You should maybe name this MockAudioConsumer, as it behaves like a mock. The
only implementation you need is to record how many times the method gets called.

+
+FakeAudioConsumer::~FakeAudioConsumer() {}
+
+void FakeAudioConsumer::AddAudioPacket(std::unique_ptr<AudioPacket> packet) {}

You could increment a counter here, which would let you set expectations in
tests.

Ok sounds good, I will give this a try and see if I can make the test ... test
something :)

+base::WeakPtr<FakeAudioConsumer> FakeAudioConsumer::GetWeakPtr() {
+  return weak_factory_.GetWeakPtr();
