fake client patch does not work if object is not found

[mishindm]

We have the error after Get returning "object not found" error

client-go/testing/fixture.go

Line 146 in fb8b734

obj, err := tracker.Get(gvr, ns, action.GetName())

However k8s will create a new object if the patch type == ApplyPatchType

A basic implementation (obviously without necessary checks) but working for us:

                        if err != nil {
                                if errors.IsNotFound(err) && action.GetSubresource() == "" {
                                        switch action.GetPatchType() {
                                        case types.ApplyPatchType:
                                                body := map[string]interface{}{}
                                                err := json.Unmarshal(action.GetPatch(), &body)
                                                if err != nil {
                                                        return true, nil, err
                                                }
                                                objcopy := &unstructured.Unstructured{
                                                        Object: body,
                                                }
                                                err = tracker.Create(gvr, objcopy, ns)
                                                if err != nil {
                                                        return true, nil, err
                                                }
                                                obj, err = tracker.Get(gvr, ns, action.GetName())
                                                return true, obj, err
                                        }
