 #### Running unit tests
 
-* Open Event uses Postgres database for testing. So set `DATABASE_URL` as a postgres database. Here is an example.
+* If you have docker installed and want to run tests faster, run
 
-```sh
-export DATABASE_URL=postgresql://test_user:[email protected]:5432/opev_test
-# format is postgresql://USERNAME:PASSWORD@ADDRESS/DATABASE_NAME
-export APP_CONFIG=config.TestingConfig
+```shell script
+./scripts/test_db.sh
 ```
 
-* Then go to the project directory and run the following command:
-```
-python3 -m unittest discover tests/
+And set appropriate value of `TEST_DATABASE` in `.env`
+
+```shell script
+TEST_DATABASE_URL=postgresql://test:test@localhost:5433/test
 ```
-* It will run each test one by one.
 
-* You can also use the following command to run tests using nosetests:
+* Then go to the project directory and run the following command:
 ```
-nosetests tests/
+pytest tests/
 ```
