint is a different problem. I can't simply check URL (as I do it now in django-smoked btw), because my app could be behind load-balancer where endpoints are updated gradually. The app itself have to be able to report that it works and can be plugged into load balancer. Right now I'm trying to figure out how to send few requests to wsgi app directly. Testing deployment (whole load-balancer -> nginx -> docker stack) is a completely problem and I don't want to solve it with these tests. I understand that testing app in production is anti-pattern, but after every release I open browser and try few links. I would like to do it programmatically because when I create a bunch of nodes behind load-balancer, I'm screwed with this approach... And yes, it is probably a buzz word :) I ignored it for a while but when I heard about it from third different source, I started to digging into it...
