Is there a way to unit test code that uses AudioKit in isolation?

Question

AudioKit seems very tightly coupled with hardware that it's being run on. For example, simple let mic = AKMicrophone() run on simulator can crash if you plug in headphones to your computer.

Is there any way to configure the AudioKit in a way to isolate it from hardware? Right now it seems impossible to me to reliably unit test any code that touches AudioKit. Let alone doing it on the cloud CI.

Am I missing something?

Actually AudioKit itself is tested using TravisCI.

https://audiokit.io/tests/

Basically, we render the audio offline to a buffer and check the MD5 of the result to a known value.

Instead of using the AKMicrophone, which you can't rely on for tests, send generator output (we use a basic sine wave) into the processing nodes.

I was rather thinking of testing more basic usage. F.e. a way to create mock object of `AKBooster`, `AKMicrophone` and so on. A protocol to conform to or something :) – dontgonearthecastle Jan 02 '20 at 10:41
I don't feel like that would test the essence of these things. Its a lot different than traditional testing for iOS or web. – Aurelius Prochazka Jan 04 '20 at 18:49
But it would allow developers to unit-test code that uses AudioKit :) – dontgonearthecastle Jan 07 '20 at 07:26
