 One recommended framework for testing in Python for the Temporal SDK is [pytest](https://docs.pytest.org/), which can help with fixtures to stand up and tear down test environments, provide useful test discovery, and make it easy to write parameterized tests.
 
+If you do use `pytest`, consider using `-s` (`--show-capture=no`) so you can see the logs live.

 An Activity can be tested with a mock Activity environment, which provides a way to mock the Activity context, listen to Heartbeats, and cancel the Activity.

-### How to mock Activities {/* #mock-activities */}
+The simplest test case we can write is to have the test environment execute the Workflow and then evaluate the results. `WorkflowEnvironment.start_local` configures a local environment for running and testing Workflows:
+
+```python
+import uuid
+
+import pytest
+from temporalio import activity
+from temporalio.testing import WorkflowEnvironment
+from temporalio.worker import Worker
+
+from activities import greet
+from workflows import SayHelloWorkflow

+    """Execute the workflow end-to-end with its real activity."""
+    task_queue_name = str(uuid.uuid4())
+    async with await WorkflowEnvironment.start_local(ui=True, ui_port=8233) as env:
+        async with Worker(
+            env.client,
+            task_queue=task_queue_name,
+            workflows=[SayHelloWorkflow],
+            activities=[greet],
+        ):
+            result = await env.client.execute_workflow(
+                SayHelloWorkflow.run,
+                "Temporal",
+                id=str(uuid.uuid4()),

-When integration testing Workflows with a Worker, you can mock Activities by providing mock Activity implementations to the Worker.
+You can also pass `ui=True` to `start_local` to see the UI.

+### How to mock Activities {/* #mock-activities */}
 
-Provide mock Activity implementations to the Worker.
+When running unit tests on Workflows, many times you want to test the Workflow logic in isolation. When integration testing Workflows with a Worker, you can mock Activities by providing mock Activity implementations to the Worker.
