How do i check a cookbook has all the required dependencies?

amurleopard

foodcritic is lint for cookbooks.

foodcritic command will check for dependencies.

$ foodcritic ../local_cookbook/
Checking 2 files
xx
FC007: Ensure recipe dependencies are reflected in cookbook metadata: ../local_cookbook/recipes/default.rb:7

Here it it checking the cookbook local_cookbook and found that it is missing dependencies in the metadata.rb file.

The foodcritic checks a number of things dependencies is just one of them. foodcritic will return an empty line if all checks are passed ok.
