+# Running E2E Tests Locally
+
+Reference the [Akri developer guide](https://docs.akri.sh/development/test-cases-workflow#run-the-tests-locally) for details on running locally.
+
+## Displaying Output
+By default, pytest captures output. If you always want to disable output capturing when running pytest through poetry, you can set the `PYTEST_ADDOPTS` environment variable:
+
+```sh
+PYTEST_ADDOPTS="-s" poetry run pytest -v | tee output.log
+```
+
+## Running a Specific Test
+A specific test can be executed by specifying its file and name like so:
+```
+poetry run pytest  test_core.py::test_device_offline -vvv
+```
