fake client for unit testing

[kevingessner]

Kubernetes's client-go includes a powerful "fake" library (https://godoc.org/k8s.io/client-go/kubernetes/fake), which provides a mock API client that handles reads and writes without a cluster. It enables unit testing of code that uses client-go. This blog post has examples of how it's used: https://medium.com/@e_frogers/unit-testing-with-kubernetes-client-go-283b11aaa7db

Could this library provide a similar mock interface? I think a fake kubernetes.client.ApiClient that works in-process instead of over HTTP (like the go fake client) would be perfect: it would be injectable into the existing clients to allow full testing.

That would be a great feature. Im using go-client for k8s and im able to do integration tests in memory. Saves a lot of time.

is this on the radar / roadmap? it would be extremely useful!

I have to write some automation using Python (I wish it could be in Golang) and a fake client or, at the very least, some documentation on how to write tests when using this library would be helpful.

Can a maintainer at least touch on this subject?

Any exact roadmap on this one?

[darktempla]

Totally agree. Usually I just look at a repos unit tests to see how the contributors have mocked out their class etc but blank stubs when look in the test folder.

Any update on this one.

just saying that i need that too, i'm currently mocking my usages of the API and this is alot of work
