-# Equivalence Testing
-
-Equivalence testing is to evaluate the similarity of image or audio results. 
-Before conducting testing, please follow the instructions below to configure the virtual environment.
-
-## Configure Virtual Environment
-
-### Create Virtual Environment
-
-```
-$ python -m venv EquivalenceTest.venv
-```
-
-### Managing Packages with pip
-
-```
-$ pip install pillow
-$ pip install numpy
-$ pip install sys
-```
-
-## Run Equivalence Tests
-
-### Image Equivalence Testing
-
-```
-$ source EquivalenceTest.venv/bin/activate
-$ python compareImg.py <PATH/TO/Image1> <PATH/TO/Image2>
-$ deactivate
-```
-
-Example: 
-```
-$ python compareImg.py $benchmark_bin_dir/BuddyResize_length_500_500_BI.png $benchmark_bin_dir/OpenCVResize_length_500_500_BI.png
-```

 Please build the "AudioValidationLib" target in CMake.
 It would generate a dynamic library for CFFI to use.

 The test case should be a python file with a class inherited from AudioTest.
 You would need to modify CWrapper.cpp to add new function wrappers for the new test case.
 The class should have a method named "run" which will be invoked by the main.py.
