Types ¶

type MockSpan ¶

type MockSpan struct {
	Name      string
	Status    codes.Code
	StatusMsg string
	// contains filtered or unexported fields
}

MockSpan is a mock span used in association with MockTracer for testing purpose only.

func (*MockSpan) AddEvent ¶

func (ms *MockSpan) AddEvent(ctx context.Context, name string, attrs ...kv.KeyValue)

AddEvent does nothing.

func (*MockSpan) AddEventWithTimestamp ¶

func (ms *MockSpan) AddEventWithTimestamp(ctx context.Context, timestamp time.Time, name string, attrs ...kv.KeyValue)

AddEvent does nothing.

func (*MockSpan) End ¶

func (ms *MockSpan) End(options ...apitrace.EndOption)

End does nothing.

func (*MockSpan) IsRecording ¶

func (ms *MockSpan) IsRecording() bool

IsRecording always returns false for MockSpan.

func (*MockSpan) RecordError ¶

func (ms *MockSpan) RecordError(ctx context.Context, err error, opts ...apitrace.ErrorOption)

RecordError does nothing.

func (*MockSpan) SetAttribute ¶

func (ms *MockSpan) SetAttribute(k string, v interface{})

SetAttribute does nothing.

func (*MockSpan) SetAttributes ¶

func (ms *MockSpan) SetAttributes(attributes ...kv.KeyValue)

SetAttributes does nothing.

func (*MockSpan) SetError ¶

func (ms *MockSpan) SetError(v bool)

SetError does nothing.

func (*MockSpan) SetName ¶

func (ms *MockSpan) SetName(name string)

SetName sets the span name.

func (*MockSpan) SetStatus ¶

func (ms *MockSpan) SetStatus(status codes.Code, msg string)

SetStatus does nothing.

func (*MockSpan) SpanContext ¶

func (ms *MockSpan) SpanContext() apitrace.SpanContext

SpanContext returns associated kv.SpanContext. If the receiver is nil it returns an empty kv.SpanContext

func (*MockSpan) Tracer ¶

func (ms *MockSpan) Tracer() apitrace.Tracer

Tracer returns MockTracer implementation of Tracer.

type MockTracer ¶

type MockTracer struct {
	// StartSpanID is used to initialize spanId. It is incremented by one
	// every time a new span is created.
	//
	// StartSpanID has to be aligned for 64-bit atomic operations.
	StartSpanID *uint64

	// Sampled specifies if the new span should be sampled or not.
	Sampled bool

	// OnSpanStarted is called every time a new trace span is started
	OnSpanStarted func(span *MockSpan)
}

MockTracer is a simple tracer used for testing purpose only. It only supports ChildOf option. SpanId is atomically increased every time a new span is created.

func (*MockTracer) Start ¶

func (mt *MockTracer) Start(ctx context.Context, name string, o ...apitrace.StartOption) (context.Context, apitrace.Span)

Start starts a MockSpan. It creates a new Span based on Parent SpanContext option. TracdID is used from Parent Span Context and SpanID is assigned. If Parent SpanContext option is not specified then random TraceID is used. No other options are supported.

func (*MockTracer) WithSpan ¶

func (mt *MockTracer) WithSpan(ctx context.Context, name string, body func(context.Context) error, opts ...apitrace.StartOption) error

WithSpan does nothing except executing the body.
