Functions

func AddRemotes

func AddRemotes(values []resource.Name, remotes ...string) []resource.Name

AddRemotes takes a slice of resource.Name objects and for each remote, adds the remote to every object, then returns the entire list.

func AddSuffixes

func AddSuffixes(values []resource.Name, suffixes ...string) []resource.Name

AddSuffixes takes a slice of resource.Name objects and for each suffix, adds the suffix to every object, then returns the entire list.

func BuildTempModule

func BuildTempModule(tb testing.TB, dir string) (string, error)

BuildTempModule will run "go build ." in the provided RDK directory and return the path to the built temporary file and any build related errors.

func ConcatResourceNames

func ConcatResourceNames(values ...[]resource.Name) []resource.Name

ConcatResourceNames takes a slice of slices of resource.Name objects and returns a concatenated slice of resource.Name for the purposes of comparison in automated tests.

func ExtractNames

func ExtractNames(values ...resource.Name) []string

ExtractNames takes a slice of resource.Name objects and returns a slice of name strings for the purposes of comparison in automated tests.

func MakeRobotForModuleLogging

func MakeRobotForModuleLogging(t *testing.T, parentAddr string) rpc.Server

MakeRobotForModuleLogging creates and starts an RPC server that can respond to `LogRequest`s from modules and listens at parentAddr.

func NewInfoObservedTestLogger

func NewInfoObservedTestLogger(tb testing.TB) (logging.Logger, *observer.ObservedLogs)

NewInfoObservedTestLogger is a copy of NewObservedTestLogger with info level debugging instead of debug level.

func NewResourceNameSet

func NewResourceNameSet(resourceNames ...resource.Name) map[resource.Name]struct{}

NewResourceNameSet returns a flattened set of name strings from a collection of resource.Name objects for the purposes of comparison in automated tests.

func NewUnimplementedResource

func NewUnimplementedResource(name resource.Name) resource.Resource

NewUnimplementedResource returns a resource that has all methods unimplemented.

func Retry

func Retry(condition condition, numRetries int)

Retry sleeps until a condition is met or a max of numRetries times.

func SubtractNames

func SubtractNames(from []resource.Name, values ...resource.Name) []resource.Name

SubtractNames removes values from the first slice of resource names.

func SubtractNamesFromLevels

func SubtractNamesFromLevels(from [][]resource.Name, values ...resource.Name) [][]resource.Name

SubtractNamesFromLevels removes values from each slice of resource names.

func ToProtoMapIgnoreOmitEmpty

func ToProtoMapIgnoreOmitEmpty(data interface{}) map[string]interface{}

ToProtoMapIgnoreOmitEmpty is a helper to convert an interface to a map to compare against a structpb.

func VerifyTopologicallySortedLevels

func VerifyTopologicallySortedLevels(t *testing.T, g *resource.Graph, levels [][]resource.Name, exclusions ...resource.Name)

VerifyTopologicallySortedLevels verifies each topological layer of a sort against the given levels from most dependencies to least dependencies.

Types

type FakeConvertedAttributes

type FakeConvertedAttributes struct {
	Thing string
}

FakeConvertedAttributes is a helper for testing if validation works.

func (*FakeConvertedAttributes) Validate

func (convAttr *FakeConvertedAttributes) Validate(path string) ([]string, error)

Validate validates that the single fake attribute Thing exists properly in the struct, meant to implement the validator interface in component.go.

type MockBuffer

type MockBuffer struct {
	Writes []*v1.SensorData
	// contains filtered or unexported fields
}

MockBuffer is a buffered writer that just appends data to an array to read without needing a real file system for testing.

func (*MockBuffer) Flush

func (m *MockBuffer) Flush() error

Flush does nothing in this implementation as all data will be stored in memory.

func (*MockBuffer) Length

func (m *MockBuffer) Length() int

Length gets the length of the buffer without race conditions.

func (*MockBuffer) Path

func (m *MockBuffer) Path() string

Path returns a hardcoded fake path.

func (*MockBuffer) Write

func (m *MockBuffer) Write(item *v1.SensorData) error

Write adds a collected sensor reading to the array.

type ServerTransportStream

type ServerTransportStream struct {
	grpc.ServerTransportStream
	// contains filtered or unexported fields
}

ServerTransportStream implements grpc.ServerTransportStream and can be used to test setting metadata in the gRPC response header.

func NewServerTransportStream

func NewServerTransportStream() *ServerTransportStream

NewServerTransportStream creates a new ServerTransportStream.

func (*ServerTransportStream) SetHeader

func (s *ServerTransportStream) SetHeader(md metadata.MD) error

SetHeader implements grpc.ServerTransportStream.

func (*ServerTransportStream) Value

func (s *ServerTransportStream) Value(key string) []string

Value returns the value in the metadata map corresponding to a given key.

type TrackingDialer

type TrackingDialer struct {
	rpc.Dialer
	NewConnections int
}

TrackingDialer tracks dial attempts.

func (*TrackingDialer) DialDirect

func (td *TrackingDialer) DialDirect(
	ctx context.Context,
	target string,
	keyExtra string,
	onClose func() error,
	opts ...grpc.DialOption,
) (rpc.ClientConn, bool, error)

DialDirect tracks calls of DialDirect.

func (*TrackingDialer) DialFunc

func (td *TrackingDialer) DialFunc(
	proto string,
	target string,
	keyExtra string,
	f func() (rpc.ClientConn, func() error, error),
) (rpc.ClientConn, bool, error)

DialFunc tracks calls of DialFunc.
