+## Case Name: check-xrun-injection
+## Preconditions:
+##    Need to enable CONFIG_SND_PCM_XRUN_DEBUG in kenrel config
+## Description:
+##    check xrun injection during playback/capture
+##    default duration is 10s
+##    default interval time of xrun injection is 0.5s
+## Case step:
+##    1. Parse TPLG file to get pipeline
+##    2. Specify the audio parameters
+##    3. Run aplay or arecord on each pipeline with parameters
+##    4. do xrun injection during playback or capture
+## Expect result:
+##    The return value of aplay/arecord should be 0
+##
