Kubernetes API Mocks

This folder contains all mocks and machinery to interact with a fake Kubernetes API.

Usage

1. Instantiate Fake

Inside a testing function, instantiate Fake by sharing the test context t and namespace name:

import "github.com/redhat-developer/service-binding-operator/test/mocks"

f := mocks.NewFake(t, "namespace")

2. Add Mocked Objects

Add mocked objects are you need.

f.AddMockedUnstructuredSecret("db-credentials")

3. Instantiate API Clients

Instantiate a fake API client, with:

fakeClient := f.FakeClient()
fakeDynamicClient := f.FakeDynClient()

Unstructured List vs. Typed Resource

As you may notice, in mocks.go we have methods returning typed Kubernetes objects, and sometimes returning unstructured.Unstructured. That happens because when using List with the dynamic client, it fails on parsing objects inside:

item[0]: can't assign or convert v1alpha1.ClusterServiceVersion into unstructured.Unstructured

However, using Unstructured it does not fail during testing.
