for example if updated, bbcfood now includes coverage for category, cuisine, ratings, ratings_count, dietary_restrictions & keywords with a current pull. These are all covered via schema so they require no update to the scraper.
Test coverage can be expanded/reduced without requiring any changes to the source code it references; so initially, yes it seems that it's valid to report changes in coverage despite no modification of the recipe scraper.
In the case of methods that always directly return the result of calling the recipe scraper's superclass method with the same arguments, I think it's debatable whether the test coverage is exercising the scraper (bbcgood in the example here), or the superclass -- or perhaps both?
