+## Media Testing ##
+---
+#### Writer :
+The Writer Test Suite validates the writers available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+mmm frameworks/av/media/libstagefright/tests/writer/
+```
+
+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/ExtractorFactoryTest/ExtractorFactoryTest /data/local/tmp/
+
+To test 32-bit binary push binaries from nativetest.
+
+adb push ${OUT}/data/nativetest/ExtractorFactoryTest/ExtractorFactoryTest /data/local/tmp/
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/extractors/tests/extractor.zip).
+Download, unzip and push these files into device for testing.
+
+```
+adb push extractor /data/local/tmp/
+```
+
+usage: ExtractorFactoryTest -P \<path_to_res_folder\>
+```
+adb shell /data/local/tmp/ExtractorFactoryTest -P /data/local/tmp/extractor/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest ExtractorFactoryTest -- --enable-module-dynamic-download=true
+```
