-You can test `getFromDB` by either instantiating a testing database, or you can simply create a mock implementation of `DB` using mockery. Mockery can automatically generate a mock implementation that allows us to define assertions on how the mock was used, what to return, and other useful tidbits. We can add a `//go:generate` directive above our interface:
-
-```golang title="db.go"
-//go:generate mockery --name DB
-type DB interface {
-	Get(val string) string
-}
-```
+We can use simple configuration to generate a mock implementation for the interface:
 
 ```yaml title=".mockery.yaml"
-inpackage: True # (1)!
-with-expecter: True # (2)!
-testonly: True # (3)!
+with-expecter: True
+packages:
+	github.com/org/repo:
+		interfaces:
+			DB:
 ```
 
-1. Generate our mocks next to the original interface
-2. Create [expecter methods](features.md#expecter-structs)
-3. Append `_test.go` to the filename so the mock object is not packaged
