+## Media Testing ##
+---
+#### Sonivox Unit Test
+The Sonivox Unit Test Suite validates the Sonivox library available in external/sonivox/
+
+Run the following steps to build the test suite:
+```
+m SonivoxTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/SonivoxTest/SonivoxTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/SonivoxTest/SonivoxTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/external/sonivox/test/SonivoxTestRes-1.0.zip). Download, unzip and push these files into device for testing.
+
+```
+adb push SonivoxTestRes-1.0/. /data/local/tmp/SonivoxTestRes/
+```
+
+usage: SonivoxTest -P \<path_to_res_folder\> -C <remove_output_file>
+```
+adb shell /data/local/tmp/SonivoxTest -P /data/local/tmp/SonivoxTestRes/ -C true
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest SonivoxTest -- --enable-module-dynamic-download=true
+```
