+Now that we have our new command, we need to build our bot with Skaffold:
+
+```text
 skaffold dev --tail=true
 ```
 
+Once the container starts up, run the new command: `!devops`

+
+Oh no! Our command is borked! Back to our editor to fix the bad code:
+
+```python
+# Delete these lines
+if self.chaos():
+  return "CHAOS"
+...
+# Delete this function
+def chaos(self):
+  """
+  This does not bring joy
+  """
+  if random() > 0.5:
+    return True
+  else:
+    return False
+```
+
+Redeploy and test with `skaffold dev --tail=true` -> `!devops`

+The other engineer also wrote some tests for us, let's copy those over as well:
+
+```text
+cp demo/code/tests/devops_test_example.py tests/plugins/test_devops.py

+

+
+Checking our test output, we expect that a a url with a `.jpg` extension is returned. However, the actual image we are returning is a `.png`. Let's fix that:
+
+```python
+# tests/plugins/test_devops.py
+assert "demo/assets/devops.png" in testbot.pop_message()
+```
