+# Test 
+
+This folder holds tests for the code in the `src/features/` directory, which implements the features used for Random Forest and BiLSTM methods. It also includes tests for the  code in the `src/models/` directory, which contains the data models used for preprocessing and feature computation. The tests were written using [PyTest](https://docs.pytest.org/en/7.2.x/).
+
+
+## Execute tests 
+
+To run all the tests, execute the following command from the **parent** directory: 
+
+```
+python -m pytest test/
+```
+
+To run a specific test or subgroup of tests, specify the path. For example, to run only the tests of the features code, execute: 
+
+```
+python -m pytest test/features/
+```
+
+And to run only the tests of the entity model: 
+
+```
+python -m pytest test/models/test_entity.py
+```
