Summary of the feature request

I am trying to use Pester to mock kubectl command for one of my ps script. I wonder that is it doable in this case? One of the command is kubectl get pods -n .... If anyone has some experience with this then it would be great.

How should it work?

Hi. Mocking depends on how your script consumes the command and the output. Do you have any details?
There's an example for mocking native applications in general here: https://pester.dev/docs/usage/mocking#mocking-a-native-application

Hi @fflaten, in my case I want to mock the command kubectl get pods -n $namespace. I have tried the way we mock with azure command but it does not work. My mock looks like this
Mock kubectl { cmd /c exit 0 } -ParameterFilter {"$args" -match 'get pods'} or even I removed the Parameters, it still calls the actual command

Is it called from a function in a module?

[ktran1005]

@fflaten the powerscript logs into azure and use kubectl to create stuffs. Therefore, it is called in powershell script. Not sure if I answer your question correctly.

Yeah, but it should work for a script. Are you able to create a minimal repro test + script?
