func New ¶

func New() (*app.App, *logtest.LogRecorder, *tracetest.SpanRecorder)

New returns an App configured for testing, together with recorders for asserting on logs and spans emitted during the test. The tracer does NOT register itself as the global OTEL provider, ensuring test isolation. The metrics registry is isolated from the process-global default.

a, logRec, spanRec := apptest.New()

ctx, span := a.Tracer().Start(context.Background(), "op")
a.Logger().InfoContext(ctx, "doing work")
span.End()

spans := spanRec.Ended()
assert.Equal(t, "op", spans[0].Name)

records := logRec.Records()
assert.Equal(t, "doing work", records[0].Message)
