-If you copy the snippets into our test file and run godog again. We should see the step definition is now pending:

+        s.Step(`^there should be (\d+) remaining$`, thereShouldBeRemaining)
+}
+```
 
-You may change **ErrPending** to **nil** and the scenario will pass successfully.
+Create and copy the step definitions into a new file - `vim godogs_test.go`
+``` go

 By now, you should have figured out, how to use **godog**. Another advice is to make steps orthogonal, small and simple to read for a user. Whether the user is a dumb website user or an API developer, who may understand a little more technical context - it should target that user.
