With Google Cloud Functions, you can run your function locally using the Function Framework libraries (available in all Cloud Function languages) [0]. These libraries are used in production Cloud Functions, so you're not emulating the runtime. The feedback loop / devX is pretty simple with just 1 command to run the function locally like a library for every language.
We have some guides on local development here [1]. Our samples have system tests that use the FF.
You also can bundle your function in a container after building it with `pack build` [2]. This provides an exact container environment with things like environment variables and system packages.
We're working on improving eventing devX, but we have some `curl` examples here [3]. Connecting multiple functions together eloquently is still something to be desired though.
