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.
# Functions
ClusterServiceVersionListMock returns a list with a single CSV object inside, reusing mock.
ClusterServiceVersionListVolumeMountMock returns a list with a single CSV object inside, reusing mock.
ClusterServiceVersionMock based on PostgreSQL operator having what's expected as defaults.
ClusterServiceVersionVolumeMountMock based on PostgreSQL operator.
ConfigMapMock returns a dummy config-map object.
CRDDescriptionMock based on PostgreSQL operator, returning a mock using default third party operator setup.
CRDDescriptionVolumeMountMock based on PostgreSQL operator, returns a mock having credentials in a volume.
DatabaseConfigMapMock returns a local ConfigMapDatabase object.
