 ### Regenerating test data
 
 As a convenience it is possible to regenerate the expected output from the 
 actual output. This is useful when creating new tests and also when making a
 change that affects multiple existing tests. To run use:
 
-`npm test -- --save-output`. 
+`npm run comparison-tests -- --save-output`. 
 
 Note that all tests will automatically pass when
 using this feature. You should double check the generated files to make sure
