+- `test-notebooks`: Boolean option to test Jupyter Notebook examples located in the
+    `examples/` directory of the external module. A `requirements.txt` file
+    should be provided in either the external module root or `binder/` directories
+    to indicate notebook prerequisites for testing. Default value is `false`, notebook
+    tests may be enabled for a repository containing notebook examples by setting
+    the value to `true`.

+```yaml

+    test-notebooks: true
