+## Testing and Mockery
+
+At a certain point, it is more convenient to use a framework to generate mocks for interfaces.
+This is where the use of Mockery comes into play (https://vektra.github.io/mockery/latest/installation/).
+Depending on the operating system (macOS via Homebrew),
+install Mockery and run it in the directory with .mockery.yaml (mockery). The mocks in the mocks directory will be automatically regenerated.
+
+```bash
+# switch to src directory
+# and just run mockery to refresh the mocks
+mockery
+```
+
+Configuration of mockery is described in the .mockery.yaml file.
