I'm not saying yours is like that, but I've definitely seen that happen.
- end to end integration tests - if they are APIs, they for the most part have a Postman collections in the repo. If they are event based lambdas, they have the standard
if __name__ == "__main__":
- build pipeline and manual resource creation. It’s so easy to export a SAM template from the console it’s criminal to not at least do that. But, yeah we have a CodePipeline to do that.
I have been on the other side though of inheriting a lambda and wondering how the hell did they go through the write->debug->fix cycle? Did they actually load it to AWS first? I spent a day creating a “test harmess”. Not real AAA unit tests, just something I could run locally to debug.
