+## Running tests
+
+The framework leverages the dbt test command to run the tests. You can run all the tests in your project with the following command:
+
+```bash
+dbt test
+```
+
+If you want to run just the unit tests, you can use the following command:
+
+```bash
+dbt test --select tag:unit-test
