Types

type Buildable 

type Buildable interface {
	Build() runtime.Object
}

Buildable allows test fixtures to use the builder pattern. The table test runner will call Build() on any Buildable objects and use the result as the test fixture.

type DynamicMocks 

type DynamicMocks struct {
	// MockResources corresponds to dynamic.Interface.
	MockResources []MockDynamicResource

	// All other fields correspond to their dynamic.ResourceInterface equivalents.
	MockCreates           []MockDynamicCreate
	MockUpdates           []MockDynamicUpdate
	MockUpdateStatuses    []MockDynamicUpdateStatus
	MockDeletes           []MockDynamicDelete
	MockDeleteCollections []MockDynamicDeleteCollection
	MockGets              []MockDynamicGet
	MockLists             []MockDynamicList
	MockWatches           []MockDynamicWatch
	MockPatches           []MockDynamicPatch
}

The mocks to run on each function type. Each function will run through the mocks in its list until one responds with 'Handled'. If there is more than one mock in the list, then the one that responds 'Handled' will be removed and not run on subsequent calls to the function. If no mocks respond 'Handled', then the real underlying client is called.

type MockClient 

type MockClient struct {
	// contains filtered or unexported fields
}

mockClient is a client.Client that allows mock responses to be returned, instead of calling the inner client.Client.

	// called.
	Handled MockHandled = iota
	// This mock has not handled the function call, subsequent mocks or the real client should be
	// called.

	// ReconcileKey is the key of the object to reconcile in namespace/name form.

	// OtherTestData is arbitrary data needed for the test. It is not used directly by the table
	// testing framework. Instead it is used in the test method. E.g. setting up the responses for a
	// fake GCP PubSub client can go in here, as no other field makes sense for it.
	OtherTestData map[string]interface{}

	// AdditionalVerification is for any verification that needs to be done on top of the normal
	// result/error verification and WantPresent/WantAbsent.
