[alsa-devel] Alsa conformance test - a new test for ALSA drivers

[Yu-Hsuan Hsu]

Hi all,

I have created an new tool "Alsa conformance test"(
https://chromium.googlesource.com/chromiumos/platform/audiotest/+/master/alsa_conformance_test.md),
which is used for verifying ALSA drivers. Here are some main functions it
can measure:
1. Correctness of hw_params
2. Stability of rate
3. Stability of step
4. Runtime of each ALSA API
5. Underrun and Overrun

I recommend to use the script "alsa_conformance_test.py" inside. Just give
it a device and then it will test the below functions automatically.
1. To make sure whether all the parameters provided by an ALSA driver can
be used.
2. To make sure whether the measured rate is the same as the expected rate.

We have used this tool to find out many issues in ChromeOS. I hope it can
help development in Linux too. If you have any problems or want more
features, please create a bug in crbug.com and assign to me (
yuhsuan at chromium.org). Thanks!

Best,
Yu-Hsuan
