+## Case Name: Wrapper to run a test case given with TinyALSA
+## Preconditions:
+##    TinyALSA is installed.
+## Description:
+##    This script serves as a wrapper to execute a test case script using TinyALSA.
+##    It expects the test case script file name (without path) as the first parameter,
+##    followed by other parameters required for that test case.
+## Case step:
+##    1. check TinyALSA and SoX are installed
+##    2. SOF_ALSA_TOOL environment variable is set to TinyALSA
+##    3. The test case script is executed.
+## Expect result:
+##    The test case script is executed using TinyALSA
+##
