+#### Extractor :
+The Extractor Test Suite validates the extractors available in the device.
+
+Run the following steps to build the test suite:
+```
+m ExtractorUnitTest
+```
+
+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/ExtractorUnitTest/ExtractorUnitTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/ExtractorUnitTest/ExtractorUnitTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://drive.google.com/drive/folders/1Z9nCIRB6pGLvb5mPkF8BURa5Nc6cY9pY). Push these files into device for testing.
+Download extractor folder and push all the files in this folder to /data/local/tmp/ on the device.
+```
+adb push extractor /data/local/tmp/
+```
+
+usage: ExtractorUnitTest -P \<path_to_folder\>
